SRAM Rise 60 Carbon Boost Rear WheelThis rear wheel features a stiff carbon rim construction, which allows cross-country (XC) and mountain bike (MTB) trail-riders to benefit from its superior strength to weight ratio. Its carbon build also means that climbing is made easier, plus when it’s time to descend you’ll not have to worry about any unnecessary grams holding you back. Built for speed, this Boost-spaced rear wheel is equipped with 24 Sapim CX-Ray, double-crossed spokes and SRAM’s Double Time ratchet mechanism. This makes it a perfect combination for riders who want low inertia and explosive acceleration, whether it’s on a training session or race day.Hookless XC RimBuilding on a legacy of wheel technology for serious XC and trail riders, the Rise 60 – 650B wheel delivers unparalleled speed and pedalling efficiency. The hook-less rim design results in a wheel that’s lighter, stronger and more resistant to the impact of XC racing. A Double Time ratchet mechanism and a new pawl geometry integrate seamlessly with any ride for a frictionless experience on the trail. And from a branded sticker kit you can always customise Rise to the way you want to ride.
