Features The Red Metal 5 are the entry-level wheels in the Fulcrum off-road range. They are designed to improve the performance of your bicycle thanks to the Fulcrum innovations: Two-to-One spoke ratio, disc brakes, and 20mm oversize axles. Red Metal 5 wheels allow all enthusiasts to enter the Fulcrum® Off-Road universe.

Their rim has a specific profile for disc brakes with a height of 19 mm, a bonded joint and black anodized finish. This is the same finish that distinguishes the spokes mounted in a 2:1 Two-to-One™ configuration with 16 elements on the sprocket set and disc side and eight elements on the other. The axles, with a 20 mm diameter both front and rear, run on sealed bearings. The freewheel, with a steel body, turns on sealed bearings.

The total weight is 1805g, compatibility is guaranteed with standard tires with rim tape, and the disc assembly option is envisaged in the International Standard and with AFS™, and therefore with the most common braking system.

The weight of the wheels does not include the quick release, and it refers to the lightest configuration. Average weight: front: 821g, rear: 984g

Features:

• 2:1 Two-to-One™ Spoke Ratio: The 2:1 Two-to-One™ system has been used for all the rear wheels and for the first time Fulcrum® has also extended their advantages to all the front wheels fitted with disc brakes. The doubling of the spokes on the critical side makes it possible to reduce the unit load borne by each spoke as the spokes themselves are no longer subject to the mechanical stress resulting from the different disc. Overcoming this drawback the spokes will be able to transfer the forces exerted at the rear by the pedalling traction and at the front by the torsion torque of braking, and give the front wheel previously unknown stability.

• Quick-releases for Off-Road wheels: The quick-releases make use of the new patented Fulcrum® mechanism: a locking lever centered on the axis of the axle. This lever engages both ends of the axle fitted with a cam that exerts the closing traction on the axis, by means of a fork coupling. The synchrony with which the lever fork exerts the torsion on the ends of the eccentric axle makes the operation for locking and releasing the component more fluid, smooth and secure.

• Axial Fixing 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. The availability of the International Standard option ensures full compatibility of Fulcrum® wheels even with the most widespread braking systems that use this assembly plan.

• Oversize Axle: The hubs designed for Fulcrum® wheels employ a generously dimensioned design for both the central body and for the rotation axis. The diameter of the latter, 20 mm for all the models with disc brakes, guarantees high resistance to transverse and torsional stresses. A contribution is also made to this result by the mechanical architecture of the hub which, in the AFS™ version, is provided with bearings with a double ball-bearing race positioned outside the flange, so that it is aligned with the disc on the respective side. The Red Metal™ Zero and Red Metal™ 1 models are fitted with precision bearings with cones and cups which make fine adjustment possible and with a double gasket to provide a barrier against the infiltration of dust and mud.
