Red Zone™ has been created for riders who love using their mountain bike with no limits. We could define it as Enduro-Freeride, or if you prefer, a wheel that’s light and reactive for climbs and strong and resistant when you decide to lift the wheels off the ground.
The rims are class 21 lightened between one spoke and the other, so we have a rim that is strong but at the same light. Both the front and rear wheels have 24 stainless steel spokes with variable thickness 2.2/1.8/2, with reinforced head, distributed according to Fulcrum® 2:1 technology with double the number of spokes on the cassette side for the rear wheel and disc side for the front. This means getting the maximum performance both when pedalling and manoeuvring.
Red Zone™ is compatible with UST tubeless tyres and with all ISO six-bolt braking systems.
Ultrafit 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-OneTM 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™ 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.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 AFSTM 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.
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 Red Metal 1XL, Red Metal 3 wheels, along with the basic and XLR version of the Red Zone wheels, 100% compatible with the German company’s new standard. It is extremely easy to assemble, with no need for any special tools.

not for rider >75kg, not for enduro, just light AM
Is impossible to service the wheel! One time that the rim is compromised you have to drop the entire wheel.
Use only large >2.3 tyres, rubber is the only thing that can save the not replaceable rim!

This wheel seemed to tick a lot of boxes for me, but the unusual spoke layout is not worth it.
The 24h rim, and 2:1 spokes means that the spokes on the non drive side have to be much higher tension than their opposites.
The wheels are difficult to true, replacement spokes are hugely expensive, and replacement rims are not available.

Rated 1 out of 5 by Anonymous Nice wheels until I broke a spoke. I've been trying to get a replacement for weeks now, but it seems no shop has a stock of replacement spokes, probably also because you can only buy them in a set of 8 and as there are two different sizes, you need to get 16 spokes for about 150 € to be on a safe side. I also tried at bike festival on Lago di Garda, where Fulcrum had its place and a mechanic, but they where without any spare parts - how is that for a service, how stupid is to offer no support for a new product (from 2010) on the market ;-(
