OneUp 10 speed Cassette Expander Cog Kit

The OneUp 40/42T Sprocket is a cost effective way to extend the gear range on your 10-speed drivetrain. Compatible with both 1x and 2x drivetrains, the OneUp 40/42T Sprocket easily installs to your 11-36T or 12-36T cassette (not compatible with all 10-speed cassettes; see below for details). To install, you simply remove the 17T cog and 1 cassette spacer from your freehub to make room to slide this giant cog on €“better yet, the OneUp 40/42T Sprocket now ships with a 16T cog to replace both 15T and 17T to provide more even cassette progression which results in a smoother cadence with improved shifting.
