When race season is around the corner, you'll want every advantage you can get. This includes under your sit bones, and Selle Italia's SLR Kit Carbonio Boost Superflow Saddle is tuned to provide every edge you could need when you're toeing the line. The SLR Kit Carbonio is one of the many welcome results from Selle Italia's extensive research into the most effective saddle designs. They introduce a unique rear frame that innovates on traditional ideas to allow independent flex of the left and right side of the saddle, so you can ride with more effective support on the alernating motions of your hips while you pedal, resulting in improved overall comfort, without faltering on stability when you're hammering on the pedals going for the breakaway. This technology is then paired up with a large center cutout that relieves perineal pressure, aiming to reduce numbness and pain that can be associated with long hours in the saddle. Selle Italia crafts most of their saddles within a scale in its lineup, and the SLR Kit Carbonio Boost Superflow lands near the top, just a notch behind the featherweight Tekno verson, scaling in at just 12-grams heavier -- hardly a noticeable difference. It features a more compact shape than the standard SLR, with a shorter nose that stands out against the competition, and a construction that's optimized for racing. By using CarboKeramic rails and a shell comprised of a carbon fiber/nylon blend, Selle Italia is still able to achieve an impressive weight, but without any durability concerns or a rider weight limit.
