Fulcrum Racing 1 Clincher Wheelset 2012. Racing 1 wheels have competition in their DNA. If you’re looking for a lightweight wheel that gives the best performance under any condition and has a marvellously aggressive look, you’ve found it. The aluminium 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. So buy this Fulcrum Racing 1 Clincher Wheelset Now £487.49.
