With the SLR Boost TM Superflow saddle, Selle Italia have redesigned their classic SLR. The Boost model is also designed for performance, comfort and lightness, yet comes in a much more compact design. Compared to the classic SLR, the SLR Boost is 25 mm shorter and comes with a different nose design, which helps save weight and offers additional comfort when pushing the pedals. In combination with an open Superflow relief channel, the short fit model helps you easily find and maintain an ideal riding posture, even on long, varied and strength-sapping rides.Details:a Light, comfortable race saddle with a compact designa Intended use: Road, Gravela Central Superflow cutout (relieves the perineal area)a Light, flexible manganese steel alloy railsa Lateral Frame Visibility (less stress on the cover)a Slightly raised rear parta Perfect for riders with strong pelvic rotationSpecs:a Cover: polyurethane (Soft-Tek)a Rails: chrome-manganese alloy ; 7 mm
