Partnering ENVE, the innovative engineers known for light, strong components, with Selle Italia, an Italian brand with a 120-year history of saddle creation, the ENVE x Selle Italia Boost SLR Saddle will ensure your all-day racing comfort.

Available in a choice of widths, with either carbon or titanium rails, this short-nosed saddle bears a cut-out that helps to keep its weight down and flexes the lumbar spine, while the wide SLR shape, conceived with the help of doctors and biomechanics scientists, helps position the pelvis so that the force goes through your strong sit bones, not your delicate soft tissues, as you ride.

The saddle is furthermore perforated, to keep you dry and fresh over long miles on the bike, and coated in a soft, polyurethane upper to add a bit of luxury to your ride experience.

The carbon rails are lighter than the titanium, but also stiffer and more aggressive, making them capable of absorbing more road vibrations. They’re also oblong rather than round, so you’ll need to check the fit with your saddle post. The round, hollow titanium rails will be compatible with a greater range of bikes and offer a softer ride but won’t absorb vibrations as well as the carbon.  

Whichever width or rail you go with, rest assured that your saddle will be super light and has been designed to let you adopt an aggressive race stance for longer, while staying comfortable and avoiding strains.
