Rolf Prima brings their stellar wheel design to the dirt! The Ralos6 Wheelset features their Paired Spoke technology for high lateral stiffness, low weight and excellent aerodynamics. These wheels boast fine Rolf hubs that are CNC machined in America and roll on sealed cartridge bearings and feature Rolf's Differential Flange Diameters. Spinning around those hubs are 25mm-wide Rolf aluminum rims that are tubeless-ready thanks to Stan's NoTubes technology. They also have internal stiffening features that complement the ride of these impressive hoops.

The use of paired spokes (the left and right spokes almost meet at the rim) allows Rolf Prima spokes to neutralize the lateral force of the opposed spoke (the one on the other side). This lets Rolf Prima wheels use incredibly high spoke tension for exceptional strength, a minimal number of spokes and lighter rims. The result: strong, aerodynamic, light, great-riding wheels you'll love.
Rolf Prima wheels feature a Rolf rear hub with Differential Flange Diameters for greater strength. The higher, non-drive-side flange allows the use of shorter spokes, which helps balance the overall spoke tension. It also effectively doubles the number of pulling spokes capable of transmitting pedaling torque. The resulting wheel is stronger and stiffer for optimum reliability and pedaling efficiency.
