Fulcrum Red Carbon XRP 6-Bolt MTB Wheelset 2014 -
Fulcrum is, and has always been, a symbol of high performance having reaction as its wheels main features.
Red Carbon is a top-of-the-range model, the lightest and best performing wheel, Fulcrum's master piece.
The new Red Carbon XRP 2011 is almost entirely made of carbon: with carbon hub and rim, and stainless steel spokes.
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 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. 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 all new carbon hub reduces weight and increases wheel reaction.
The new titanium free-wheel body increases wheel performance, and reduces weight considerably.
The stainless steel spokes are straight pull with a round variable section profile ( 2.2/2/1.6/2). The front wheel has 20 spokes (10 left cross and 10 right radial spokes) and the rear wheel has 20 (10 left cross and 10 right cross spokes).
1347g is the surprising weight of the new Red Carbon XRP 2011: 123g lighter than the already super light Red Carbon.
The new Red Carbon XRP is available in QR Standard versions, compatible with Tubeless UST tyres and with all ISO six-bolt brake systems.
Average weight*: Front: 597g, Rear: 750g The weight of the wheels does not include the quick release, and it refers to the lightest configuration.
