Rolf Prima Ralos XR 29” Wheelset

The Ralos XR delivers the same top-tier performance as the Ralos, but at a friendlier price point. Built around Rolf Prima’s paired spoking technology, the Ralos XR brings spokes to the rim in pairs to neutralize the left and right outward pulling forces, allowing true wheels to be built on lighter rims with less spokes. Fewer spokes and lighter rims is the recipe for a faster rolling, more aerodynamic wheel.

Of course the heart and soul of the Ralos XR 29 is Rolf Prima’s proprietary XR hubs that are designed in the USA. The rear hub employs Differential Flange Diameter Technology, featuring Rolf Prima’s patented oversized non-drive spokes, resulting in an increase in the number of torque absorbing spokes. Meanwhile, the patented Dish Reducing Design increases the bracing angle of the drive side spokes to improve wheel stiffness for better power transfer. Black, CNC machined hub shells with alloy front-steel rear axles and sealed cartridge bearings further enhance the strength, stiffness and reliability, while bringing disc brake compatibility to your pair of circles. The forged alloy freehub body has 3 independently driven hardened steel pawls, keeping the system strong, simple and dependable.

Rolf Prima worked with Stan’s No tubes in order to create a 24.5mm wide rim that uses BST tubeless technology, allowing you to run a full blown tubeless set-up. Faster, lighter, stiffer and no pinch flats? The Ralos XR is certain to have Cross Country riders licking their chops for race-day domination.
