Shimano SW-RS801 Shift Switch Black, SW-RS801-S, 100mm

Whether we're mounting them on the tops or down in the drops, the Shimano SW-RS801 Shift Switch gives us multiple shifting points for our Shimano 12-speed Di2 drivetrains. This lets us focus on the road ahead without needing to reposition our hands for every shift, saving us crucial seconds in the process.
