In this bonus episode of Geek Warning, Ronan McLaughlin sits down with the Colnago design team to dissect the design and development of their latest aero road bike, the Y1-RS.

They explore how recent changes to UCI regulations opened up new possibilities in frame design, the challenges of balancing aerodynamics, stiffness, and rider comfort, and why the bike looks the way it does.

The discussion covers everything from improving CFD modelling to a Colnago's stiffness tests, and the whys of that off set seat post design and Y shaped handlebar. Long story short… In the absence of being able to ride the bike, we set about finding out if this decisive bike is all go or all show.
