Mountain Bike Aluminium Wheel
Set It and Forget It
Equally at home on long climbs, fast chutes and endless flow. This do-it-all wheelset was designed from the ground up by a development and production team that would live on the trail if only they could.
It may not look like your average MTB wheel, but fear not. This wheel is built to rip. Paired-spoke technology allows reduced weight while maintaining a balanced stiffness and durable ride – features more important on the trail than in any other environment. Trust our certainty guarantee and give it go. You’ll never look back.
Updated to our new 30mm internal width to maximize the advantages of modern wide tire widths, it also features an asymmetric (ASYM) rim design which improves the tension balance by up to 30%! The Tubeless Easy rim design ships with tape and valves included and allows easy home tubeless tire installation with just a floor pump.
These bomber rims are paired to our USA made XST hub platform with titanium freehub body and long-lasting, fast-spinning Enduro bearings. Like all Rolf Prima wheels, they’re built by hand right here in Oregon.
Pick a line and nail it with the newest iteration of this killer mountain bike wheel. It’s stronger, faster and stiffer than ever.
