Mavic Cosmic SL 65 Disc Wheelset Centerlock, HG, 12x100/12x142

What Our Gearhead(R) Experts Are Saying: "I've raced the Cosmic SL 65 Disc wheelset in flat crits and long solo TT efforts, and it absolutely rips. The 65mm depth holds speed incredibly well, and the tubeless setup is the easiest I've used. It's surprisingly stable in crosswinds for such a deep wheel, and the Infinity hub platform makes power transfer feel direct and responsive."For riders chasing watts and watching seconds, the Mavic Cosmic SL 65 Disc wheelset brings aerodynamic advantage to every flat-out effort. Whether we're racing triathlons, time trials, or holding steady in a windy road race, this deep-section carbon wheelset keeps us moving fast and confident when the margins are tight. The 65mm deep rims feature a refined aero profile shaped through extensive wind tunnel testing to cut drag while maintaining stability in crosswinds. With an external width of 26mm, the rims pair seamlessly with 25mm tires for a smoother, more efficient interface. Flat spokes and a redesigned rim bed trim 80 grams off the previous model while improving tubeless tire installation. Mavic's updated UST Road tubeless system adds grip, lowers rolling resistance, and reduces puncture risk, while the Infinity hub platform and Instant Drive 360 freehub provide lightning-quick engagement and power transfer.
