Ridley's new time trial bike was spotted at the Criterium du Dauphiné, where the 31km stage 4 time trial started in Cours and finished in Belmont de la Loire. At least two Lotto-Destney riders, Victor Campenaerts and Thomas De Gendt, were on new machines.

This week's mega-gallery featured a variety of Dauphine tech, including three other prototype roads (one of which was Ridley's new road bike), but this TT model was sealed until today's stage.

Ridley's current time trial bike, the Dean, has been around for quite some time, and the design has not changed much since at least the updated Dean FAST version was launched in 2013.

The Dean features rim brakes tucked under the front fork and rear chainstays and a Forza-integrated cockpit; at the Tour de Romandie prologue time trial in April, Lotto Destony riders were also riding rim brake-equipped Dean model. This is the very same stage where Rui Costa suffered a disastrous mechanical failure.

The new bike or prototype bike is most likely an updated Dean model. Given the brand's tendency to only have one TT/tri model in its lineup, it is likely that it will bear the Dean name.

De Gendt and Campaneltz were riding new frames, but De Gendt's bike had a white Ridley logo on the downtube, while Campaneltz's model did not. Campaneltz is a detail-oriented rider when it comes to bike setup, and Deda's TT extensions were different.

Otherwise, the bikes were equipped with disc brakes and appeared to feature an integrated handlebar stem built around the bike's head tube. Compared to the horizontal top tube of the previous model, the top tube is sloped and the head tube profile is deeper. The front wheel appears to be slightly further away from the downtube.

At the rear of the bike, the seatstays have been lowered further and the aero seatpost has a distinctly different shape. It is clear that this is not just an update, but a full overhaul.

As far as components go, the bikes feature a Dura-Ace 12-speed di2 groupset, while De Gendt used the older Dura-Ace 9100 chainset with 4iiiii rotor chainrings, with both riders wearing gold KMC chains. The wheels were DT Swiss and the tires were Vittoria.
