Wide Rim Tech
Fulcrum®’s R&D department, following requests from the competition circuit, has worked to create rims that are wider than before, about 4 mm or more than previously. This technical choice provides an ideal basis for 25/28mm tyres, the sizes currently popular.
This ensures stability, excellent handling and superior comfort.



A more comfortable bicycle
Everyone agrees that a more comfortable bicycle means less physical and mental fatigue, generating better performance and results.
The contact made by the wider tyre creates a better, more stable support, while the shape of the tyre and rim together creates regular, stable air flow, in short, more aerodynamics, less attrition.
