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.
Cassettes and freewheels for bikes are a cluster of sprockets in a range of sizes offering a multitude of gear ratios. The difference between the two is, a cassette slots onto the freehub, which has the ratchet built in and is then secured with a lockring, whereas a freewheel is a cluster of sprockets built around a ratchet and threads directly on to the hub. Cassettes and freewheels come in many ratios, close ratio is when the number of teeth increase in small increments of 1 or 2 at a time, whereas a wide ratio is when the teeth increase in larger increments of 3 or 4 at a time. Most systems will use a cassette hub as these allow for a wider bearing spacing and increased axle life, you can also fit a larger quantity of sprockets onto a cassette hub with 11 speed systems now becoming available. With cassettes you must use the appropriate spacing for your gear levers and rear mech, Shimano and Campagnolo are not interchangeable so you will need to match the cassette to your levers for smooth and precise shifting. Sram and Shimano chains and cassettes will work together as they use the same spacing.
