The already best-in-class Racing 5 wheelset goes from high to higher performance thanks to its new design. The same qualities that have made the Racing 5 such a popular wheelset in the past combine with new elements to make an affordable but race ready wheel. The new 20 spoke design in addition to the asymmetric rear rim profile offers notable performance increases in terms of both increased lateral & torsional rigidity as well as increased reactivity. The new design allows for more homogenous spoke tensions & makes for a sturdier, higher performing wheelset that weighs in at over 100 grams less than its previous version. 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 & non drive side, giving better symetry to an asymmetric component. Increased efficiency & reactivity are sure to be noted. High Grade, finest top quality Steel Bearings With Cup & Cone Construction reduce friction & ensure consistent performance over time.
