Serfas gel bike seat

Serfas RX Saddle - Protecting Your Junk Since 1998 Serfas' RX saddles have a full length anatomical groove down the middle of the saddle along with an elevated seat position. This has proven to eliminate pressure & significantly reduce numbness around your soft tissue (plumbing) & put weight where it belongs—around your sit bones. This means you can spend more time in the saddle without sacrificing comfort.
