From the first pedal stroke, the low weight and instant response of Enve's XC Rims will impress you. But, they're way more than just light and quick—these hoops are seriously stiff and strong, too. Enve used their years of experience to tune the carbon layup for maximum impact resistance at a feathery low weight only carbon can achieve. Enve also molds in the spoke holes so there's no drilling in the rim bed, which boosts the strength and reliability even higher. So descend as fast as you dare, then point your bike back uphill and spin away from everyone trying to hang with your amazing wheels!
