Prime CR-MO Sport Road Bike SaddleThe Prime CR-MO Sport Saddle is shaped for comfort in a relaxed, slightly more upright cycling posture. In this position, as the angle between the spine and the legs is reduced, the pelvis may tilt forward slightly into its natural comfortable position. Also, as the pelvis tilts forward, a central channel and cut-out zone in the base alleviates pressure in the soft tissue in front of the sit bones.The shallow convex profile and raised rear edge combined with an increased surface area provide a stable platform to support the sit bones. The curved wings allow clearance for the inner thigh as you pedal, and beneath the waterproof microfibre cover, a layer of high-density PU foam padding provides additional cushioning and pressure relief.The CR-MO rails also feature measurement markers. These help you adjust the fore/aft position of your saddle accurately to achieve an efficient and ergonomic pedalling motion.Features:Shallow convex profile with pressure relief channelNylon fibre base with cut-out zone for pressure reliefWaterproof microfibre coverDurable CR-MO Rails with measurement markersHigh-density PU foam paddingWeight: 252gBuy Prime Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
Prime Race Carbon Rail Road Bike SaddleThe profile of the Prime Race Saddle is carefully optimised for comfort in a tucked aerodynamic position. For riders with a flexible lower back, the pelvis remains in a more level stance in the cycling posture. The flat profile is designed to support weight through the sit bones in this position. A deep pressure relief channel with cut-out zone eliminates pressure on the softer tissue for extended comfort. The 140mm width has been tailored to accommodate the spacing of the sit bones with sufficient area to distribute pressure and offer comfort and stability. The shape quickly graduates to a narrow 40mm nose to eliminate interference with the inner thigh during the pedal stroke.Prime UD carbon fibre rails are engineered to deliver a weight saving advantage with calibrated stiffness for vibration damping. Prime’s seat rails also feature measurement markers. These help you adjust the fore/aft position of your saddle accurately to achieve an efficient and ergonomic pedalling stance.Finally, beneath the waterproof microfibre cover is a layer of high-density EVA foam padding. This works in combination with the nylon fibre base to provide a firm, minimally cushioned platform with a small degree of flex. Features:Flat profile optimised for tucked aerodynamic positioningLightweight UD carbon fibre rails with fore/aft measurement markersDeep pressure relief channel with cut-out zone for extended comfortNylon fibre base Narrow nose reduces contact with the inner thighHigh-density EVA foam paddingWeight: 200gBuy Prime Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
