Mavic Cosmic Ultimate 45 Disc 公路碳纖維輪組-23mm-HG-R

A single full carbon spoke from one side of the rim to the other with the hub inbetween.
Perfect wheelsystem balance, lateral stiffness, and power transfer (either pedaling, braking or handling).
The shape also integrates aerodynamics and vertical compliance (comfort) in the equation.

Carbon is lighter than alloy, but weight always add up.
Using the right amount of fibers where the rim is less stressed to reduce rim weight with no compromise on reliability, this gives wheels that are livelier and more enjoyable while climbing. Up to 70g saved per rim.

With its special properties, ceramic makes bearings spin a little faster and are more durable. Together with premium ceramic material, we use premium low-density grease paired with ultra slick seals.
