Every gram counts. Thats why Rovals Control SL 29 Wheels place a strict focus on cross country racing, allowing them to create a pair of ultra light, stiff & durable wheels that are guaranteed to help reach that podium. H&-built onto exceptionally light carbon rims, the Roval Control SL 29 Wheels come set-up perfectly, straight from the box. This light carbon rim also features a Zero Bead Hook design which pairs perfectly with tubeless tyres while boosting impact resistance & overall strength. These rims are laced via DT Swiss Revolution spokes to strong, CNC machined alloy hubs featuring DT Swiss internals that serve-up lightening fast engagement combined with easy access to spares for servicing. Included with the Roval SL 29 Wheelset are 135mm & 142mm rear axle end caps, & 15mm & QR front hub end caps to fit the widest range of bikes possible without the need for size specific hubs.
