The Phenom Pro is a mountain bike saddle thats designed with our adaptive edge base construction allowing the outer-edge to conform to your body for a near-custom fit. Lightweight & expertly tuned for stiffness & efficiency the Phenom features a rounded anti-snag tail & the perfect amount of padding for mountain riding. On this model weve replaced the traditional pu padding in favor of an elaston foam construction thats made up of small beads that are expanded into the foam. The result? The feeling off sitting on 1000 miniature pillows rather than one piece of foam. & to keep the comfort coming we rely on our extra-wide elongated body geometry channel & short nose to provide you with proper sit bone support. Patented body geometry design is lab-tested to assure blood flow to sensitive arteries. Elaston foam provides unrivaled comfort & support on longer rides. Low-friction panels on the nose & tail improve pedaling efficiency & mobility while moving on & off the saddle. Ultra-light, strong, & oversized FACT carbon rails. Level iiPadding: medium density foam for bike feel with additional cushioning. Size / weight 207g size 155mm / weight 219g note: oversized 7x 9mm carbon rails are not compatible with seatposts equipped with side-load clamp mechanisms for 7mm round rails.
