Key Features

The RC50 ULTRA is a lightweight, aero road wheelset built from high-strength, high-modulus carbon fiber with a UD matte finish and ceramic-bearing hubs for low rolling resistance. Its 50 mm rim depth balances speed and crosswind stability, while the 21 mm internal / 28.5 mm external width supports modern tubeless tires with a broad, efficient profile. Stiff carbon spokes are laced 18 front / 24 rear to keep steering precise under sprint loads, and tension targets are F 100–110 kgf / R 110–120 kgf (±10%). Compatible with HG freehub bodies, the complete set weighs a feathery 1260 g (±5%), making it a sharp upgrade for climbers and all-rounders who still want deep-section speed.
