Shimano 105 FC-R7100

The Shimano 105 FC-R7100 crankset brings the benefits of 12-speed shifting to Shimano’s most famous "workhorse" series. Designed for enthusiasts and competitive riders who want pro-level technology without the premium price tag, the R7100 utilizes Hollowtech II construction to deliver exceptional power transfer. The arms are forged to be hollow, balancing a lightweight feel with the high rigidity required for climbing and out-of-the-saddle efforts. With a sleek, glossy black finish that echoes the design of Ultegra and Dura-Ace, it offers a high-performance look and feel while maintaining the legendary durability that the 105 name is built on.
