INSTRUCTIONS

Mount the OneUp 45T first and reinstall all sprockets except the stock 17T and 19T sprockets (these are replaced with our 18T and aluminum spacer). Due to the large pulley wheel offset of the latest 11 speed Shimano rear derailleurs, B-Screw adjustment is well within the normal operating range and chain wrap is excellent throughout the cassette for flawless wide range shifting. The conversion keeps the 40T as the smallest aluminum sprocket for maximum cassette durability.
