Wolf Tooth Components 40T GC cog for Shimano 11-36 10sp Cassettes

The GC line of cassette extender cogs allows you to modify your 10-speed cassette into a wide range cassette. To achieve the optimal shifting, this GC is optimized for Shimano cassettes.

Compatible with the following models:

Shimano 10 Speed GC :

  • XT 11-36t (CS-M771)
  • XTR 11-36t (CS-M980)
  • SLX HG81 11-36t - Modification required (must drill out rivets holding the 17t to the larger cogs)
  • Sunrace: 11-36t cassette - note that it was not designed for this cassette but the Shimano GC does work well
