40mm deep hookless carbon rims hit the ideal balance of aerodynamic performance and crosswind stability. A broad 22.4mm inner rim width supports a rounder tire profile and helps create a more seamless interface between tire and rim, reducing drag while improving grip and handling in all conditions.
From big climbs to sweeping corners at speed, the Ultra 40 is built for real-world riding. Its aerodynamic shaping, stiffness-to-weight ratio, and direct power transfer offer elite riders a wheel that performs at the highest level—no matter the route or intensity.
CADEX Super Aero carbon spokes, optimized carbon rim layup and an exclusive lacing pattern deliver outstanding lateral and transmission stiffness for responsive acceleration and consistent performance across variable terrain. The traditionally-spoked aero hub and ultra-low friction ceramic bearings are also easily serviceable.
From race day to Strava segment hunting, this is our high-performance, all-rounder WheelSystem for every road riding ambition. A balanced 40mm rim depth helps you conquer climbs, hammer flats, and rail descents with equal effectiveness—so you’re always on it from the first mile to the last.
