This amazing clincher uses a proprietary carbon/aluminum construction technique to deliver a high level strength-to-weight ratio and an optimal machined aluminum braking surface. The aluminum axles and the lightweight, fast-engaging titanium freehub body are two of the gram cheating details Shimano employs to keep these wheels light and fast. Double contact, low friction seals offer smooth rolling performance while straight-pull spokes increase torsional rigidity. 20-spoke rear. 860g. (QR skewers included).
