The Enduro lays down some clear rules: the cyclist must be able to rely on solid and agile materials that are suitable for climbing and especially descending, when speed reaches its max and the terrain is varied, often very technical and sometimes with a number of crucial points that are unknown. 

This is an extremely selective discipline in which every single mechanical component is pushed to the limit for prolonged periods of time.

Because of the tough conditions the wheels are required to perform in, Fulcrum's R&D department has chosen to create a Trail-Enduro wheel that's shorter and wider: the result is a stable, secure and fast support base.

The rim has a 27C groove and uses its wide base to keep the tyre in shape even in the nastiest of bends, while the structure of the wheel offers optimum support thanks to its 28 straight head spokes that make the wheel more solid and reactive.

There's no room for hesitation here, it's all about choosing the right line, placing your trust in the material and you're off.


AFS Axle System - The Axial Fixing System is the solution developed by Fulcrum® to fix the disc brake to the hub. The constraint granted by the butt area of the release mechanism, greater than in familiar standard ones, makes it possible to obtain greater structural rigidity and therefore more precise and powerful braking.

One Hub Fits All

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.

2Way - Fit Ready (MTB) - This procedure transforms Red Zone 500-700 and Red Fire 500 wheels (designed to be used with an inner tube) into Tubeless Ready wheels (i.e. without the use of an inner tube but with the compulsory use of a sealant liquid).

Micrspline Freehub - They understand technical evolution as painstaking attention to product development, and it’s one of the cornerstones of all projects that come out of our R&D Department.

The Fulcrum spirit entails a constant effort to pick up and seize on new trends and keep pace with the most advanced technologies available.

This is why we adopted Shimano's Microspline standard as soon as the new racing drivetrains for 12-speed mountain bikes were presented, and will introduce the ground-breaking technology throughout our range.

The Shimano Microspline option will be available on all MTB and E-MTB wheels in the MY2020 catalogue.

At the same time, it will be possible to convert all wheels in the Red Zone, Red Metal and Red Fire range and all previously purchased and used E-MTBs featuring different bodies using a conversion kit comprising body and pivot.
