1x Drivechains are everywhere you look this season from complete bikes to winning enduro rigs. Everyone is doing it so why should you have to miss out? With the e*13 expander cog you don't have to.

Q: Can I use the 40t expander cog with a 36t cassette A: We don’t recommend using the 40t expander cog with a 36t cassette. Shift performance will be compromised as the timing will not be correct.

Q: Can I use the 42t expander cog on my 34t cassette? A: The 42t expander cog WILL NOT work with 34t max cassettes. A 6 tooth jump is the maximum for good shifts.

Q: I have a short cage dérailleur on my bike. Will that work? A: We recommend a medium or long cage dérailleur

Q: Why do you only have a 42t expander cog for SRAM cassettes A: The 40t is available only for Shimano as SRAM is not offering a 34t cassette.

Q: Is it hard to setup the expander cog? A: It’s really not too hard, but you are working at the extreme limits of your rear dérailleur. If you have specific questions about the setup and adjustment, we recommend heading to your local bike shop.

Q: I have a really worn drivetrain. Will the expander cog work ok on my bike? A: Old drivetrain components could cause poor shifting performance. We recommend a new chain and a new or well-cared for cassette.
