RIRO ACF Carbon Fiber Road Crankset Features and Specifications
The RIRO ACF Carbon Fiber Road Crankset is built around a 29MM spindle diameter that delivers a solid power transfer interface between your legs and the drivetrain. Ultralight carbon fiber arms keep the overall weight low while maintaining the torsional rigidity that competitive road riders demand on high-cadence efforts. Three chainring configurations — 50-34T, 52-36T, and 53-39T — let you match gearing precisely to your terrain and riding style. Full compatibility with Shimano Direct Mount systems and 110/130BCD chainrings means this crankset slots into a wide range of road groupsets without adapters. Whether you are building a race-ready setup or upgrading an existing bike, order from the official RIRO store today for the best price and fast worldwide shipping.

Stylish and weighs very little. The only downside is the instructions. But with a bit of Google you can figure it out. Perfect if you want to go down a crank size. I went from 172.5 to 165. Very satisfied.
