I had crashed a a week or so before they broke.
That's why I'd never use Carbon for MTBing.
I don't trust it for any type of riding where impact is highly likely.
I assume you were racing?
Here's my plan (and part of the reason I got the CAAD9 in the first place)...
Eventually, I'm going to build a custom carbon bike that'll be my dream bike for nice Sunday rides. It'll be my "cabin fever cure" project.
The parts I want to put on the CAAD for now are to get rid of the poor performance OEM bits and to get the most out of the CAAD.
When I've purchased a nice frameset, I'll swap the cockpit over and replace it with all aluminum (I'm partial to Deda stem/post/bar).
The CAAD I'll build up for training and for racing possibly and the plastic bike will be my uber bike for Sundays or Centuries.
I liken it to having a Corvette to romp & rip with (The CAAD) and a Ferrari for GTing (the uber- bike).
So right now, I could get a great cockpit, use it on my current bike,
get all the benefits of the upgrade and have a better riding experience.
If it was all about comfort, the CAAD would certainly "not" be on my list.
I'm not trying to turn my CAAD into a HI MOD Ultimate or a Synapse.
