The aluminum rims have a differentiated profile front and rear. The front wheel height is 26mm to achieve perfect aerodynamic penetration, while the rear increases to 30mm to provide all the stiffness necessary to transmit every watt of your power. Both rims feature the characteristic Fulcrum® toroidal milling between the anchoring points of the spokes. The fact that the rim grooves do not have holes translates into greater torsional stiffness and greater vertical elasticity.
The spokes are in aluminum with aero profile and a central section of 2.6mm, 16 radial for the front wheel and 21 for the rear wheel distributed according to the famous Fulcrum® 2:1 spoking, with double the number of spokes on the cassette side. The nipples are in aluminum, too, which reduces the important peripheral mass of the wheel, thereby increasing its performance in acceleration.
The oversize hubs are in aluminum. Smoothness is guaranteed by special bearings designed and produced by Fulcrum® that have many more balls than normal industrial bearings and hence produce unparalleled smoothness.
Racing 1 wheels were born to be fast, so Fulcrum has equipped them with the patented Dynamic BalanceTM system that makes them stable and precise even at high speed.
