Tried searching for it but 'compact crank' is too much a generic term.
Anyways, my current drive train is Dura Ace 7800. I would like to swap the 53/39 with a compact, because next year I'll be getting older and the darn 15%+ hills I love so much will not be getting any shallower.
The current Dura Ace compact is expensive as hell. What the **** is there that makes it worthy of the price tag?
The Ultegra is half the price tag. Besides the fact that it doesn't say 'Dura Ace' on it, why is this so?
And of course, for that kind of money, what else should I look at?
Your expertise on this would be greatly appreciated. Thanks in advance.
