SLR Boost 3D Kit Carbonio Superflow Saddle

What Our Gearhead® Experts Are Saying:

"I’ve used the standard SLR Boost for years, but the 3D version takes it to another level. The zonal cushioning gives just enough support without feeling soft, and the carbon rails and base keep things stiff and light. It's the perfect balance for long climbs and punchy efforts. Game-changer for my road bike."

A premium build deserves a saddle that matches its performance—and the ENVE x Selle Italia SLR Boost 3D Kit Carbonio Superflow delivers just that. Developed in partnership with Selle Italia and built with cutting-edge Carbon DLS™ 3D printing, this saddle offers targeted support and zonal cushioning to keep us pushing through steep climbs, fast descents, and endless miles without hesitation.

We love how the differentiated density pattern provides progressive support exactly where we need it most, while the open Superflow cutout relieves pressure on longer efforts. Carbon rails and a carbon base reduce weight and boost stiffness for efficient power transfer, all in a compact Boost format that keeps us centered and in control. It’s more than a finishing touch—it’s a performance upgrade for riders chasing top-tier comfort and race-day readiness.
