Shimano RS520 12V 50/34 Crankset - 172.5

The Shimano RS520 12V 50/34 cranks have been developed to work in conjunction with Hyperglide plus 12-speed chains to increase contact and provide greater efficiency and improved power transfer. The 2-piece design bottom bracket bearings are spaced further apart, allowing the use of larger bearings and a larger axle diameter.

It can be used with Shimano external or press fit bottom brackets. The system allows for easier installation, adjustment and maintenance.

The anodised aluminium chainrings are lightweight for smooth and precise shifting.
