SHIMANO Shimano 105 R7100 12-Speed Double Chainset 50/34 172.5mm

Upgrade your drivetrain with the Shimano 105 R7100 12-speed double chainset. Designed for riders seeking high performance and efficiency, this crankset features a 50/34 gear ratio and 172.5mm crank arms. The lightweight construction utilizes HollowTech II technology, which uses forged and anodised aluminium to keep weight low while minimizing flex during heavy pedaling. This chainset is built to work seamlessly with Hyperglide plus 12-speed chains. The specially developed chainring teeth increase contact with the chain, resulting in smoother shifting and better power transfer to your pedals. Because of the HollowTech II design, the bottom bracket bearings can be spaced wider apart. This allows for the use of larger bearings and an increased axle diameter for improved durability and performance. Whether you use Shimano external or press-fit bottom brackets, this chainset provides a reliable and efficient solution for your road bike setup.
