The Mavic 2018 Cosmic Pro Carbon SL UST Wheelset is the newest addition to the Cosmic line of aerodynamic high-performance road wheels. Featuring a full carbon 40mm deep NACA profile rim, these rims boast a 25mm width that pairs perfectly with the wider tires of today, resulting in a more comfortable ride with better handling in all conditions. This ultralight wheelset boasts a total weight of just 1,450 grams, with the lightest rim in its class weighing in at just 450g per rim. While these rims are super light and aerodynamically optimized, Mavic had to revisit the brake track to ensure it stopped as efficiently as it accelerated. Benefitting from their iTgMax Carbon technology, the Cosmic Pro Carbon SL UST sheds heat reliably, while the laser-treated track provides reliable performance mile after mile.

With their UST technology, Mavic seeks to make a tubeless setup that is not only more convenient, but also capable of flat-out racing. Coming paired with their Yksion Pro UST Tires and tubeless tape, this wheelset has everything needed to experience cushy, efficient, and grippy tubeless riding.

The Mavic 2018 Cosmic Pro Carbon SL UST Wheelset comes with Mavic tire sealant, tubeless rim tape, multifunction adjustment wrench, carbon brake pads, UST Valve and accessories, dual BR601 quick release skewers, and the user guide.


Features:

  • 40mm deep wind tunnel tested NACA profile rim.
  • 25mm external width offers perfect tire integration for superior handling in all conditions.
  • Superlight wheelset weighs in at 1,450g, with a leading rim weight of 450g.
  • Best in Class braking from the iTgMax carbon technology's superior heat resistance.
  • Laser-treated single carbon layer rim bed gives predictable braking in all weather.
  • Instant Drive 360 Freewheel is compatible with 10/11-speed Shimano or SRAM drivetrains.
  • Thru Axle: Not compatible. Dual quick release.
  • Includes Mavic Yksion Pro UST Tubeless Ready 700x25c tires.

Overall very nice

Overall very nice wheelset.

Pros

Fast, light, comfortable.

Cons

Noisy Freehub (I prefer stealth)

Noisy Braking

Tires didn't last long.

Actually Mavic's hubris in forcing you to buy their semi-lame and overpriced tires to get their wheels is kind of impressive.

Great all-around wheelset

I've been on these now for about 600 miles. They are a replacement for a very good set of wheels I hated to part with. I had high expectations.

Observations so far

- Comfortable, Likely mostly due to the 25mm tires but I feel like they are more vertically compliant than other carbon wheels I tested.

- Great lateral stiffness. Power is there the moment I start a sprint.

- Breaking is much better than expected. Significantly better them my older carbon wheelset.

- Freehub has a little more friction then I'd like but it has loosened up over time. I'm sure this is due to a good weather seal which is not a bad thing.

- Easy hub maintenance.

- Breaking hard is very loud.

- Spin-up is fast and fell light.

- Hard to tell without serious test equipment but they feel fast for a 40mm profile. In any case, this is a good profile compromise.

- Tubeless mounted easily with a floor pump

So far I consider these a super value especially when you include tires. I put the Included tires on another bike and some Schwalbe pro 1 tubeless on these. Excellent combo. however, the Mavic tires are much better then I expected and I would not hesitate to run them on this race bike.

Made the transition from tubular to tubeless, and don't regret it at all.

Finally got tired of the hassles of a tubular setup....gluing tires and all that. I had recently switched the wife's bike to tubeless and she agreed it worked as advertised.....a smoother, easier, more comfortable ride at lower psi. This wheelset delivers the same in a high-performance package. It's turnkey, includes everything you need....wheels, tires, sealant, valve stems, & brake pads. And they look good, to boot.

So far, I've put about 400 miles on them and have been very pleased. I run them at 80psi (about the max recommended pressure) and they're smooth, fast and comfortable. They take the edge off of chipseal and other rough surfaces. Bearingshub have a smooth, solid feel. Handling feels as good or better than my tubulars did (note that this is a wider tire, 25mm, vs. a 22mm tubular, so not applesapples).

Too early to tell about tire life and flat resistance, but so far I'm pleased and would recommend.
