E*thirteen Extended Range Cog
  • 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
  • Intended for use with single chainring drivetrains. Chainwrap capacity will be an issue for those wanting to use double cranksets
