Whether you race in the pro peloton, hammer with a local club team or just compete against yourself, the classic curves and futuristic inForm BioDynamics technology of the new Serano RXL saddle offers the optimal combination of fit and efficiency for the aggressive road riding. With a turned up tail, the Serano RXL promotes a low, forward position on the bike, with a power pocket for huge wattage. Oversized carbon rails and a carbon-composite shell keep it ultralight and supportive.
