Long awaited - The first mountain bike wheels from Rolf Prima. Built on the paired spoke technology, the Ralos is strong and light. Ready for XC, the Ralos comes with tape and valve for seamless tubeless compatibility. Available in 29" and 26". Working with Stans NoTubes BST technology, the Ralos is built on a 25mm wide tubeless ready rim that has been engineered for toughness and weight. The rim features internal stiffening features to yield exceptional stiffness in a light overall package. The Ralos proprietary hub is disc brake compatible and is designed and manufactured in the USA. The rear hub features Rolf Prima's Patented Differential Flange Diameter, which doubles the number of pulling spokes handling the torque loads creating a more durable wheel.
These came on a bike I bought. They have held up great so far. I do mostly AM riding, plenty of rock gardens, roots, small 12-24" drops, climbs, fast stuff etc.... I've raced a few races with them and no problems whatsoever.
