Mavic's wheelset designed and purpose built for the demands of electric mountain bikes, featuring a feast of newly developed technologies and features. Key Features - PFP (Pinch Flat Protection) rim sidewalls have a wider contact surface at the top of sidewall, which significantly minimizes the risk of tire cuts and punctures. Super strong rim (ASTM 5) gives you the confidence to push your limits on rough terrain Wider 35mm (internal) rim adds stiffness and cornering precision. Engineered for the added torque of E-bike motors with 28 threaded three-cross spokes that further boost lateral stiffness.
