Ultima SL85 | Carbon | 1793 Grams

The SL85's have a single design purpose, to go faster for longer, using less energy. To achieve this we focused on four key design elements.

1. Power Transfer: The deeper rim section of the SL85 shortens spoke lengths, increasing torsional and lateral stiffness in the wheels, which in turn transfers power more efficiency. This means it takes less energy to generate more speed.

2. Centrifugal Force: The heavier rotational mass of the SL85's increases the effects of inertia (momentum) as your speed increases. This means it takes less energy to maintain high speeds.

3. Compliance: Optimizing wheel suspension "compliance" is the key to achieving faster rolling speeds. The smoother your wheels roll over irregularities in the roads surface, the less they bounce and faster they roll. The SL85's carbon rim was designed to provide a higher level of compliance for a smoother, faster ride.

4. Advanced Aerodynamics: SL85's outer shape were designed using high tech computer programs to create what we term, an "Aerodynamically Accurate" rim profile. There is a limit to how deep you can take a design and 85mm is the sweet spot.
