Cosmic SL 40 RB QR Wheelset + Vittoria Tire Bundle

A hilly training loop that pairs a long climb with a quick descent is where the Cosmic SL 40 RB QR Wheelset + Vittoria Tire Bundle earns its place. The Mavic Cosmic SL 40 is a carbon rim brake road wheelset with a 40mm deep rim that stays light on the climb and holds speed once the road flattens. The Vittoria Rubino Pro G2.0 tubeless road tires add a supple 150 TPI nylon casing and a 3C Graphene compound that trims rolling resistance and adds grip in corners. Both parts are tubeless-ready, so the pair can run without tubes and at lower pressure for a smoother feel on broken pavement.

What Our Gearhead® Experts Are Saying:

“A 28 on a 40mm carbon rim costs almost nothing on a long climb, and the descent is what sold me. The supple casing soaked up broken pavement before it reached my hands, and I could brake late into corners without the tire feeling vague. That is the width I would put on this wheelset for fast training.”
