SPHERIK 6S8 is one of the best aero carbon clincher road bike wheelsets. The ultimate choice for riders who are concerned by aerodynamics and do not want to compromise with the weight. The 6S8 wheelset is an asymmetrical 60mm deep front rim and 85mm deep rear rim. Combining aerodynamics, stability and lightweight, the 6S8 is the best choice for those of us who want the perfect wheel set for time trials or triathlons. Extremely stable in crosswinds because of the lower profile rim on the front, stiff but very comfortable because of the higher profile rim at the back, the 6S8 is the best wheelset for riders who race against the clock. Built around the SPHERIK 100% carbon clincher rim (Toray T700 3K with Unidirectional fiber as final layer) the 6S8 is designed for pure speed on both flat terrain and rolling hills. SPHERIK comp road hubs use superior quality steel bearings to eliminate internal friction and thereby increase riding efficiency and durability. You can be confident when applying the brakes on the high-temperature TG resin Carbon/Ceramic breaking surface. The patented TG resin carbon/ceramic process allows you to stop quicker and with greater stability. Because the rim can endure the ultra high breaking heat of 240 Celsius, you can achieve more durability and more breaking efficiency on long descents.
