Aerodynamic carbon rear wheel with ceramic bearings for maximum performance.

The Fulcrum Speed 40 DB rear wheel was developed for demanding road cyclists seeking maximum aerodynamics, low weight, and peak efficiency. The 40 mm high full-carbon rim provides 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 both traditional clincher tires and tubeless tires. The 19 mm internal width supports aerodynamically optimized tire profiles from approximately 23 mm wide.

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

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