A carbon front hub with oversize flange is used creating a light weight but stiff hub. The rear hub is single piece aluminium for increased stiffness. Differentiated rim heights – 25mm at front for optimal manoeuvrability; 30mm at rear for optimal power transfer, with 22.5mm rim width for improves stiffness and rolling resistance.
The rims are also triple milled to reduce rotational weight and create an aerodynamic profile. Fulcrum Dynamic Balance keeps the Racing zero wheels perfectly stable but is achieved in the rim milling process rather than spokes in the Racing 5.
The 2:1 spoke ratio on rear wheel double the number of spokes on the drive side for greater wheel stability and improved power transfer in the rear wheel. these wheels have 16 radial aero spokes on front wheel and 21 on the rear.
The Racing Zero wheels feature Fulcrums USB ceramic bearings which are 30% lighter 40% more resistant and 50% smoother compared to the steel bearings featured in the 3's 5's and 7's.
