About Dean Fast

The Dean Fast is one of the absolute fastest time trial bikes in the world. It incorporates every Ridley aero technology to create a truly unique bike.

The Dean Fast's frontal drag is incredibly minimal thanks to meticulous attention paid by our engineers. Its aerodynamic head tube and fully integrated Forza time trial handlebar helps keep airflow clean. Transition from handlebar to frame is incredibly smooth, while wheels are perfectly integrated into the frame.

The Dean Fast comes with several dropouts to ensure that your specific rear wheels fit perfectly with the frame every time.

The Forza handlebar is a blessing for bike fitters. The armrests and extensions work completely independently of each other to set the perfect seating position.


Shimano Dura-Ace Di2

The Dura-Ace Di2 is the cream of the crop. Built as light as possible to enable the switching of gears as precisely as possible, to ride as fast as possible; that is how you can summarise the Dura-Ace Di2. This group even makes pros jealous.

About the Dean family

Our Dean time trial bikes are the ultimate speed machines that let you race off the starting ramp or fly out of the transition area. Every detail of a Dean is designed to cut through the wind as smoothly as possible. It is easily considered one of the top time trial bikes as it causes little resistance while flying from point A to B, perfectly converting every watt into pure speed.

Despite the obsessive focus on performance, strong attention is also paid to optimal comfort. We all know that a time trial is a war of attrition which translates into "the higher the comfort, the longer the distance that can be travelled at high speed." Basically, the Dean ensures that you get the most out of your body, at every moment of the ride!
