SRAM PG830 8 Speed MTB Cassette Cassettes
  • £16.49
  • RRP £17.00
  • Saving you £3

The cassette sprocket ratio has the same gear range as most modern 9 and 10-Speed drivetrains, but generally as there are fewer sprockets on an 8-Speed cassette, many believe shifting is not as smooth. However, SRAM designed this cassette with optimised 'shift-gates' and 'shift ramps' so that shifting efficiency and accuracy is excellent and top-performing across the entire cassette.

e.thirteen Cassette Range Expander Cog Cassettes
  • £16.99
  • RRP £54.95
  • Saving you £69

Simply fit this sprocket to your existing 10 speedd cassette, using the clear instructions provided, and say goodbye to your front shift setup. See the compatibility chart here Click here to enlarge 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.
