The SLR Boost Endurance Superflow prioritizes comfort for long distance riding, while keeping low weight and performance at the forefront of design. The Endurance model has more padding than the SLR Boost, with Selle Italia's Light Gel Plus adding comfort to long miles. Like other saddles with the Boost designation, this short-nosed saddle helps us find a stable and comfortable position even when pushing the pace and our weight further forward on the nose. The Superflow cutout relieves perineal pressure and improves blood flow to the area, helping to reduce numbness or pain on long days in the saddle.
