Easton EC90 Aero 55 Carbon Road Front Wheel. The Easton EC90 Aero Carbon Road Front Wheel has everything the discerning, performance minded cyclist demands: leading aerodynamics, certified road tubeless compatibility without rim strips, unrivaled braking performance, outstanding durability, and competitive weight. The Fantom rims steal the spotlight with their wide profile 19mm internal rim width, deep cross section 55mm deep, and round nose that keeps them stable in crosswinds. You will not find a faster clincher in this category and Easton's conducted the wind tunnel testing to prove it. Additionally, this the one and only carbon clincher front wheel with certified road tubeless compatibility. The EC90's hub is the superb Easton Echo while 16 radially laced Sapim CX Ray bladed spokes help this wheel slice through the air with the greatest of ease.
