OneUp Components 18T Sprocket + Spacer [ 1x11 ]

The OneUp 18T sprocket and spacer kit replaces the 17T and 19T sprockets within a stock 11 speed Shimano cassette and spaces the cassette out by 4mm which greatly reduces back-pedal chain dropping issues. The 18T kit removes one gear from your cassette without changing the stock range and is only compatible with 11-speed components.  Simply use your low limit to remove one click from your rear shifter.
