● Shimano 11-speed and Campagnolo 11-speed compatible thumb shifter ● Power ratchet non-index type ● Compatible with 26mm handlebars (23.8mm, 22.2mm, handlebar sleeves included) ● Compatible with Shimano 11-speed shadow RD/RD+ and Campagnolo 11-speed (right lever only) ● Weight: 80g (right), 60g (left) Power ratchet non-index type The lever has a small cam built into it that activates the ratchet function. This cam engages with the ratchet side one step at a time. There is little resistance when pulling the lever, making it easy to pull. There is resistance when returning, which stops the lever and positions the derailleur. (Note) Make sure the oval projection on the back of the black plastic washer is securely inserted into the oval hole on the shifter before tightening the crown screw. If the plastic washer is left loose when tightening, the projection will be damaged and the shifter will no longer be secured. Cannot be used with SRAM products.
