hubset: Carbon TdF38-Clincher wheel systems orbit around a proprietary hub designed and manufactured in the USA. The front hub features a unique 85mm wide flange placement which increases lateral wheel stiffness by nearly 20%. Patented Differential Flange Diameter™ on the rear hub lends a mechanical advantage effectively doubling the number of functional pulling spokes; increasing wheel durability. Black, CNC machined hub shells with oversized axles provide high strength, stiffness and light weight. Optimized flange contours provide full spoke elbow support, increasing spoke life. Hubs also feature precision cartridge bearings with low drag supplementary contact seals and bearing preload adjustment on both front and rear hub shells. freehub mechanism: CNC machined Titanium freehub body has 3 sprung steel pawls for a bomb-proof torque transfer system. Pawls are driven by 3 hardened steel leaf springs. The system is strong, simple and dependable.
rims: This proprietary 38mm tall carbon fiber rim offers superior aerodynamic performance as well as excellent lateral and torsional stiffness. The CNC-machined alloy clincher brake sidewall is co-molded to the carbon rim to improve braking performance and increase durability from impact.
spoke & nipple: Black custom bladed, 14 gauge spokes and internal alloy nipples with nylon inserts contribute to clean aerodynamic performance and superior, long-term durability. Patented, Jacketed Nipple Design™ and Dish Reducing design™ reduce spoke bending loads and rear wheel dish to increase spoke fatigue life.
extras: Rolf Prima Carbon TdF38 clincher wheel systems include alloy valve extenders and titanium quick release skewers (89g / set).
