Compatible cassettes:
The Wolf Tooth Components GC cassette cog is available in three versions, one for Shimano 10 speed cassettes, one for SRAM cassettes, and one for Shimano 11 speed cassettes. They are 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
SRAM 10 Speed GC:
- PG 1030, 1050, and 1070 - 11-36t and 12-36t cassettes
- X0 11-36t(XG - 1080) - Remove the 14t rather than the 17t
11 speed Giant Cogs:
- 45T GC Cog for Shimano 11-speed - compatible with Shimano 11-40t or 11-42t cassettes
- 49T GC Cog Shimano 11-speed - compatible with Shimano 11-42t or 11-46t
- 49T GC Cog for SRAM and SunRace 11-speed - compatible with Sunrace CSMX8 11-42 and SRAM PG-1130
Wheel compatibility:
Compatible with all wheels that we have tested except first generation Crank Brothers Cobalt and Iodine wheels.
Notes on 10 Speed GCs
- We have chosen to make separate cogs for Shimano and SRAM 10 speed for two reasons: 1) we design each one for the best possible shifting performance instead of a compromise on both and 2) installation is simplified because no extra spacers are needed.
- Note on the longer B-screw for 10 speed GC setups: We have found it is almost never needed with SRAM derailleurs and only needed for about 50% of Shimano derailleurs. We have added it as a separate item in our accessories category. If you think you might need the longer screw, order one separately or just go to you local hardware store and pick up an M4 x 25 socked head cap screw.
- For Shimano GC setups we STRONGLY recommend the Goatlink if you have a compatible rear derailleur (compatibility details on the product page).
General notes on GCs
- It is possible that you will need a longer chain than what is presently on your bike. Make sure that when shifted to the 42T (or 40T) cog, there is still some amount of forward travel possible with the rear derailleur cage. This is especially important on bikes with rear suspension. We have tested with Shimano, KMC & SRAM chains – all function well.
- Caution: always check full suspension travel with the chain on the GC Cog. Bleed air from rear shock and fully compress the rear suspension to check. Derailleur cage must not bottom out in forward rotation.
