GC49/Extended Cage XT M8000 SGS
The
Wolf Tooth GC 49 Cassette Extender Cogs allow you to modify your
11-speed Shimano cassette to create an ultra-wide range 11T-49T cassette. To retain the same shifting quality as the stock gear range, the
Wolf Tooth Giant Cog 49s have a tooth profile that is optimized for Shimano cassettes. To even out the gear range a replacement 18t cassette cog is also included.
To get the
Shimano XT M8000 SGS Rear Derailleur (long cage) to work with the
Wolf Tooth GC49 and your newly widened 11-49t gear range you will need to replace the derailleur cage with the included
Wolf Cage and pulley.
Wolf Tooth has a complete step by step instruction and compatibility guide for the
Giant Cog here- Includes 18T cassette cog for optimal gearing in the smaller cogs.
- GC49 features 7 shift gates for faster shifting.
- Compatible with Shimano 11-42t and 11-46t 11-speed cassettes
- Not compatible with SRAM XD-style or NX cassettes
