Wolf Tooth

Giant Cog GCX XX1 Replacement Cog

Wolf Tooth's Giant GCX cog for SRAM XX1 and X01 cassettes replaces the stock 42t aluminum cog with either a 42t, 44t, and 46t cog in colors not available from the factory. 

The 44t version of the Wolf Tooth GCX reduces gearing by 5% over the 42t version. What does 5% reduction mean? The 44t cog is the equivalent of moving the front chainring down 2t when in the easy gear but you don''t pay the penalty at the top end where you might want or need a slightly taller gear. 

Installation takes only a few minutes and complete instructions can be found here.

• Fits only SRAM XX1 and X01 cassettes
• Choice of 42t, 44t, and 46t
• Made in the USA
• 93g

The Wolf Tooth GCX cog brings additional gearing and color options to your SRAM XX1 and X01 cassette.
