Keep it low and aero without sacrificing comfort. The Cr-Mo railed, lightweight Romin EVO Comp Gel is a road saddle contoured to put you in a position for optimal power transfer and comfort as you put pressure on your competition.

Patented Body Geometry design is lab-tested to assure blood flow to sensitive arteries. Stiff, carbon-reinforced shell for longevity and all-day riding efficiency. Lightweight and supportive PU foam with gel inserts for increased comfort on long rides. Durable hollow Cr-Mo rails. Tough, lightweight, and water-resistant Micromatrix(TM) cover.
