The evolution of a successful model, this road bike saddle features a completely revised design that's engineered for the demands of modern road cycling. It comes equipped with a high-quality microfeel cover, which uses its microfibre material to offer greater resistance against abrasion and weather while remaining durable and easy to clean. Selle San Marco has also kitted out this version with a carbon-reinforced nylon shell, which has a high-performance nylon construction that's enhanced with carbon fibres that are built with variable thicknesses and reinforced by ribs and bridges. This allows it to deliver greater rigidity, ergonomics and durability characteristics, without affecting weight to the shell. The Shortfit model is the most aggressive saddle in the collection. It is distinguished by its short length and maximised central cut-out. The excellent, generous rear support makes this model ideal for those athletes who rotate their pelvis a lot whilst pedalling and as a result, move closer towards the handlebars. Its technical structure makes it particularly suitable for road use. Selle San Marco presents Shortfit 2.0: the updated model marks a new chapter of one of the most successful products of the historical Italian company. Adapted to the most advanced technologies, the Shortfit 2.0 comes to the market with renewed features, but always remains faithful to the tradition of craftsmanship that has always distinguished the brand.
