Wolf Tooth

GC49 Giant Cog 49t and 18t for SRAM NX 11-Speed Cassettes

The Wolf Tooth GC 49 Cassette Extender Cogs allow you to modify your 11-speed SRAM NX or Sunrace 11-42T 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 SRAM NX/Sunrace cassettes. To even out the gear range a replacement 18t cassette cog is also included.

• Includes 18T cassette cog for optimal gearing in the smaller cogs. 
• GC49 features 7 shift gates for faster shifting. 
• Compatible with SRAM NX and SunRace 11-speed cassettes 
• Not compatible with XD-style or Shimano cassettes
