About Fulcrum Racing Speed XLR 35 Tubular Wheelset - Dark
The new Racing Speed XLR 35 completes the Fulcrum range of high performance road racing wheels. It is perhaps the most versatile wheel in the line-up and offers serious performance advantages in almost every situation. Light enough to climb the steepest gradients, reactive enough to please the strongest sprinter and aerodynamic enough to save precious energy this wheel is the perfect do-it all performance wheel. Working diligently to develop new carbon layup specifically for this profile the engineers were able to produce a lower profile and extremely lightweight rim, whose stiffness rivals that of its higher profile counterparts. Add in the revolutionary new 3Diamant surface treatment that ensures exceptional braking performance in both wet and dry conditions and you have a wheelset that is ready for the podium.
F.I.C. Fulcrum Identification Card
Fulcrum supplies each wheel with its own Identity Card (ID) which uniquely identifies the wheel and certifies that it has been manually assembled and has passed all tests required by the strict quality protocol. The F.I.C. ensures that you have bought a genuine Fulcrum product.
The Racing Speed XLR 35 wheelset is entirely hand-assembled by a specialised Fulcrum technician and is checked in every tiny detail with electronic instrumentation. This ensures maximum performance and reliability for all Fulcrum wheels.
- 3DIAMANT BRAKE SURFACE TREATMENT
- using advanced machinery and state of the art diamond tipped precision tools, eliminates imperfections. This new process eliminates the “breaking-in” period, improves braking performance under both wet and dry conditions and creates a more linear and smooth overall braking performance.
- CULT - Ceramic Ultimate Level Technology
- Top quality ceramic balls, thanks to the absence of lubricating grease and the precision machining of the cup/cone, allow to drastically reduce the friction coefficient and thus increase the smoothness of the wheel by as much as 9 times compared to standard bearings.
- DYNAMIC BALANCE
- The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the section of the rim opposite the rim joint.
- SPOKES ANTI-ROTATION SYSTEM
- keeps the spokes consistently in the position of maximum aerodynamic penetration.
- 2:1 SPOKE RATIO
- the number of spokes on the rear drive side is double that of the opposite side. Greater stability of the wheel thanks to the perfect balance between the spoke tensions – greater torsional stiffness and greater reactivity.
- CUP AND CONE BEARINGS
- easy ball/bearing adjustment – reduces possible ball/bearing play – precision operation – maintains performance over time.
