Size is 58cm; in truth it was a little large for me (I’m 1.78m/5ft 10″)
Crikey, I am about the same height as you and had a 56cm which felt a touch too long, I had to run a 90mm stem on it. My current Equilibrium is a 54cm with a 110mm and it feels much more controlled.
The cherry red is definitely the best colour though, I like my bronze but a bloke at work still has a red one and I look at it with lustful eyes.
