Jumbo Shrimp? Oxymorons are not for morons. The Kink Big Slim Stealth Pivotal seat really is both big and slim. Built on a slim saddle body with thinfoam padding, it’s full shape most resembles the look and feel of a traditional railed seat. TheStealth system installs with a 5mm allen key and allows for a clean looking seat without the top patch. A full-bleed Kink logo brings it home.
