SLR Kit Carbonio Boost Superflow Carbon Saddle

What Our Gearhead® Experts Are Saying:

"This is the saddle I trust for stage races and big training blocks. It’s incredibly light but doesn’t skimp on comfort. I get great support, zero pressure thanks to the cut-out, and the extra rail length helps me dial in fit perfectly on all my bikes."

Engineered for long-distance road performance and tailored fit, the SLR Boost Kit Carbonio Superflow brings race-focused design together with ergonomic comfort. Selle Italia’s neutral shape and Superflow cut-out combine to support the ischial bones while reducing pressure through the center channel—so we can stay fully focused, not fidgeting, as the miles stack up.

Its compact profile and shorter nose make it easy to stay centered and efficient while climbing or shifting forward on sprints. And thanks to extended carbon rails, we’ve got extra room to fine-tune saddle position across all bike geometries. Whether we're climbing alpine passes or crushing tempo rides, this saddle has become a core part of our fit and performance.
