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.
