The other problem with switching to compact is that you need a new front deraileur, and some bikes, like mine, used a welded boss that doesn't reach that low. ...then there' s the complaints all over about after the change, they have shifting problems, a lot more hassle than just choosing my 11-23, 12-25, or 13 -29 cassette.
Sounds like someone is blowing smoke up your...
The only complaint I've ever heard from someone with a compact is that they regret waiting so long to try one. Oh, that's from people who I talk to in person. Y'know, real people. Not ones that say they push 55-11 up 10% grades on their magical carbon fiber uber machines built by elves in Switzerland. I love my compact. Keep loving what you ride. But don't try to justify why your set up is soooo much better with made up reasons and questionable logic.
