About Dean Fast Disc

We embarked on the development of ournew time trial bike, the Dean Fast, with the ambitious goal of setting a new benchmark for aero TT bikes. Our objective was clear: reduce drag and increase speed, pushing the boundaries of what is permissible under UCI regulations. 

To achieve this, we turned to Computational Fluid Dynamics (CFD). Using CFD simulations, we were able to identify new designs that would minimize drag at speeds around 55 km/h. Afterward the results were validated in the windtunnel at Bike Valley.

The Dean Fast pushes the limits of the latest UCI regulations including the 8:1 rule for tube dimensions and the use of compensation triangles. The F-Surface Plus on the frame and vork create a controlled amount of turbulence, allowing the main airflow to closely follow the tube’s shape.

A removable front derailleur hanger means that riders choosing a 1x set-up, will get the sleekest look possible when using the bespoke cover that replaces the hanger. 

Other features to keep in mind are the maximum tire clearance of 32mm, the UDH hanger and the fact that the frame is developped only for electronic groupsets.

The ultimate test for the Dean Fast was the U23 World Championship Time Trial in 2022 where Alec Segaert won the silver medal racing the the final prototype.

F-Tubing & F-Surface Plus

How can you ride faster without pedaling harder? How do objects "cut" through wind? While researching ways to improve aerodynamics, the bicycle industry began to gather knowledge from the aviation industry. From this, well-known NACA flight profiles, for designing wings and other components, began to be applied to the tubes of a bike frame.

With further research, our engineers found many additional potential optimisations. By shortening the end of the NACA profiles (F-Tubing), we discovered that drag was reduced. We also created a groove in the frame called the F-Surface Plus. By applying this technique, we created an airflow that flows more efficiently along the tube.

UDH Hanger

The universal derailleur hanger (UDH) is the new standard in the cycling world. Not only is this derailleur hanger compatible with all modern shifting groups, it also protects against derailleur breakage and chain drops. In mountain biking, UDH has long been very common, and Ridley is bringing the technology to other segments as well.

Ridley Elite Carbon

Our carbon is manufactured by world market leader: Toray. The Japanese manufacturer is leader in every aspect of carbon development and supplier to absolute top world brands in many industries. For the Elite Series, we use every type of available carbon: 60T, 50T, 30T and 24T.

The higher the 'Ton', the higher the tensile strength of the carbon fibers and the more intensive the development and processing. With 60T, you may need fewer layers of carbon to achieve the desired stiffness as well as the lightest possible bike, but if you built the whole frame with 60T you'd have a very uncomfortable, over-responsive ride. Hence, a mix of 24T, 30T, 50T and 60T carbon is essential as each carbon serves a certain purpose in perfectly balancing stiffness, weight and comfort.

Each bike's unique carbon mix is dependent on its purpose, such as climbing, endurance, etc. In addition, each area of each frame requires its own unique mix depending on its function such as to provide comfort or stiffness. It is here, in the unique carbon compositions, where Ridley makes the difference!

As all our professional teams ride our Ridley Elite Series bikes - including the likes of Tim Wellens, Caleb Ewan or Thomas De Gendt, this means that your bike is treated with the exact same care as theirs.
