When you need toughness guaranteed but don't want to add an anchor to your rig, Fizik's Gobi M5 Mg saddle provides just what you're looking for. The carbon reinforced Nylon TwinFlex shell moves with the rider's pedal stroke, offering unmatched comfort and an exceptional fit. Rugged manganese rails keep the overall weight down while providing toughness you'll notice after miles and miles. As always, it boasts the features and quality you expect from a Fizik: a Microtex cover with efficiency-enhancing Cordura thigh glides, and supportive, comfortable padding for on-the-trail comfort.
