products – Carbon TT58
The wheelsHeather Wurtele rode to victory at IronMan St. George in May 2010. With the lowest spoke count available and deep section rims, the TT58 slices through the wind as you race the clock. Although it is designed for triathlons and time trials where aerodynamics is #1, the TT58 is light with an exceptionally low rotational weight for its rim depth; making it a wheel that climbs and accelerates. Whether it's a 25 mile or 112mile time trial, the less wind drag your wheels create, the faster you go. The TT58 is the ultimate secret weapon for race day.

Rims: Designed and reinforced for the low spoke count (10H Front, 12H Rear) and high spoke tensions, this proprietary carbon fiber rim offers superior lateral and torsional stiffness for all the power you can put into it. The 58mm deep profile combined with a narrow spoke bed significantly decreases wind drag while also minimizing rim weight. Brake sidewalls are impregnated with fiberglass for improved braking performance and durability. The combination of low spoke count, exceptional aerodynamic performance and minimal rotating weight makes the Carbon TT58 wheel system the fastest tubular wheelset available in its category.


Hubs: The TT58 rims are laced to the TdF4.4 proprietary hub, designed and manufactured in the USA. The front hub has a unique 85mm wide flange placement which increases the lateral wheel stiffness by nearly 20%. The rear hub features our Patented Differential Flange Diameter, which doubles the number of pulling spokes and creates a more durable wheel. Both hubs are fully CNC machined and feature oversized axles, increasing the wheel durability and stiffness without increasing the wheel weight. Ceramic bearing upgrade available.


Freehub: CNC machined Titanium freehub body has 3 independently sprung steel pawls for a bomb-proof torque transfer system. This system is strong, simple and dependable.


Spoke & Nipple: The TT58 wheel set features paired, 14 gauge custom bladed spokes with internal alloy nipples with nylon inserts to create a quicker accelerating, faster climbing wheel with superior, long-term durability. Self-locking thread technology ensures wheels stay true longer. Our Patented, Jacketed Nipple Design™ reduces spoke bending loads and wind drag, increasing spoke life and contributing to a more durable, stiff and aerodynamic wheel system.


Extras: Rolf Prima TT58 wheel systems include Titanium quick release skewers and valve extenders. Protect your wheels with a Rolf Prima double wheel bag.
