Mavic Cosmic Carbone SLE aero wheels and tyres review
Mavic’s beauties have a metal braking surface, and though the Exalith 2 coating still makes weird noises and eats pads, it’s less offensive than its first incarnation, and brake feel is very good.
Highs: Braking, looks, quality hubs
Lows: Poor in crosswinds, pad wear
With the ‘Wheel Tyre System’ come boots and tubes as well as Exalith-specific pads. But looks and braking aside, the Cosmics simply don’t impress that much on the road.
There’s no shortage of straight-line speed, and an acceptable trade-off between comfort and stiffness, but the slim, pointy rim section is a poor performer when the going gets gusty, and for the price they aren’t light.
