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 RatioTM
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.
