If you're converting over to a 1x drivetrain, or just need a bigger bail out gear for some super hilly trails, then you need the Wolf Tooth Components 42T add-on cog. This huge cog will give you an extra wide range that can enable you to get up and over pretty much anything in your path. To install, simple remove your cassette from the wheel, remove either the 15T or 17T cog, install the GC 42, then the rest of the cogs in the correct order. It's super easy, and lets you modify your existing cassette for a wider range.

The Wolf Tooth GC cogs are only compatible with SRAM PG 1030, 1050, and 1070 - 11-36 and 12-36 cassettes. X0 11-36t (XG - 1080) - Remove the 14t rather than the 17t
