Cassette options with SRAM Force1 Medium cage rear derailleur

If you want to increase the gear range of your Exploro SPEED with medium cage SRAM Force1 rear derailleur and 11-36T cassette, there are many options.

SRAM will tell you that 11-36T is as big as you can go. If you want to believe that, there are three options to still increase your range:

  1. 3T Bailout and Overdrive 9-32T cassettes have a bigger range than 11-36 (356% vs 327%)
  2. e*thirteen makes an 11-speed 9-34 cassette
  3. Leonardi has a 9-36T cassette

Because these cassettes start with a 9T cog, they all need an xD or xD-R driver. Additionally, you have to decrease your front ring by 18% to keep the same top gear. As a result, you will also get a smaller climbing gear despite the biggest cog not being any bigger than on an 11-36T cassette. So to compare:

Leonardi9-36400%Hard to find nowadays, mediocre shifting performance

 

But there is a second group of cassettes you can use to increase your range. And all you need to do is ignore what SRAM tells you about the 36T maximum cog spec for the medium cage Force 1 rear derailleur.

We’ve been testing all sorts of combinations in the lab and on the road, and we found you can use a much bigger cassette than recommended without a problem Here’s the list:.

BrandCassetteRangeNote
SRAM11-36327%Standard Exploro Speed cassette
Shimano11-40364%Use 1 linkset less than recommended (single-speed chain length method)
SRAM/Shimano11-42382%Use 1 linkset less than recommended (single-speed chain length method)
SRAM10-42420%Needs xD driver & 9% smaller chainring for same top gear. Use 1 linkset less than recommended (single-speed chain length method)

 

Why would you want to run a medium cage over a long cage? With the mid-range cassettes, a medium cage offers crisper shifting. It also gives you better ground clearance.
