Shimano 105
Shimano 105 R7100 12-speed, in Di2 and mechanical: shift levers, derailleurs, cranksets, cassettes and chains.
Gravel racing does not happen on one surface, so we did not build one tire. The Protocol lineup offers directional tread architecture, each tuned for different conditions. Same casing, same compound. The difference is what happens where the rubber meets the ground.
