Fulcrum Speed DB Wheel

The 55 mm profile is designed to balance aerodynamic efficiency with handling stability. It slices through the air to maintain higher speeds on flat or rolling terrain without being overly susceptible to crosswinds.

No, the undrilled rim bed is a significant advantage because it eliminates the need for tubeless rim tape. This design increases the structural integrity of the rim and simplifies the process of setting up and maintaining a tubeless tire system.

Ceramic bearings are harder, smoother, and more durable than traditional steel bearings. They significantly reduce rolling resistance, allowing the wheel to spin more freely and efficiently, which is particularly beneficial during high-speed racing.

No, this specific model is engineered exclusively for disc brake systems. It features a disc-brake specific rim and hub design to handle the unique braking forces required for modern road bikes.

The 19 mm internal width is optimized for modern road tires, typically ranging from 25 mm to 28 mm. This width provides a stable base for the tire, improving both grip and comfort by allowing the tire to maintain a more natural shape.

This wheel is designed for a 12mm thru-axle standard, which is the current norm for modern disc-brake road bikes. It is not compatible with traditional quick-release dropouts.
