The third offspring in the successful Noah Fast family. Our engineers have pushed the frame shapes to the UCI limits: 8:1 ratio of tube shapes and compensation triangles where usefull. The Noah Fast is the result of a holistic design approach from the first frame sketch where we took into account all components like wheels, bottles, cockpit.
Every part of the frame is aerodynamically optimised to create the fastest Ridley bike ever. The down tube was systematically widened to protect the bottles from the windflow. The headtube area got more integrated into the toptube and downtube to reduce the drag. The flush cockpit is an eye catcher but more importantly it is an aero improvement!
A steep seat angle optimises the power output of the rider. With the lightest possible carbon and optimal stiffness, this bike is a pure speed machine.
