Born on the World Cup destined for your local trails. We poured World Championship-winning engineering into developing an all-new alloy for these Control wheels. To increase the new material’s durability we customized our shot peening process—where metal projectiles are shot at the alloy to increase its strength—meeting the precise demands of our XC riders. If that wasn’t enough to eliminate creaking and reduce weight individually customized sleeves are chosen to bond every single rim. The result is a wildly over-engineered trail-ripping best-of-the-best aluminum wheel: held to the same standards as our highest-end Control SL carbon components. Whether you are looking for a solid set of training wheels that will handle it all or a big upgrade from entry level wheels Roval Control Alloy is the go-to wheel. With creak-free hoop construction that’s laced to high-performance and proven DT Swiss hubs you can tap into a wheelset born from World Cup technology that’s ready for all riders.
