Aerodynamic carbon rear wheel with ceramic bearings for maximum performance.

The Fulcrum Speed 40 DB rear wheel was developed for demanding road cyclists who are looking for maximum aerodynamics, low weight, and ultimate efficiency. The 40 mm deep full carbon rim ensures an ideal balance of speed, stability, and control – perfect for fast road races, triathlons, or ambitious training rides.

Thanks to 2-WAY FIT technology, the wheel can be used with classic clincher tires as well as tubeless. The 19 mm inner width supports aerodynamically optimized tire profiles from approximately 23 mm width.

The high-quality USB ceramic bearings reduce friction and ensure particularly smooth rolling – a clear advantage at high speeds.

Highlights:

• 40 mm aero carbon rim: high speed with stable handling.
• USB ceramic bearings: extremely smooth-running and efficient.
• 2-WAY FIT: compatible with tubeless and clincher tires.
