Cosmic Pro Carbon wheels have long been a leader in maximizing performance and value, especially in the realm of aero speed. New innovations have made it more of an all-rounder, and this UST tubeless disc-brake version delivers incredible all-around performance at a light weight (1650g) and a price that can't be beat. Engineered with Mavic UST technology, the Cosmic Pro Carbon UST Disc offers all the benefits of tubeless, including less rolling resistance, a smoother ride quality and a reduced risk of flats. The 45mm deep rims are NACA compliant for low drag and excellent crosswind stability, and their lighter weight results in reduced inertia for explosive acceleration and climbing efficiency. The wheels are engineered specifically for disc brakes, with an optimized spoke count and lacing. The Cosmic Pro Carbon UST is completed with 25mm Yksion Pro UST tires for maximum rolling efficiency, grip and a smooth, comfortable ride.

Cosmic Pro Carbon UST Disc is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Cosmic Pro UST Disc eBikemotion X35 Hub Edition My Cosmic Pro Mavik wheels are a hybrid born of a collaboration between MAVIC and a Spanish Bike manufacturer for introduction of their pedal assist 2019 high end electric road bike to the North American market these being an upgrade and a component of the bikes Limited Edition. Rim styling is minimalist with virtually no graphics for a sleek, extreme stealth look. Designed to pare with MAVIC's tubeless UST tire the wheel/tire is marketed as an integrated system. Ride handling overall is what I expected from a well built, solid, mid level priced carbon wheel set but lacks the snap and quick acceleration you get from a competitors wheelsets at a much higher price point of course so it's a trade off. I am a fitness, performance cyclist so this is not a deal breaker by any means. The wheelset will come with a tube installed, get rid of it immediately. Included are valve stems with all the small parts, valve stem, rubber gasket, etc., necessary to run the wheel tubeless as MAVIC designed the system to be. I have to add that as MAVIC claims mounting the tire, unlike any other tubeless tire I have struggled to get on and off a rim, is by far the easiest I've ever experienced managing it without soaping the rim, a tire lever, a bruised knuckles. Tire took air after a few quick strokes of my standard floor pump and seated securely. I waited about 2 days to add sealant and over that time lost a mere 5 psi. So far so good. Regards how the tire holds up over time is another review and will follow up after the first 1000 miles for an update. I'm happy so far. Just for a point of interest I've added a photos of what rear wheel looks like built around the ebikemotion motorized hub.
