SLR Boost 3D Superflow Carbon Saddle

What Our Gearhead® Experts Are Saying:

"I didn’t expect a race-weight saddle to feel this plush, but the 3D print really delivers. I can move on the bike without pressure points, and the extended rails give me way more setup range."

Futuristic comfort meets legendary road pedigree in the SLR Boost 3D Kit Carbonio Superflow. Designed with Selle Italia’s most advanced materials, this high-performance saddle features a fully 3D-printed surface that delivers progressive support through differentiated cushioning zones—dense under the sit bones for power transfer, softer near the center for pressure relief.

A Superflow cut-out channels pressure away from sensitive areas, helping you stay focused and strong over long distances. Meanwhile, the +10mm rail extension opens up a wider range of fit options, making this saddle highly compatible with aggressive frame geometries and rider setups.

Its neutral shape suits both dynamic and static postures, offering ergonomic performance for a broad range of riding styles. And thanks to its compact footprint, short-nose design, and lightweight carbon rails, this saddle is ready for race day, training blocks, and everything in between.
