Details
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.

Hidden technology – Weight is only part of the equation. Durability, aerodynamics, stiffness and strength are all important in wheel selection. Rolf Prima uses patented design technologies to give superior performance:
• Differentiated Flange DiameterTM – Transmits drive torque in the rear wheel across both flanges to increase the number of torque absorbing spokes
• Dish Reducing DesignTM – Increases the bracing angle of the drive side spokes to improve stiffness
• Jacked Nipple DesignTM – Moves the spoke bend away from the high stress areas increasing spoke life
• Self Aligning NippleTM – Allows the nipple to rotate in a ball and socket configuration to minimise bending in the spokes to increase spoke life
Aerodynamics – saving you time and energy
Rolf Prima wheels can save you significant time and energy over the wheels you are currently riding.
The patented paired spoke technology enables lower spoke counts that significantly improve the aerodynamics of any rim profile. In addition Rolf Prima has combined all of its patented technologies and countless hours of wind tunnel testing to create wheels that generate significantly less drag than other leading wheel manufacturers.
