Typically Cannondales are poorly spec'd.

Coda components (as alienspore mentioned) are the C'dale in- house brand. Strangely enough these components even seem to be spec'd on thier top bikes. They are typically junk, and most definitely dont belong on CAAD5 frames and up.

When you buy a Cannondale you are paying for the frame. I personally think there are better manufacturers out there, but the frames are nice.

I've been a C'dale fan for a long time, and I would without hesitation agree the less Coda componentry the better. I'll go as far to say I'd see if I could get the LBS to switch it as part of the deal. Especially the cranks. The frameset on the other hand is hard to beat.
