Technology

2WAY-FIT READY (MTB)
2-Way Fit technology ensures that rims designed for tubeless tyres are compatible with conventional clincher tyres and inner tubes. 2-Way Fit MTB wheels are designed for use in a range of conditions. A special recess in the valve area allows the inner tube to be fitted precisely and held stably inside the tyre. A tubeless tyre valve can also be fitted securely, reducing the risk of air leakage caused by incorrect positioning.

ASYMMETRIC RIM
The asymmetric rim design helps improve spoke tension and balance the forces from the brakes and sprocket cassette.

WIDE RIM TECH
Responding to needs from the competition circuit, Fulcrum’s R&D department developed rims that are approximately 4 mm or more wider than previous versions. This technical design provides a base for 25/28 mm tyres, which are currently popular, and supports stability, handling and comfort.

AFS AXLE SYSTEM
The Axial Fixing System (AFS) is Fulcrum’s system for mounting a disc brake to the hub. Its larger mounting contact area compared with familiar standard solutions increases structural rigidity and enables more precise and powerful braking.

MICROSPLINE FREEHUB
Fulcrum applies technical developments and new technologies in its products. Following the introduction of Shimano’s 12-speed mountain-bike drivetrains, Fulcrum adopted the MICROSPLINE standard across its wheel range.

What is MICRO SPLINE?

With the arrival of 12-speed cassettes, Shimano engineers redesigned the freehub body to fit the new cassettes and their smaller 10-tooth sprocket. They also changed how the cassette mounts to the hub body. The MICRO SPLINE fitting has 23 equally spaced, angled splines for a firmer connection with the cassette. This design allows the freehub body to be made from aluminium while avoiding the deformation and gouging found on conventional aluminium cassette bodies. MICROSPLINE hubs fit current frames with Boost (148 mm) and non-Boost (142 mm) standards. MICROSPLINE hubs can only be used with MICROSPLINE-compatible cassettes.
