Saddles

Right from the outset, we wanted to push the boundaries of saddle design to deliver a beautiful cutting-edge product that performs at the highest level. Working closely with engineers from Airbus Group Innovation and utilising Additive Layer Manufacturing technology enabled us to create a saddle design previously considered unachievable using carbon material. The result is an ultra-lightweight saddle with a distinctly unique, organic form. Flexible carbon base and ‘leaf spring’ carbon rails -The carbon rails of the ALM saddle are laid in a unique way that allows them to work as a leaf spring, making them incredibly strong yet with in-built flexibility for rider comfort. Designed in partnership with Airbus -Fabric searches for technologies & materials from other industries that can benefit cyclists. A collaboration with Airbus Group Innovations introduced aerospace technology to cycling, resulting in the development of the ALM saddle. Feather weight comfort at 140g -As you’d expect from an all carbon saddle, the ALM is extremely lightweight. Comfort is achieved through the flexible rails & padded topper. A truly revolutionary saddle that delivers both performance and comfort. -Width: 142mm -Length: 282mm -Rails: Leaf spring carbon fibre -Base: Aerospace UD carbon fibre -Pad: Ultra-light PU foam -Cover: Vacuum bonded -Weight limit: 100kg
