SA NATURAL FIT SADDLE SHEN BLACK Regular Pressure-relieving by design thanks to PONSO technology. The PONSO construction incorporates a raft of clever design elements to shift pressure off the sit bones and onto the muscles involved in pedalling and sitting. Including Y-Shade technology – a comfortable Y-shaped upper foam layer constructed from soft memory foam. It moulds to your behind for better pressure distribution and more space for the tailbone. Pressure is transferred to the muscles for noticeable relief on the sit bones. The Natural Fit ergo-relief channel reduces pressure on the perineum. Even more pressure relief comes courtesy of the special Hammock Cuts – special cutouts that cradle the sit bones so it feels like you're sitting in a hammock. This shifts pressure off the sit bones and onto the less sensitive surrounding weight-bearing muscles. Shock-absorbing rail pockets reduce vibrations travelling up from the ground. And it's all wrapped up in a durable, comfortable, high-quality PU covering. With this level of comfort, there's nothing stopping you now! pressure-relieving shell with PONSO technology; dual-foam padding with Y-Shade technology and memory foam; Natural Fit ergo-relief-channel; Hammock Cuts for extra pressure relief; steel rails; shock-absorber rail pockets; high-quality PU covering; integrated saddle adapter mount; optimised for Upright position (Saddle Finder A) size Regular (265 x 200 mm), Large (265 x 220 mm) material steel, GF-reinforced nylon PU, memory foam weight 590 g (regular) max. load capacity 100 kg
