Shimano 105 R7100 Mechanical Road Groupset Description:

Build up a highly capable road machine with Shimano's mid-range 105 Groupset and have some cash left over for other upgrades. 105 has long been the workhorse in Shimano's lineup that perfectly balances performance and value. Crisp shifting across the wide range cassette aid in climbing the steepest hills and pedaling the fastest descents while the hydraulic disc brakes offer reliable stopping power in all conditions. Whether it's your first build or upgrading a favorite frame, the 105 Groupset should not be overlooked.
