Mavic Comete 50 Disc Brake Wheelset

The Mavic Comete 50 Disc Brake Wheelset is one of the first carbon wheels to genuinely compete on both ends of the road — flat and fast enough to time-trial, light enough at 1,315g for the pair to stay in contention on longer climbs. At 50mm deep and 23mm internally wide, the Comete 50 sits in a profile that Mavic spent multiple Geneva wind tunnel sessions refining, arriving at a rim shape designed to manage crosswind pressure rather than be destabilized by it. Every unit is hand-built at Mavic's Chavanod laboratory in the French Alps and passes through 57 separate in-house tests before it ships.

The carbon construction relies on Mavic's Adaptive Layup, a rim-build approach that combines three distinct fiber types — T700, T1000, and 3K — each contributing something specific. T700 handles impact resistance and compliance; T1000 delivers the stiffness-to-weight ratio you need when putting down hard watts; the 3K weave binds the hooked clincher architecture together. The rim is finished in UD matte clearcoat and rated 50% above UCI requirements in frontal impact testing. The spoke configuration is 21 Mavic Aero Carbon spokes per wheel: 14 in a cross-two pattern to transfer drive power under load, and 7 radial spokes for aerodynamic balance and weight savings. Mavic profiles those flat carbon spokes specifically for wind tunnel airflow — 18% less rotational drag at 50km/h compared to standard flat carbon spokes, according to their internal testing. Tension longevity is addressed by the Locked-In Spoke Head system, which mechanically secures each spoke head and keeps tension stable over the wheel's service life.

The 30mm external rim width paired with that 50mm profile produces measurable aerodynamic output. In Mavic's wind tunnel work at the CMEFE/HEPIA facility in Geneva, the Comete 50 shows 5 to 10W of savings in crosswind conditions starting at roughly 10km/h of wind at a 10–20° incidence angle. Over a 50km course, Mavic's internal testing found a gap of up to 12 seconds compared to the Cosmic SLR 45. These are manufacturer figures — real-world results vary — but the rim geometry follows a clear logic: the 23mm internal width opens a 28mm tire to its full volume, and the Mavic Aero Wide Rim / Shorter Footprint profile is shaped to reduce drag at speed, not just in still-air conditions.

At the hub, Mavic's ID360 freewheel system runs a 40-tooth ratchet, which translates to near-instant drive engagement when you accelerate out of corners or sprint. Mavic Ceramic bearings reduce friction compared to steel alternatives, and the alloy hub bodies come in lighter than the previous generation (−22g rear, −5g front). Axle standards are 12mm thru-axle front and rear — 100mm front, 142mm rear — with Centerlock disc brake interface. The wheelset ships with an HG11 driver body installed, compatible with Shimano and SRAM 11-speed cassettes; an XDR driver for SRAM 12/13-speed is also available.

Tubeless setup arrives ready to go: tubeless tape is pre-fitted, valves are included, and Mavic wheel bags are in the box. The hooked carbon clincher rim supports tires from 28mm (the recommended minimum, matched to the 23mm internal width) up to 65mm ETRTO. The Comete 50 carries an ASTM Level 1 classification, a 120kg maximum load rating, and Mavic's lifetime warranty. For riders who want a single high-performance wheelset that doesn't ask them to trade aero efficiency for climbing weight, the Comete 50 makes that case clearly.
