Is it possible to increase the aerodynamic penetration of the racing bike? Without a doubt. Our wheels of Serie Srl guarantee better aerodynamics thanks to a wider channel (21mm for the SLR42 and 19mm for the SLR38) and the profiles optimized by 38 and 42mm. The thickness of the carbon profile is different depending on the circle area, suitably increased L where the radius and the nipple are inserted. The variable lamination process allows you to reach a total weight per pair of wheels of 1587 grams for SLR42 and 1531 grams for the SLR38. Both versions are Tubeless Ready.
