Will this work on my bike?
See our infographic for help choosing an upgrade kit for your bike.
Does this include a crankset and/or chainring?
No. You may be able to use the crankset or chainring on your existing bike. See our upgrade kit infographic for more information.
Do I need to replace my chain when I replace the cassette?
Use a chain wear tool to check the wear on your chain. If the chain is more than 0.5% worn it is recommendable to replace the chain as it will accelerate the wear on the cassette
