The Selle Italia SLR Boost TM Superflow saddle will support the fanatic rider in a very effective fashion. The specific shape makes it easier to stay in the saddle and reduces the chance of sliding. The weight is also relatively low, as this saddle is one of the lightest in its price range! Saddle shape This saddle has a semi-round rear part, making it highly suitable for riders who move a little while they ride and whose hips rock a little from side to side. The semi-round shape provides plenty of support for those riders while maintaining sufficient freedom of movement compared to a flat saddle. Flexibility This is an S-shaped saddle, meaning it’s raised at the back and lowered in the middle. This S-shape makes it possible for people with an inflexible spine to assume a proper riding position. This has to do with how easy these riders find it to rotate their pelvis. People with an inflexible spine often have more trouble rotating their pelvis, meaning they could use some extra support. Cut-out This saddle has a cut-out and alleviates pressure for those who often experience discomfort or pressure to their soft tissue areas.
