Extended range aluminum 40t or 42t cogs to fit either Shimano/SRAM 10-speed cassettes
- 42t is compatible with 36t max cassettes while 40t is compatible with 34t max cassettes
- Remove the existing 17t and add the Extended Range cog without any additional spacers to create an 11-40t, or 11-42 10-speed cassette option
- Cogs come with a longer replacement B-limit screw, to avoid running the derailleur with the stock screw maxed out
- 40t is available only for Shimano as SRAM is not offering a 34t cassette
- Intended for use with single chainring drivetrains chainwrap capacity will be an issue for those wanting to use double cranksets
