All I can say is I have a 53/39 on my TT bike and it is great. I can climb hills on it, I can wind up into a big gear on the flat.

On my road race bike I have a 50/34 compact... I climb hills more quickly on that because I spin and not grind so much (I'm a slow climber still). My only issue with it is trying to find the right gear when I am in the middle at the front and back...

They are both fab gearing. The compact would not be a good TT set-up for me, but it is ideal for road racing.

Dunno if that helps any, but thats my experience.
