* A climbing wheel with an aero advantage, designed to be ridden in the mountains and optimized for use with modern disc brake road bikes.* ENVEÛªs most versatile and consequently most popular carbon fiber aero road wheelset amongst road cyclists of all abilities. * Wider than its predecessor (29mm wide external, 21mm internal) to improve rolling resistance and improve aerodynamics for use with 25mm tires. * Road tubeless compatibility means improved rolling resistance, comfort, traction, and a reduced propensity for flat tires. * Dissimilar rim shapes and geometries between front and back wheels to maximize aerodynamic efficiency and rideability in variable weather conditions. * The front rim is 38mm deep and shallower than the rear rim to aid in cross wind stability while rear rim is 42mm deep and therefore improves overall airflow attachment. * Centerlock hubs do not include rotors
