  • Extended range aluminum 42t cog to fit Sram 10-speed cassettes

  • Remove the existing 17t and add the Extended Range cog without any additional spacers to create an 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
  • Intended for use with 1x drivetrains. Chainwrap capacity will be an issue for those wanting to use double cranksets
