. The Scratch II PAS CPC Nack Saddle from Prologo utilises its round shape design to provide fantastic support & comfort for long/medium distance road & off-road riding. This unisex seat distributes the weight on the whole seating area, which lowers the intensity of the pressure put on your pelvic area thanks to its PAS technology system, allowing your pelvis to rotate as naturally as possible as you pedal. Equipped with a full-carbon Nack rail system, it keeps a light weight, adding further to an ergonomic & comfortable saddle.

Features: Rail:  Nack Cover:  Microfiber + CPC Padding:  Light Foam Length: 280mm
Width: 134mm Weight: 185g Technology. Nack:   The Nack rail is constructed from a nano carbon fibre. It consists of a blend of carbon, kevlar & aluminium filaments that integrated at the seat-post clamp area. They are arranged in a production process called Braided Carbon Rail (BCR) to give exceptional strength. Nack rails give the optimal weight & durability required of a performance saddle that is intended for mountain bike riding. Connect Power Control:  CPC is Prologo’s patented name for these new saddles featuring dense bunches of short, suction cup like gel polymer tubes. This technology has been used in Moto GP & Formula 1, largely in gloves for the racers, but Prologo are the only ones to use it in cycling. Grip is also vastly enhanced as the hollow CPC Volcano heads enlarge the surface area of the saddle, while the CPC heads in all the optimal contact areas reduce slip improving power output & control. The elastic polymer CPC heads absorb shock by expanding at their bases on impact & the ergonomic, lightweight design allows air movement & cooling. Pas System (perineal area system):  This system is designed to eliminate pressure spikes & numbness in the pelvic area. The Pas System is achieved thanks to an advanced memory foam style padding which shapes to the rider's sit bone shape. This ensures that pelvis movement during very long distance cycles is not strenuous. The final result is comfort & performance with no feeling of fatigue or numbness. ESD Ergo Shape Design (ESD):  The ergonomic design gives the saddle a very slender front section, which quickly opens out to the full width of the saddle. ESD permits a round stroke, allowing the rider to maintain a natural position when relaxing or in the attack position. The forward saddle profile gives the thighs more room during all phases of the pedal stroke, whereas the rear part of the saddle helps the rider to find the correct support for the Ischial bones. It also helps to avoid riders tendency to slide forward & instead favours the natural rotation of the pelvis Buy  Pro Logo Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Its active foam is separated to create five comfort zones working in a smart & individual way that favours the natural movement of the pedalling phases both of pushing & pulling. This also allows it to absorb the vibrations that the carbon fibre base transfers to the saddle. The round shape of the M5 provides natural pelvis rotation, creating stability & support for your lumbar areas, & the distribution of the pressures on a greater surface.CPC Technology Benefitting from Connect Power Control (CPC) technology that's the same as used in Formula 1 racing, PROLOGO has patented it specifically for the cycling industry. This saddle uses 3D polymer cones to maximise grip when taking up an aggressive position as well as making it possible change position quickly. Offering high levels of vibration absorbing, grip & position stability, its CPC technology also reduces muscle fatigue & facilitates air flow by reducing the temperature in the contact zone. Despite the absence of a real perineal channel, the SCRATCH M5 has an open base able to eliminate pressure peaks in the genital pelvic area. The closure of the prostate zone also offers better protection against extreme climatic conditions (rain or mud).
