Mavic Cosmic Carbone SLS WTS Front Wheel

The Mavic Cosmic Carbone SLS remains one of the best values in an all-purpose aero wheel. It is also one of the few factory built wheels that will reliably hold up even to 200-plus pound riders and seldom if never have to be trued.

The WTS part refers to Mavic wheel and tire system which basically means they include a Griplink front tire so you can get all the performance out of the wheel. This is more than a gimmick. We have found the Grip link really holds the road like its name implies with the perfect amount of suppleness - not too stiff or too squishy. The Griplink tire also has a nylon, puncture resistant belt making this grippy and supple tire surprisingly flat resistant.

Exceptional aerodynamics are created by a 52mm carbon/aluminum rim built with 16 bladed spokes radially laced. The hub is made with both a new aluminum axle and body with 12k carbon flanges fitted with Mavic's QRM+ bearings specifically designed for cycling. The QRM+ bearings supply legendary glass-smooth performance and can be quickly adjusted while on the bike.

The new Maxtal aluminum and 12K carbon rim has an aluminum braking surface for durability and optimal braking. There is also no need for special brake pads. The Cosmic Carbon SLS wheel is a fantastic choice for an aero wheel with a solid ride and the very high build quality Mavic wheels are known for.
