New: Strada Due Ultegra Di2

The world's only comfortable aero bike goes Di2

For all Shimano lovers out there, the wait is over: Starting today, the Strada Due is available with Ultegra Di2 as well. Together with the all new - Designed For Strada - Discus C45 WIDE carbon wheelset and a top-notch finishing kit, this model will go fast.

Text by Gerard Vroomen - 10 May 2019

Today, the Strada line-up is complete. After introducing the original Strada and the incredible value for money Strada Pro, we added the Strada Due for all those people who love our blend of comfort and speed but prefer a 2x drivetrain.

Earlier this year, we added SRAM Red & Force AXS eTap models, and now the final piece of the puzzle has arrived: The Strada Due Ultegra Di2. You can find out complete line-up here for the Strada and here for the Strada Due.

The main highlights of the new Strada Due Ultegra Di2 are:

Strada Due frame:

Of course, the frame is the beating heart of the bike. The Strada range started the worldwide trend towards aero bikes with bigger tires. So much so that it is now mentioned with every new aero bike that is launched. You’ll see claims like “fits big 26mm tires” or “even fits 28mm tires” left, right and center.

But that misses the point. It’s not about having enough clearance to fit these bigger tires for more comfort; what makes the Strada unique is that the entire aerodynamics of the frame is designed around bigger tires.

Aero frames are still designed around 23mm tires, so that it’s easy to score impressive numbers in the wind tunnel. But when you then plop in 28mm tires, the drag shoots up. So the tire fits but performs poorly. With the Strada & Strada Due, we say forget about those silly tires nobody wants. 28-30mm is the tire that gives you the most comfort, so let’s design the frame such that it performs the best with that tire. And amazingly (as you can for example see in the review from German magazine TOUR, unfortunately in German and in print/behind a paywall only), it is among the top performers of frames with any size tire.

Ultegra Di2 groupset

Ultegra has been the standard of affordable top performance for 20 years. And the Di2 group is no exception. It’s sophisticated, reliable, smooth-shifting and beautiful. Enough said.

3T Discus C45 WIDE wheelset

The Strada Due Ultegra Di2 comes standard with our brand-new Discus C45 WIDE wheelset. This is not just a wheelset, it is part of the Strada system. Designed specifically to work with tires that are effectively 28-30mm wide (no matter what the label says, we want the tire to MEASURE 28-30mm) and in combination with the Strada frame & fork, the C45 is super-fast.

Thanks to its Nosetail design, it provides the speed of a 60mm deep rim with a profile that is only 45mm deep. So the speed of 60mm, the confidence-inspiring crosswind manners of a 45mm rim. To learn more, check our the Discus C45 WIDE page.

Availability

The first Strada Due Ultegra Di2 bikes are in stock now. Unfortunately, due to the success of the Force AXS eTap and Red AXS eTap bikes earlier this year, we diverted some frame production to those models. So for 2019, we will have only very limited numbers of Ultegra Di2 bikes. So it’s a bit of an unintentional limited edition.

For more information and detailed specs, check our the Strada Due page. If you have any comments or questions, feel free to leave them in the comments below and we’ll answer them as quickly as we can.

    Hi – quick question. I have a size small Due (and size small seatpost) with Ultegra Di2 and the battery is hitting the lower water bottle bolt insert, preventing the battery from going completely into the seatpost and preventing me from lowering the saddle height below 68cm. I was intending to cut the seatpost, but I don’t think it will solve the problem as the battery will continue to hit the bolt insert. Any ideas? Do I need an XS seatpost without the bolt inserts? Thanks.

    Hi, just picked up an XL due, very excited by it except… I’m 6ft6 and will likely need the XXL seatpost to get my saddle height correct 860mm bb to saddle. (so 820 to rails) which would put me 17mm over the XL posts minimum insertion…
    Any idea if they’re is any stock left in drawer/squirrelled away in a dusty box/ when more will be available?/ any left over from Conner Dunne’s AQB bikes ha!

    Question: Seat post lengths in the larger sizes (L & XL). What is the max extension of the Seatpost in the large frame? My normal fit runs at 790mm from the centre BB to the rails, and the geometry of the Large looks about right. But I fear the Seatpost won’t extend enough and the resulting XL situation would give me a reach that’s too long. For reference, I am 1.86cm, but have a genuine 34” inside leg. Looking for some advice please.

      Hi Rob, if you have a genuine 34″ inseam, so 860mm, it would be strange for your saddle height to be 790mm BB-RAILS. Even for BB-top of the saddle, 790mm would be near the top end of the normal range, but to the rails it would be very strange. Are you sure? At any rate, we have an extra long post that would allow such a saddle height on the Large (but it’s a bit tall for the regular post so you just have to be sure to get the extra long post).

        Thanks for reply, if I do the book against a wall trick, then the measurement comes out at 910mm for my inside leg. (I have very long legs vs body). Also, where can I get the XL Seatpost? No-where seems to have them, even the 3T website doesn’t list them. What’s the max range of the Large Seatpost then?

          Hi Rob, ok so that’s more a 36″ inseam. You can get the XXL seat post here: https://www.3t.bike/en/spare-parts/charlie-strada-team-592.html?search_query=charlie+without&results=14#/216-level-team/371-bikes_size-xxl. Stock on all seat posts is low at the moment, we’re working to get more in.

            Thanks for your help on this, I am now the owner of an XL due and actually it all fits really well. I have an issue with a bent gear hanger which is being dealt with but otherwise, very happy. You have a guy called Eric Scaggiante working in your tech support team who has been nothing short of superbly helpful in working with me to understandthe sizing etc. Please pass on that he’s doing an outstanding job.

    Question –
    the 2019 Strada frameset – In terms of di2 , how does one know if it is compatible as a 1x (no FD) ? Do all Strada frames have holes for wires in the chainstay ? In other words, If I had ultegra di2 and wanted to insert an E-Tube battery in the seatpost/tube , could I run wires through the frame to a rear mech (only) ? what makes the 2019 (and/or 2020) frame “Di2 specific” ? is it just the bundled groupset spec’d for whole bike purchase ? Are all Stradas capable of a 1x di2 setup ?

      Hi Eric, all Stradas can route the Di2 cabling, there’s no difference between frame styles or generations.

      Hi Thomas, we have a lot of people using the Exploro for cross, the Strada clearance is so tight (by design) that I wouldn’t recommend it for cross.

    Hi,

    how long is the Strada Charlie seat post, and what are the maximum and minimum insertion depths? I’m trying to decide whether to get a size S, on which I would end up with the saddle pretty low and maybe a 120 mm stem, or XS, with the saddle a bit higher and perhaps a 140-150 stem.

    1. Gerard Vroomen says:

      Hi Rasmus, I would not base the bike size on the seatpost length. The post can be cut shorter, and there are longer posts available too. To give you an idea, the maximum saddle height of the Small frame with the Small seatpost is around 71cm, and the minimum is then around 66cm, but again with cutting it or going up to the next post you can achieve anything you want (of course these numbers depend a bit on the exact model of saddle and the seat position).

        Thank you!

        Not really trying to base the size on seatpost length, but more trying to figure out which one would fit me better. They seem to be very similar in size, with the only real difference being 2 cm extra reach and about 6 mm difference in saddle to handlebar drop, which is easy to adjust with spacers if a 2 cm longer stem, and the difference in headtube angle, won’t eliminate that difference by themselves. On my Exploro, size S, I have a 130 mm stem and the saddle height (measured from center of bottom bracket to center of saddle clamp so I guess the actual height is 3-4 cm higher) is 66 cm. Am I right when I estimate that this translates into a 120 mm stem on the S, and 140-150 on the XS?

        If I’m right, I guess it comes down to how badly I want the THM Tibia (Only available up to 120 mm), and clearance for bikepacking bags. 🙂

          Hi Rasmus,

          Actually, the S Exploro and Strada fit exactly the same if you add one more 10mm spacer to the Strada, even though stack/reach numbers may not make that exactly clear because those two numbers are inter-related. So It would be a Small with a 130mm stem or an XS with a 150mm stem, which doesn’t seem like a good idea. In fact a Medium with a 110mm would probably make more sense than an XS with a 150mm.

        Thanks again!

        Am I right then if I guess that the difference in fit between a Strada Medium with 110 mm stem and a Strada Small with 130 mm stem would be roughly 20-30 mm of spacers? In that case I’d say size M could be something for me.

        What are the lengths of the S vs the XS seatposts for the Strada?

          210mm for the XS and 250mm for the S. but of course posts can be swapped out or cut to get the length you need. But with those lengths, most customers can achieve their desired seat height straight out of the box.

              Hi Brandon, normally it does not as there is not enough space between most XS riders’ seat height and the top tube.

    Suitable for my @90kg weight and rough chipping tarmac B roads and fast 100 kph A roads and up 30 % hills in North Wales 🏴󠁧󠁢󠁷󠁬󠁳󠁿 UK 🇬🇧?

      Weight: absolutely, we test for an equivalent of 110kg
      Roads: The rougher the better, just pick the right tire (especially also in combination with your weight). It depends a lot on the rim you use, so in this particular case of the C45 rims, most 25mm tires will fit out to around 28mm, while tires labeled as 28mm will fit like a 30-32mm tire. That’s what you want in this case. More comfort, more grip, more puncture resistance.
      30% hills: The bike comes with an 11-30 cassette instead of the more common 11-28, so you have a bit smaller gear there. But 30% is tough obviously. I don’t know how strong you are but if it were me, I’d swap the crank for a subcompact crank, maybe a 46-30 ratio. That way you have a 30×30 gear, 1:1. I’m not going to say that makes a 30% grade a piece of cake, nothing does, but at least I’d have a fighting chance.

      I can’t comment on the super-steep hills part, as my Strada Pro is 1×11, but I will say that on typical B roads in middle England, with a lot of potholes and broken tarmac, the bike is very comfortable – noticably so compared with my previous ‘endurance’ bike. The accomodation of larger of tyres makes all the difference – as Gerard says, my 25mm pirelli tyres come out as 28.1 on my rims, which all adds up to more comfort. Which all leads to faster times – because if you feel comfortable, you can exploit the aerodynamics more.
