The Selle Italia SLR Boost Saddle is one of the lightest saddles on the market for road performance. A carbon composite and nylon polymer shell pair with a Soft-Tek polyurethane cover for great comfort and low weight. It also includes titanium alloy rails which are strong, light, and affordable. The neutral shape of the saddle makes it a great choice for riders who stay still in the saddle and those who rotate as they ride. This keeps sensitive bones comfortable so you can pedal harder. The Selle Italia SLR Boost is all about road performance.
