Campagnolo 13-speed EKAR groupset

The Strada launched as the world's first road bike for 1x drivetrains. A great bike with 1x11, but we always knew upcoming 1x12 and 1x13 groups would make it even better. Campagnolo 13-speed EKAR does exactly that.

Posted by Gerard Vroomen - 24 September 2020

The launch of Campagnolo 13-speed EKAR brings to an end a 5-year saga for me. In this post I’ll tell you all about my discussions with Campagnolo in that period, how it influenced some 3T bikes that are already on the market and what this means going forward.

Early discussions (Campagnolo 13-speed is still far away)

At Eurobike 2015, Campagnolo’s engineers and sales manager invited me to a sneak preview of their first disc brake groupset. I love these sorts of meetings, because I have always been obsessed with drivetrains, gear ratios and the like, but without any desire to get into that business. So whether it’s SRAM, Shimano or Campagnolo, if people want to brainstorm, I’m in.

The brakes they showed me were very nice, but the rest of the drivetrain was pretty standard. So with the eternal “drivetrain ratio” spreadsheet in the back of my head, I tried to convince them to go radical, to change to a 1x drivetrain and really leapfrog the existing group sets on the market.

We had a great discussion about flatmount and postmount (that was still a thing back then), on how much range future road and gravel bikes would need, how to potentially do that with 1x while getting enough range and small steps, and funnily enough I told them about wanting a 9T starting cog (remember I never had any desire to be in the drivetrain business).

I didn’t actually think any of this would happen, it was just a couple of engineers dreaming out loud. A few years later we introduced some 3T cassettes, 11-speed and starting with a 9T cog. Not because I wanted to, but because we needed it for the Strada.

When I told one of the Campagnolo engineers that we actually found surprisingly good drag numbers on the 9T cog, he said he was not surprised. Seems they had already been thinking the same things (and probably 1000’s of other things I had never considered).

Strada

Meanwhile in 2017, we introduced the Strada, the aero road bike designed around comfort with wider tires and a 1x drivetrain. At the time, 1×11 was the standard, and although that works for a group of riders (and a little better with our 9-32T cassette), we also knew that 1×12 and 1×13 would make things even better. We knew several drivetrain makers were working on those, so we launched in anticipation of them appearing.

SRAM AXS

And then it went quiet. It was only in the first half of 2019 that SRAM AXS 1×12 arrived. Obviously it came a little later than we had thought, but it immediately lifted the appeal of the Strada.

12-speed electronic shifting, beautiful levers, good brakes, lightweight, it all matched perfectly with the Strada. Until today, our entire Strada line-up consists of SRAM AXS bikes.

SeaOtter 2019

I had already heard some things about a new Campagnolo 13-speed drivetrain and at SeaOtter 2019, they showed me a groupset that was everything I wanted: 13-speed, 3 cassette combinations almost exactly as I had on my spreadsheet and unbelievably: a 9T starting cog for 2 of the 3 cassette options.

The trick of starting with the 9T helps to space your cogs more closely in the middle of the cassette. It’s something crucial for 11-speed cassettes where each cog is at such a premium. But even with the abundance of 13 cogs, it does wonders.

The final EKAR groupset

As you can see in the photos, the final Campagnolo 13-speed EKAR groupset is beautiful. Carbon crank, intricate rear derailleur, “industrial chique” brake calipers and nicely sculpted (and very comfy) levers. but most importantly, 3 great cassette options:

9-36T: 9-10-11-12-13-14-16-18-20-23-27-31-36

9-42T: 9-10-11-12-13-14-16-18-21-25-30-36-42

10-44T: 10-11-12-13-14-15-17-19-22-26-32-38-44

Keep in mind that because of the 9T cog, your chainring can be a lot smaller, so a 40T chainring is probably enough on your road bike (and otherwise a 42T). That in turn shows you how generous the climbing gearing is, even on the 9-36T cassette.

One thing people may be surprised to see is that the groupset is mechanical, not electronic. I’m agnostic on the subject, I really don’t care if my shifters are mechanical or electronic.

I see an advantage for electronic on the front derailleur (automatic trim) but for 1x that obviously doesn’t apply since there is no front derailleur. Almost everything else on a drivetrain is more important to me than mechanical vs electronic.

And personally I think a little bit of reliable old-school thrown into this revolutionary drivetrain is rather neat.

Strada Campagnolo 13-speed EKAR edition

To celebrate the launch of EKAR, we’re introducing a limited edition Strada with a custom Campagnolo paint, EKAR drivetrain and Campagnolo Shamal Carbon wheels (If you’re more interested in an Exploro gravel bike with EKAR, then check this out).

A very limited number of them is available today, some more will be available in October and November. So be sure to order yours today.

Below are some more photos of the bike, while specs can be found here.

    Hi Gerard
    Today I discovered your new range of Strada 2.0 bikes and I noticed that the transmissions are exclusively Sram
    Campagnolo is forgotten with its Ekar model its 9T and 13 speed while it seemed the most successful system for the Strada model
    Is there a particular reason for this abandonment?

      At the start, availability is limited, but there’s a good chance more options will be added. However, the frame is only compatible with electronic drivetrains, so the current Ekar will not work unfortunately.

      That depends a little bit. Until 2 months ago, it would have been 1x34mm and 1x39mm for the frame, and 2x44mm for the fork. Now it is 2x39mm for the frame, 2x44mm for the fork. It’s easy to see, if the “posts” on the frame are both the same length, then it’s 2x39mm. If the front post is 5mm shorter than the rear (25mm vs 30mm), then you need the 1×34 and 1x39mm.

    I had been pining after this frame design since it’s original release. The bike arrived with crimped brake hoses (professional shop discovered when bleeding), and customer service suggested it could’ve happened at the shop upon removal. In hindsight the action and recoil of the brakes never felt quite right so I’m sure this happened during assembly with the internally routed bars. The hoses were replaced at my cost. The cassette came loose after EVERY ride, causing the drive train to wear quickly (it has since been replaced). The wheels came out of true after 100km and rear bearing shot after 1,000km. I’m 66kg and I rode this group on mostly paved surfaces and maintained it well. 3T customer service did NOTHING to resolve any issues and I’m still trying to work with Campag per 3T customer service. I could’ve have been a 3T guy for life and I still love the frame, but the experience has left a horrid taste in my mouth and I regret my purchase.

    Hi Gerard, question for you about compatibility. I purchase the Torno, the 46T Wolf Tooth chainring, and the Ekar rear derailleur and chain. The chainring I received is not compatible with the Ekar chain. 3T website makes it seem like the 46T is compatible with 13 sp Ekar. Would appreciate any advice you have. Hoping I don’t have to have custom chainring made. Need bigger ring than Ekar crankset offers and Torno is stunning. Can send pics of incompatibility if it would help.
    Thanks in advance.

      Hi Reese, that is correct, although the other sizes of Wolftooth chainrings do work with Ekar (not by design, it’s just a fluke), the tooth profile on the 46T rings is a little different and does not work. That said, there is also not often a reason to run a 46T in combination with Ekar as it gets you a pretty big gear (46×9 for example would be the same as 56×11, so that’s world champion time trial territory). If you run it with the 10-44 cassette the top gear is a bit more modest of course.

        Hi Gerard, I ordered a 36T Torno chainring that was supposed to work with Ekar from the 3T website. It is too tight on the wide teeth . Similar to other Torno chainrings I purchased previously. I will continue using the ring that I filed the wide teeth down on for now.

          Hard to say. for sure chainrings for 12-sp don’t work for 13-sp automatically, there are plenty that don’t (our 46T ring is an example, while the rest works). You’d have to check with them to see about each individual ring but then again, officially our Wolftooth rings are not 13-speed officially either but they work (except the 46T as mentioned).

    I’m getting this bike soon and I can’t wait! It’s coming to me with the Pirelli 25c width tires (I forgot which model exactly). I want to keep the tires Italian and tubeless, but want the width to be 30-31c. With the Shamal rims being 21c internal, should I go with Pirelli ZERO Race TLR @ 700x28c to achieve that? I’m thinking the 700x30c might be too wide for the frame if going tubeless. Unless you have another tire recommendation. Thanks!

    Reply
    1. Gerard Vroomen says:

      28 October 2021

      You’ll find the 25c tire is already considerably wider on the 21c rim (that’s why we spec it). The Zero race TLR is fairly new so I don’t have our in-house measurements for it, but according to Pirelli it would be 29mm wide (WAM) and 343mm radius (RAM) on a 21c rim. That’s for the standard version, not sure the TLR changes that much. I think that’s a safe bet, the 30mm version is apparently 31mm WAM and 344 RAM so the RAM is pushing it a bit (especially since there can be some variation in production).

      hi Eric,

      Normally our limited editions are fixed on an exact number. We make the frames, and that’s it. With the Limited Edition Ekar Strada frame it’s a little different. It is limited to just the Ekar groupset, so not available with other drivetrains. And the exact number depends right now on how many groups we’re getting for this bike.

    Wheelset for my Strada EKAR build.

    I intended to use a DT Swiss ERC1400 db wheelset i already own and already bought an EKAR 13 adapter/freewheel for the 240s hub in this wheelset.

    Now i am contemplating about a strictly italian build. As i would like to exploit the aero potential of the Strada, i was looking at Campa Bora WTO 60’s or 45’s. Is there a chance to get the EKAR cassette to fit on the Boras? What does it take?

    Any opinions on the Bora WTO 60 for allround riding for a >80kg guy?

    I also consider a set of Swiss Side Hadron2 625’s.

    And last … maybe a numb question … does the Strada profit from an aero wheelset the same way, as a conventional bike frame?

    Best regards
    Tom

      Hi Tom, if you get the Bora with N3W freehub, then the Ekar cassette fits. Same with the Discus 45|32, it’s also available with N3W. Unfortunately I don’t have any experience (yet) with the new Bora or with Swiss Side, only with the Discus, which was designed specifically for the Strada. But the other wheels will work too (assuming Swiss Side has an N3W freehub available). And yes, the Strada also benefits from an aero wheelset.

        Thanks again, Gerard.

        Any thoughts/opinions on the wheel depth? Up to 50 or even more? I like the DT ERC1400 a lot on my Open UP as a road setup … they feel quite efficient with 25mm/28mm Conti GP5000 mounted.

        My experiences with 3T wheels are mixed … the Discus wheel that came stock with my Exploro had 3x broken spokes and it took a long time to get those fixed via the dealer, until they finally replaced it with a fulcrum set.
        My other wheelset is a 3T DiscusPlus i28 LTD, that works perfect on a WI.DE.

          I assume a Discus C-series (C35, C60)? I don’t think you’ll have those problems with the 45|32, completely different wheelset and same hub/spokes as the i28 (different spoke length of course 🙂

          The Discus doesn’t need to be deeper than 45mm given its design and optimization for wider tires. Most other rims are narrower and so they need more depth to be as efficient with a wider tire.

            The C45/32 is 32mm wide … so when applying that 105% rule for a rim-tyre combination, that would result in a 30mm tyre, would’t it?
            3T has tested it with a Pirelli P Zero, measuring 31.6mm on the rim, didn’t they? Does that still fit in the Strada?

    Hello Gerard,

    due to crazy times in parts supply i have to shop for an EKAR groupset in several online stores. Just thought i had all parts needes for a Strada EKAR build, when i saw, that i could need flat mount adapters for the flat mount frame and the flat mount fork. Is that fact? And when i checked deeper, i saw that i will also need the appropriate srews for the brake mount … and their dimension would depend on the diameter of the Strada chainstays.
    As Campagnolo supplies several dimensions of screws for EKAR, what do i need for the Strada, please? M5x19 or 24, 29, 34, 39, 44 ?
    And do i need them for the front, too?

    This was easier with my UP and the WI.DE

      You need the bolts for a 25-29mm chainstay, so the AC18-DBSC34. For the fork, you need the fork adaptor which includes already all the bolts. That’s AC18-DBCNF4

    Hi Gerard/3T.
    Would there be plans to allow for the Strada to fit larger tyres while still retaining the aerodynamic properties the current Strada has? It seems like there are further benefits to aero and comfort to have a slightly larger tyre than the current limit at 28mm?

      Ekar is the future of the Strada! This is what we have been waiting for for a few years, so the future of Strada is finally here today. As for future models, we’re always thinking about new things, but really impossible to say if these ideas in the end work well and turn into a new model or not. Most ideas turn out to be bad in the end. 🙂

        Aesthetically, it would be great if the cable routing is fully internal, like in some recent road or even gravel bikes. And slightly more clearance to confidently accommodate 32mm tires with 21-25mm internal rims. Road bike with marginal gravel adaptations. Seems very special:)

        Gerard, this might not be best question for this forum – but how about you view on sizing of STRADA, if I may? I am 184 cm with seat set to 80 cm (from BB). Where this sits in your view? Some shops see this as absolutely in size XL as size L might end being too low and aggressive. However, your sizing chart would recommend size L. I am unsure on this..

          It’s borderline, that’s why you get varying input. In general I would take fitting advise “in person” over the general guideline based on just your height. If you’re not entirely sure, then you can also send a note to 3T customer service with info about what model of road or gravel bike you currently ride, what size, model year (or generation), stem length and how many mm of spacers under the stem. With that they can see how you can best mimic your position.

      Not really, on a 1×11 the shifter, the derailleur, the chain and the cassette isn’t compatible with 12-speed. So you would need to replace a lot of parts. Better to go directly with 12-speed or 13-speed.

    Hi Gerard, I purchased the my Strada 1×13 in January 2021, I have just spent the weekend in the Australian High Country (Victoria), climbing Mt Buller and a number of surrounding climbs, including one at 18.2%. I am so impressed with the 1×13. It never missed a beat and I was never left wanting for gearing. Awesome bike for decending off the peaks, the braking was exceptional and I am now a complete convert to the 3T and 1x. Thanks for an awesome bike.

    Hi Gerard,

    Late to the party and building an 11 speed Strada this winter for some flattish blasting around SE England. My previous plans for a ‘one bike’ were overriden by the desire to try the Strada! I’m using the Bailout which is the best compromise solution with the 11S I had already started sourcing. For me and many Strada owners the Bailout would be better with 14T replacing the 9T (to make it a 10-32). No one seems to have a 10 up solution without going to the SRAM 12S (and replacing too many parts). Any plans for an updated Bailout or are you aware if any of the other players are investing in 11S?

    1. Gerard Vroomen says:

      Hi Stephen, you mean the whole drivetrain stays SRAM and the cassette changes to EKAR? That wouldn’t work, the spacing is different and EKAR has 13-speed and SRAM 12. If you mean exchanging the whole drivetrain from SRAM to EKAR, that’s no problem on the frame side, but you would need to convert the wheel to the Campagnolo N3W free hub. Depending on the wheel, that could be easy or impossible.

    Any idea on compatibility of chain and derailleur with Rotor cassettes? I like that Rotor 13 speed cassettes fit Shimano freehubs.

      Hi Niko, actually the 13-speed ROTOR cassettes don’t fit Shimano freehubs. Only their 12-speed version fits Shimano freehubs. And even then, the spacing for ROTOR 13-speed is much wider than for EKAR (Rotor is really 12-speed spacing of say SRAM plus one extra cog, Campagnolo more or less squeezes the 13th cog into the existing space).

    Hi, struggling with 52/36 – 11/28 the new 1x 13 looks very promissing! How do you think about the Shamal wheelset with 28mm tires? Will there be versions available with Ekar and 3T wheelsets?

      Hi Jappie, as of this month, the Discus 45|40 is available in an EKAR-compatible version (although I am sure sold out again quickly, but more coming). The Discus 45|32 will also be compatible soon. That is to say, it is already compatible and if you own one already, you can switch it to the N3W freehub you need. But it still takes a few weeks before have them in stock.

    Hi Gerard,
    Looking at their new N3W freehub:

    https://www.campagnolo.com/US/en/next_3_ways

    It looks like Campy is going to launch new cassettes with 9T or even better, 13 speeds for road also.
    What do you think is more likely or makes more sense?
    A new SuperRecord 12 speed with 9t or SR 13 speed?

      Hi Daniel, I am not sure I understand your question. EKAR uses the N3W free hub and is perfect for road too. There’s no difference between the 1×13 needs for road or gravel, other than maybe the range of the cassette. But with the 3 cassettes they offer, the 9-36 is perfect for road (similar to say a 52-36 crank with an 11-30 cassette). So no need to wait for SuperRecord, the Strada with EKAR in this post is already there.

        Ekar is perfect right now, I agree, but a road specific 1×13 groupset would be lighter.
        The sram axs 1×12 is already almost 200 grs lighter than the Ekar (with less range, for sure).
        Obviously the gravel groupsets are designed to be more sturdy/strong, but a good amount of weight can still be saved IMO.
        I just was guessing (hoping:) that with the new N3W freehub launch a new 1×13 for road may be imminent.

          EKAR is around the same weight as SRAM Red AXS and lighter than Force AXS.

          And of course AXS is also for road and gravel. So if a company the size of SRAM doesn’t split it up between road and gravel, I doubt Campagnolo would.

          I also think you overestimate the weights that could be saved when making it “road-only”. The tests that these parts need to pass would be the exact same ISO tests and also technically you need the same features (it’s not like you could remove the clutch for road or anything like that). Maybe here and there you can shave off some protection, but if that saves 20g it’d be a lot. And I’d rather have the extra protection on road too.

          Of course if EKAR is not light enough for you, you can always change the crank for a 3T Torno.

    For existing users who are forced to stop using the beautiful 3T Bailout after shifting to AXS, is there any plan to make a 12s successor for it for existing AXS owners? Ekar cassettes really makes me missed the Bailout and Overdrive.

    1. Gerard Vroomen says:

      We made our cassettes because nobody was making the gear ratios we wanted. Now somebody does, SRAM’s 10-36T is pretty much the same range as our 9-32T. And of course there is EKAR’s 9-36T. So no, we don’t plan to make any more cassettes as long as the companies that actually specialize in cassettes keep making the ratios we like.

    A 10 tooth jump between cassettes on the biggest cogs with 11 speed doesn’t cause an issue for me using Apex1 so I’d have thought and 8 tooth jump on EKAR would be ok. Plus I don’t feel the need for as big a top gear when swapping to the gravel wheelset so down to a 10t top gear is fine by me! Would be good to hear it’s approved by the factory though.
    Thanks for the reply.

      Well, you can shrink your chainring to make sure your top gear isn’t too big. As for the bigger final jump, Campagnolo does a ton of testing on the shift performance and this is what they feel is appropriate. Different chain, different tooth profile, etc.

    Very interesting. Does this solve the 2 wheelsets in one bike issue that AXS doesn’t? ie- one for the road and one for gravel. If you can swap between the 9-36 for the road wheelset and 10-44 for the gravel wheelset on the same bike with the same chain and chainring (40t sounds right for me) then they’re onto a winner.

      On another point Gerard, I’m interested if you’ve spotted the new 11 speed Etap rear mech WITH clutch that SRAM have released. With a cage change or hanger extender, I’d think that would allow those of us with 11 speed gravel bikes to go cableless and have a 2 wheelset setup without chain issues etc. For me, I use the 3T 9-32 for road and 10-42 or 11-40 off-road and it works great for mechanical SRAM. But I hate double tap! Thanks

              I’m going to give it a go as I have full etap on my Strada currently, with a chain catcher mounted using the lowest bottle cage mount, so if I can get it to work with a 42t (possibly using a Garabuk cage) then I’ll move it to the gravel bike and go 12 or 13 speed for the Strada – more excuses for new parts!!

      It will require a little bit of tinkering to get the one chain length to work, but should be doable. With the 9-36 and the 9-42 it is definitely doable, and 9-42 is so much range that it might be a way to go. But it would be nice to get that 44T, I agree.

    It’s great that Campag has launched a 1×13 groupset, and I agree that 13 speeds give you great compromise between closely spaced gears and range. However, Rotor has a 1×13 groupset on the market since 2018/2019 (I think it became widely available in 2019), any reason you didn’t mention their release on this blog when they were released? They offer even more cassette options (10-36, 10-39, 10-46 and 10-52).

        (I have never tried any of their groupsets given that bikes equipped with Rotor groupsets are rare as hen’s teeth. But I have tried bikes with their cranks and they were pretty good.) Personally, I was hoping that Rotor, as an underdog, gains a little traction to put pressure on the two big boys to release 13-speed groupsets.

          It is actually quite terrible, or should I say, not at the same level the usual players are today. There’s very little feedback on the levers and the indexing is at the RD, this makes over or undershifting a quite common event, which in turn results in the chain being sent all over the place, especially when shifting in a rush. On top of that precision in gereral is a bit lacking, even when nailing the lever stroke.

          Also, Rotor’s cassete is wider than Campag’s and that amounts to a fair amount of cross chain and even noise very often. Not a fan either.

        Contemplating on this build for the Exploro race (great looking bike!) however also think a dedicated road-oriented/flatlander cassette would be a much needed addition. Something like a 10-33 would be great for that with the first 8 cogs being single step.
        Currently it seems that there really is a “missing” gear between 6-7th cog esp. when cruising around 35kmh (+ or – 5 kmh depending wind conditions would push you in this big gap) no matter what chainring 38-44 (would that even fit the racemax?) all give this issue at some point.

          Well, the range from 38T to 44T is much bigger than the range from the 6th to the 7th cog (14T to 16T). So mathematically it can’t really be true that you need that 15T cog no matter what chainring you choose.

          At any rate, I don’t think a flatlander is a “much needed addition” the way Campagnolo looks at it. It’s a niche of a niche and one where a gazillion options already exist, especially when one could also think that many flatlanders don’t need a clutch, and so a Campy Chorus 2×12 rear derailleur with a normal 12-speed cassette would work. But I’m not Campy (although I am a flatlander).

    The Ekar looks to be a nice addition to the 1x options out there, no two words about it. However, I can’t help but feel a bit disappointed. Even with the huge 13 speed budget, some of the gearing options are downright puzzling (like those consecutive 20% jumps in the 9-42 cassette). Is it really necessary to have six 1-tooth jumps at the top end, on a gravel bike? There may be riders who need that, but I think the majority would prefer a more consistent behavior in the climbing gears. The 9-36 seems to be a better choice in this regard, but it offers little over what was already there. I’m really curious what Shimano’s response would be, and whether we’ll have to wait till 2022 to find out…

    1. Gerard Vroomen says:

      24 September 2020

      hi Nikolay, I don’t really see your logic. You don’t like the 9-42 because the steps are too big (though better than any other cassette with that range) and you don’t like the cassette that has beautifully small steps because it offers little over what is there already. The 9-36T cassette has the range in line with the 11-42 and 10-42 cassettes, but with vastly smaller steps. In 12-speed, there is not a single cassette in that 400%-ish range. So it offers something completely different from what is there already. The 10-42 and 11-42 cassettes start with 2-tooth steps and then it gets bigger from there, that’s a vast difference to a cassette that starts with six 1-tooth steps and then has three 2-tooth steps. In my opinion anyway.

        Gerard, I’m not saying this is a bad product. What I pointed out is that there are some choices in the cassette spacing that seem suboptimal to me. It’s a matter of personal preference after all, what suits my tastes best does not have to appeal to everyone.

        I do not say that the 9-36t cassette is flawed or redundant in some way. It’s just that a 9-10-11-12-13-15-17-19-21-24-28-32-36 combination has lower dispersion and a better progression in the last three transitions. Or the 10-36 portion was patented by SRAM, who knows.

        Similarly, a 10-11-12-13-15-17-19-22-25-29-33-38-44 has much better dispersion and exactly the same low/high gears, without that nasty 23% jump between 26 and 32t.

        In both cases, Campagnolo did prioritize higher count of consecutive cogs instead of more even spacing in the climbing gears. As I originally stated, some riders may prefer it this way, some the other. I’m just pointing out what I think would have worked better for me.

        Thanks for your reply!

          There’s no patent on the sequencing, that I do know. I think the thought is more with teh 9-36 that if you are on your second-smallest gear and you need to go one smaller, you really need something smaller. So it’s not so much a 9-36 with big spacing in the end, it’s more like a 9-34T cassette and then you think “do I really need similar small steps for my two smallest gears, or do I consider I am already in trouble and anything that can keep me rolling is a good thing. One assumes you’re in control and the climb just gets a little bit tougher, then of course small steps are great. The other assumes you’re in trouble and you would sacrifice precision for a bigger chance to keep riding instead of walking. As you say, it’s personal, but I know I’m in the latter category 🙂

          Agreed about that 26-32 jump! I would have thrown in some Andy Hampsten approved odd-numbered sprockets:

            Funny you mention that. I suggested that too a while ago, but a 7t jump is a problem.

    nice piece of evolution….what kind of freehub is that ? for sure a another proprietary from Campy…

      It’s N3W, a new Campy freehub as of course a 9T wouldn’t fit any other way. But it’s retrofittable on many wheels including our current generation Discus and DiscusPlus. So not that big of a deal.

    Wow!! That’s sounds like a dream group set! I also have a question, do you need a specific crankset and chain ring to make it work with 1×13? Thanks,

      Yes, you need a special chainring because the chain is thinner. There is one coming for the Torno soon.

        Campy N3W, which can also be gotten as a retrofit on existing 3T Discus and Discuplus (available before the end of the year) and of course going forward.

    Thanks for sharing, would the 40 or 44t Torno chainring be compatible with the Ekar chain? Also wondering what caliper size/adapter is correct for the Strada pro? (Prefer 160).

      Special 13-speed rings are coming. BTW 44×9 would be an enormous gear, like 54×11 so really for time trial world championships.

        Thanks, yes was considering the 10-44 with 44 t. 9-36 with 40t looks good, but a little sceptical to 9t friction wise. 10-38 would be perfect for my use I think.

          with the 10-44 it makes sense. And I wouldn’t be so skeptical about the 9T either. But of course you need to try for yourself.

        54×11 is pretty normal for crit racing. TT is moving to 56, 58 or even bigger (less friction loss).

        Do you have any info btw how the 9 and 10T perform? SRAMs 10T was quite a fail in this regards, which is why it’s disabled by WT teams.

          Chain drives suffer from chordal action or polygon effect, which is more noticeable as sprockets get smaller. It becomes hard to form an accurate circle with less than 16 teeth and this link – http://blog.habasit.com/2017/06/what-is-chordal-action-or-the-polygon-effect/ – suggests not using less than 12 tooth sprockets for conveyor belts.
          Or, to put it another way, in these days of “marginal gains”, I don’t think anyone will try to break the hour record with a 9 or 10 tooth sprocket.

            I mean actual data, not some general blahblah.

            How many watts do I lose at 300 or 400W, that’s all I’m interested in. 1, 5, 10, 20 or even more?

                Thanks a lot, Gerard.

                I truely wish Campy would be on top of things here and blow the other players out of the water (and I say that as a forever-Shimano-fan).

                This group looks fantastic and I hope it will be a big success for them.

                I see a lot is made about teams not using the AXS 10-tooth cog. I came across this article published by SRAM. From your experience do you think their conclusion seems reasonable? They are saying 0.87% drivetrain loss using the same components.

                  One other thing to consider is that there are also many other effects. One is that starting with a smaller first cog means you can space your gears more closely in the middle. Hence you can find a gear better matching your preferred cadence there. What is the gain/loss of that? Plus the way SRAM has set up their pro teams, with the 10T being an overdrive, it means that often the SRAM rider and Shimano rider are both in the 11T, so then there is no difference in cog efficiency. and the SRAM rider has the advantage of a better chainline since his/her 11T is the second cog, not the first.

                  In the end it is very difficult to do a true apples to apples comparison, even that SRAM article doesn’t look at everything.

            The blog you mention refers to standard engineering principles for industrial setups, which is somewhat comparable to a track bike (i.e. an hour record). On a derailleur system there is already a ton of chain movement while at the same time in road and gravel applications, the propulsion is nowhere near constant (engineering school will also teach you that a motor with just 2 pistons is far from ideal, but that’s what evolution gave us). And BTW,a much bigger effect than losing a couple of teeth on the cog.

              It is true that bicycle drivetrains ignore general engineering principles in more ways than one and Moulton, for instance, have been using 9 tooth sprockets for decades. Per Marc vdW’s point though, it is interesting that World Tour teams eschew use of SRAM’s 10T cog.

                WT teams eschew modern technology in general. Took some teams 10 years to start using aero wheels, 20 to use power meters, etc. Old school mechanics run most WT teams, still pumping up tires to 12 bars if they could (and of course still tubulars in most cases. If resistance of any type was top of mind for them, they obviously wouldn’t).

                  I agree regarding the conservative approach of World Tour teams in general, with Contador’s mechanic, in particular, coming to mind. However, and ironically, oversize derailleur jockey wheels have seen pretty wide adoption, even if they don’t stand to save anything like the same watts that a larger drive sprocket could.

            It is many years now since tooth profile in bicicle transmissions features variable pressure angle by means of variable radii, with the intenth of both favouring shifting and avoiding chordal action.
