Ultima Carbon 3K DISC - Rim Brake Version

Pure Speed

WARNING:  DISC wheels are FAST!

The Ultima 3K DISC has a single design purpose, to enable you to ride faster for longer, using less energy.

To achieve this we focused on 3 key design elements.

1. Power Transfer: Underneath the perfectly laid 3K carbon skin 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 SL DISC increases the effects of inertia (momentum) as your speed increases. This means it takes less energy to maintain high speeds.

3. Advanced Aerodynamics: SL DISC outer shape is designed using high tech computer program to create what we term, an "Aerodynamically Accurate" profile.

Technically Advanced Engineering:

It's what's on the inside that counts.

More than 3 years of R&D went into the design and construction of our DISC wheels. The technology hidden underneath the perfectly laid 3K and 12K carbon sheets blows my mind every time I see it. The prototype images you see here gives you a glimpse of what lies underneath the surface and a better understanding of why these DISC wheels are so dynamically efficient and effective.

Radiating out from the central carbon core are 8 I-Beam styled carbon supports which are in turn attached to the outer rim. This system has been engineered to optimize power transfer and structural strength while at the same time eliminating unwanted weight. Part of this weight loss plan includes the use of (what our composite engineers call) "structure" foam. The structural foam core is incorporated into the carbon layers, providing additional strength and support to key areas of the wheels design while minimizing weight gain.
