OneUp Cassette Expander Cog Kit
The OneUp 45T Sprocket expands a 11-40 cassette by 12.5% speed drivetrain. Go ahead and change to a 34 tooth up front and re-gain some low speed. Compatible with 1x and 2x drivetrains, the OneUp 45T Sprocket easily installs to your XT or XTR cassette (not compatible with all 11-speed cassettes) To install, you simply remove the 18T cog and 1 cassette spacer from your freehub to make room to slide this giant cog on -better yet, the OneUp 45T Sprocket now ships with a 18T cog to replace both 17T and 19T to provide more even cassette progression which results in a smoother cadence with improved shifting.
