Jalgratta tagumine ratas Fulcrum Red Zone 5 29 2WF-R AFS Boost HH12/148

The Red Zone 5 is our new wheel designed specifically for cross country and marathon use. The aim of the Fulcrum engineers has been to develop a product that is ideal for training and recreational fun, whilst being resistant and reliable for numerous uses. The new hubs share the same shell as the hubs used in the Red Zone Carbon and Red Zone 3. The differences are found in the axle and the bearings: in the Red Zone 5 we have used sealed, long-lasting and efficient bearings, which can be micro-adjusted with a specific adjustment ring. Red Zone 5 feature a 2-WAY FIT READY rim with a height of only 18.6 mm and a new asymmetrical section, which has been redesigned specifically to ensure the optimal balance of the spoke tension. The width of the rim is wider compared to previous versions, so that they can be used with lower pressures, for improved grip and control in the most extreme conditions. A tone-on tone design, with a partly glossy and partly matt finish, wraps the rim profile around the valve area, whilst the traditional red box, with the logo, can be found on the opposite side of the rim.

TECHNOLOGY

2WAY-FIT READY (MTB): We have developed our 2-Way Fit technology to ensure the perfect compatibility of our tubeless rims with normal clincher types and tubes. 2-Way Fit MTB bike wheels are perfectly multipurpose for tackling every situation. Thanks to a special impression in the valve area, the tubes are fitted with the maximum precision while keeping the tube perfectly stable inside the tyre. Housing the valve for tubeless tyres is also risk-free, with the unquestionable advantage that there are never any air infiltrations caused by non-ideal positioning when fitting.

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.

ASSYMMETRIC RIM: The asymmetry is designed to improve rim tension, balancing the forces from brakes and sprocket cassette.
