In 2025, aerodynamics are everything! Ridley’s aerodynamic engineers started from scratch to design the third generation of the Noah Fast. The result is a bike that is 100% aerodynamic. At 50 km/h, the Noah Fast is 8,5 watts faster than its predecessor. This underscores Ridley’s commitment to aerodynamics, which is part of its DNA, while continuing its rich heritagetage !

The new Noah Fast has been designed entirely in compliance with the latest UCI regulations on tube shapes and profiles.. The big news is the application of the 8:1 rule, which allows tubes eight times longer than they are wide, compared to a ratio of 3:1 previously. This has allowed for long and thin profiles on the fork and rear chainstays. The large down tube is immediately noticeable and has been specially designed to channel the airflow around the bottles without creating resistance. The head tube has been lengthened by taking advantage of the compensation triangles allowed by the UCI regulations. These surfaces located behind the head tube and around the seat tube guarantee better wind management.
In addition, a combination of symmetrical and asymmetrical profiles for the fork and rear chainstays optimizes aerodynamics. In crosswinds, the airflow follows a convex and elongated surface, thus providing more stability to the cyclist. In short, these innovations guarantee exceptional aerodynamic efficiency.
Progressive geometry
Thanks to years of sponsorship in cycling on route, Ridley observed a gradual shift in rider positions toward a more forward posture. Based on this data, engineers determined that a 76-degree seat tube angle is the median. A steeper saddle angle addresses riders' growing preference for a position with an open hip angle, improving power transfer. A lowered bottom bracket compensates for the use of wider tires in modern cycling. Finally, the lower head tube, combined with an integrated cockpit, allows the rider to adopt a more aggressive aerodynamic position, reducing frontal area.
Integrated cockpit
The Nimbus Aero cockpit has been specifically designed for this new model and has been developed in parallel with the frame. The goal was to combine aerodynamic performance with comfort. Thanks to this integration, turbulence is reduced compared to a conventional setup. The Nimbus Aero cockpit also follows the peloton's trend towards narrower handlebars (360 mm at the top). From an ergonomic point of view, flared drops ensure balanced handling, while the aerodynamic upper part of the handlebar tilts slightly towards the rider, promoting a natural wrist position resting on the top of the handlebar. The curvatures are also designed to naturally orient the shifters towards the inside. All these features comply with the strict UCI regulations regarding control placement.
Holistic approach
The new Noah Fast is not just a blazing fast bike, but a true “performance package” that takes a holistic approach to cycling. Every aspect of the bike is designed to meet the demands of modern cycling. Cockpit dimensions and geometry are tailored to professional riders’ expectations, and clearance for 34mm tires makes it confidently future-proof. Aerodynamic engineers ran all simulations with the bike as a whole, including wheels, bottles, computers, and other essentials – exactly as riders use the Noah Fast.
Official bike of the Uno-X Mobility team
From 2025, Uno-X Mobility and Ridley join forces in an intensive collaboration with a clear goal: to conquer the world of cycling. Both parties bytagshare the same values: a constant quest for innovation and improvement, driven by an unwavering passion for racing. Over the past few months, both teams have been working hard behind the scenes to optimally prepare for the new cycling season. The heirtagRidley’s wealth of experience in developing the fastest bikes, combined with the knowledge and experience of the riders, makes for a winning partnership. The Noah Fast is the result. With great ambition, Ridley and the riders look to the upcoming Classics and Grand Tours.

This is not the subject, but I would like to know if Guillaume Judas always gives advice on preparing cyclists for a cyclosportive event, I should point out right away that this is not for me, but for one of my good friends.
