Zilco Gel-Lite pads have the impact and pressure absorption properties of traditional gel pads, but are up to 80% lighter. They can be used under all types of saddles – including race & exercise saddles, and are machine washable. The Rear Lift pad has one layer of Gel-Lite throughout, with a removable insert that provides double thickness at the back. It is designed to correct the balance of saddles that tip back. Weighs approximately 640g. Can also be used without the inserts as a normal riser pad.
