The specific cyclocross contruction guarantees Fulcrum® quality performance despite the mud and sand frequently found in cross courses as well as a completely new and revolutionary wheel design which provides an even greater performance. The Racing 5 CX has a new 21 spoke design in addition to an asymmetric rear wheel which offer notable performance increases in reactivity as well as lateral and torsional reactivity. A new, higher performing and more resistant cyclocross wheel with a significant weight savings is perhaps the best upgrade available for your cross bike this year.
Differentiated rim height: 24 mm at the front to provide optimal handling; 27.5 mm at the rear for transmitting all your power to the wheel.
New asymmetric rim profile: asymmetrical rear rim profile allows for better balancing of spoke tensions between drive and non drive side, giving better symetry to an asymmetric component. Increased efficiency and reactivity are sure to be noted.
Double-butted steel spokes with aero profile: enable maximum aerodynamic penetration.
Two-to-One Spoke Ratio TM
Oversized hubs: increase wheel stiffness and reactivity.
Superior quality steel balls on sealed cylindrical bearings: reduce friction and ensure consistent performance over time.
Oversized flange on the drive side: provides greater torsional stiffness, increases reactivity at each change in rhythm of the pedal stroke.
Double gasket: protects the ball bearing seats from water and mud, ensures consistent performance over time.
Nominal and ETRTO width: 20,5/15
Dynamic Balance: No
Spoke anti-rotation system: No
Spoke material: Stainless Steel
Spokes: 18 radial (front) / 10 left, 10 right (rear)
