The Mavic Cosmic SLR 32 is the kind of wheel that makes sense the moment you start climbing. Built around 100% unidirectional carbon fibre rims and ceramic bearings, it's one of the most capable lightweight bicycle wheels available for road racing and mountain road riding.
At 1,390g for the pair, these are genuinely light bicycle wheels. Mavic's Adaptive Layup construction means carbon is distributed where stiffness is needed most, and kept minimal everywhere else. The result is a wheel that accelerates well and holds its composure on long descents, precisely the sort of thing you want when the road tilts upward and you're trying to hold a wheel in front of you.
The Mavic Cosmic SLR 32 disc uses a centrelock-only braking interface and is fully tubeless compatible via Mavic's FORE technology, which reinforces the bead seat for a reliable, sealed tubeless setup. The 32mm profile hits a useful middle ground too, aerodynamic enough for fast road riding, not so deep that a crosswind becomes a problem on exposed mountain roads.
With Cosmic SLR 32 disc wheels, Mavic has kept the freehub options broad:
- HG / M11 for Shimano HG Road 11/12-speed
- XDR for SRAM
- N3W for Campagnolo 13-speed
If you've been looking at Mavic wheels and want something that performs at the sharper end without pushing into full race-day-only territory, the Mavic Cosmic SLR 32 is well worth considering. And if you're keeping an eye out for cycling wheels on sale, it's worth checking current stock as availability moves quickly on popular builds.
