They employ variable-section stainless steel spokes in the 2:1 Two-to-One assembly configuration on both wheels, with 16 elements on the sprocket set side of the rear wheel and on the disc side of the front, and 8 on the opposite side. The hubs fitted are of the aluminium oversize type fitted with a 20 mm axle front and rear. These wheels are compatible with Tubeless UST tyres whose availability in International Standard and AFS versions means that they can be combined with the main disc braking systems on the market.

- Red Metal 3 includes the 15mm Thru Axle Adapter Kit and the 142mm Syntace X-12 Adapter Kit (only suitable for 12mm through-bolt version).
- Average weight*: Front: 745g, Rear: 940g, 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.

2:1 Two-to-One: 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

QR - 15mm Thru-Axle Adapter System: The world of "fat wheels" is continually evolving. Mountain bikers are renowned for being keen on trying and experimenting new technical solutions adapting a bike to the route and to their riding style is normal for off road lovers. And Fulcrum does not fall behind. On the contrary, it pushes ahead and offers new solutions that don’t force you to make a definitive choice, but leave you the option to change your mind. The Fulcrum 2011 range includes the standard modification kit with quick release and 15mm thru axle for the front wheel. A clever solution that will allow you to use the Fulcrum wheels on bikes with front forks with traditional release or thru axle.

Syntace X-12 Adapter System: 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 2011 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.
