I'm saying that haven't never used compact cranks and the 39/27 combination has got me through a few Alpine Classics and Baw Baw etc,. of course there must be advantages/dis to using compacts.
I'm going to the argue the opposite - I reckon compact cranks should be the default. Most people aren't racing and don't need 53/11 (nor racing geometry for that matter). Of course getting people to admit that they aren't racing and aren't ever going to race may be the challenge.
Personally I've been riding around on my compact w/11-28 for years (originally w/12-27) and never found any real disadvantage for casual riding. I did start racing about a year ago and so now I have a bike with racing geometry and 53/39 cranks (and 12-25 cassette). I won't be taking it on the Alpine though because it's not a good choice for that kind of ride.
