| Merchant: Nashbar Mercury Wheels S9C Carbon Road Wheelset. When it comes to aerodynamic, high-performance road wheels the Mercury Wheels S9C carbon wheelset is in a class of its own. Their carbon fiber rims are plenty deep at 80mm, plenty wide at 23.5mm, and have been race-proven by the SmartStop professional cycling team. The S9C wheels are the perfect choice for any event on flat roads where aerodynamics play the most important role. Whether it is a time trial, triathlon, long road race, criterium, or simply your weekly group ride, the S9Cs help serve up blazing speed. And don't fret about crosswinds the rims have a rounded trailing edge to help you stay stable during any crosswind situation. Additionally, the S9C's rims are a solid 23.5mm wide, which means you can run lower PSI for a more comfortable ride that corners with unparalleled confidence. Wider rims also have some counter-intuitive effects when compared to those standard 19mm rims: they actually decrease rolling resistance and increase aerodynamics.
