Selle San Marco Shortfit 2.0 Carbon FX Saddle - Black-Black - Wide (L3)}, Black-Black
  • £179.99

Selle San Marco Shortfit 2.0 Carbon FX SaddleComing equipped with a hard-wearing microfeel cover, this road bike saddle is designed to keep you supported wherever your journey takes you. Its generous rear support also makes this model ideal for athletes who rotate their pelvis a lot whilst pedalling and as a result, move closer towards the handlebars. Selle San Marco has also kitted out this version with a glass fibre reinforced shell for an excellent balance of stiffness and strength, while its technical structure makes it particularly suitable for road use.Biofoam Padding and Central Cut OutThe Shortfit model is the most aggressive saddle in the collection. It features Biofoam padding, which makes it tailored for riders who want to go the extra distance with extra comfort. Its biodynamic structure follows the movements of your pelvis during pedalling to guarantee comfort, reduce weight and deliver ideal support. The “closed cells” surface assures the water repellency of the padding. Distinguished by its short length and maximised central cut-out, this model also removes pressure from around your sit bones to reduce the chances of numbness or fatigue during long days out on the road.Road Saddle with Carbon Fibre RailsEngineered for performance, ergonomics and style, this saddle boasts a glass fibre reinforced shell that uses techno-polymer to allow it to cope with static and dynamic loads and ageing. Its special polymer construction has high physical and mechanical characteristics to increase its rigidity, toughness and ductility on every mile of road.Features: Cover Material: Microfeel Shell Material: Glass Fibre Reinforced Rails Material: Carbon Fibre Padding: Biofoam Use: Road Size: Narrow S3 Option: 140x255mm; Wide L3 Option: 155x255mm Rails Size: 9.8x7mm Weight: Narrow S3 Option: 185g; Wide L3 Option: 190gManufacturer's Part Numbers: SMS287WN401 Black Narrow (S3) SMS287WW401 Black Wide (L3)Buy Selle San Marco Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
