It’s an absolutely multipurpose model that could be defined as Enduro-Freeride. • The aluminium rims are specially milled for lightening between the anchoring points of the spokes to obtain a rim that’s extremely resistant to impact yet also very light. • The aluminium spokes are designed and produced by Fulcrum® to ensure the maximum performance in every moment and in every situation. • Both the front and rear wheels have 24 spokes, distributed according to the exclusive Fulcrum® 2:1 spoke ratio, which significantly increases your power transmission and your manoeuvring precision. • Red Zone™ XLR wheels are compatible with tubeless tires, which adhere perfectly thanks to the Ultra-Fit™ Tubeless system, eliminating energy dispersion to the advantage of speed and therefore of overall performance. • Red Zone™ XLR is compatible with all ISO six-bolt braking systems. • Average weight*: Front 15 thru-axle: 770g, Rear: 950g, front 20 thru-axle: 785 g rear 12 thru-axle: 935g, The weight of the wheels does not include the quick release, and it refers to the lightest configuration.
Technologies: • Ultra-Fit™ Tubeless: Imagine the rim and tyre as a single unit composed of two materials. This is what we wanted to achieve conceptually with Ultra-Fit™ Tubeless technology. The rim was developed during the design stage to obtain perfect adherence with the tyre. The consequent elimination of friction makes it possible to improve performance considerably. Energy dispersion is drastically reduced by the tubeless tyre. The advantages are indisputable even in terms of practicality. Fitting the tyre is facilitated by the form of the rim while two tracks in the rim groove help keep the type perfectly positioned at all times. Ultra-Fit™ Tubeless technology is used in Red Carbon™ and Red Fire™ wheels. • The 2:1 Two-to-One™system: 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. • MoMag™: MoMag™ technology is integrated in wheels which do not have drilling of the top bridge of the rim. The nipples in these wheels are guided to their seat by employing a little magnet. Their accessibility from the outside makes it possible to carry out all the spoke tensioning and replacement operations conveniently. The absence of holes on the rim permits all the original strength to be maintained as well as the use of tubeless tyres. The hermetically sealed valve ensures that the tubeless tyre is kept under pressure. • 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. • Syntace x-12: The Syntace X-12 standard, with a 142mm rear O.L.D. and an innovative way of adjusting the wheel to the stay, is the new feature on many branded frames. Fulcrum, which has always kept a close eye on the needs and demands of the market, has found a solution for this: for its range Fulcrum’s R&D department has designed and developed a special kit that changes 12/135mm thru axle wheels into 12/142mm thru axle wheels thanks to a simple kit included with the wheels. This solution will make your wheels, 100% compatible with the German company’s new standard. It is extremely easy to assemble, with no need for any special tools.
Rated 5 out of 5 by BCIYA Excellent wheels
I've been running these on my AM bike for about 3 years... these are the first wheels that I haven't trashed! Very strong and roll fast! Running tubeless is super easy with these rims too. Buy with confidence.
