Cannondale CAAD4 Components(7 posts)

I have a Cannondale CAAD4 frame on order and will outfit it with Ultegra components (double crankset). What type of Front Derailer do I need -- Clamp or Braze-on? Any special considerations given the large-diameter downtube?

Cannondales use a 31.8 mm clamp on derailleur. My bike (a Cad 3) came with a braze on front derailleur with a shimano braze on clamp.

Just built one up this week...Matno

One "special consideration" with relation to the large downtube is that the derailleur cables are very close to the tube. I'm not sure if there's a way around this, but when my bike's on the stand, the front derailler cable "slaps" the downtube with a loud twang every time I shift it down. Didn't notice that when I actually rode it outside (I've only ridden it once so far), but it's annoying on the stand. Maybe some rubber cable "washers" or some protective adhesive tape on the bottom of the downtube might be in order.

Other than that, I can't think of any potential problems that would have anything to do with the oversized downtube.
After nearly a year on a CAAD4, I've never noticed a twang (nm)czardonic

Yeah, I'm not sure why it did that...Matno

Could just be my new shifter and derailleur getting broken in. Like I said, it didn't do it when I was out riding. I think the way I had my front derailleur adjusted might have been making it "catch" on the chain and chainring and then kind of snap together. Nothing I'm particularly worried about, and it seems to have gone away now that everything is dialed in a little better. (I'm still waiting on barrel adjusters for my derailleurs. They didn't come with my frame, and my local C'dale dealer is a moron. Didn't even know what I was talking about. I had to show him some on a bike, and then he insisted that it was impossible to get separately. I guess I'll have to take him the part number listed right on the C'dale website...)
Actually, I'm not the only one with that problem...Matno

I just read through the reviews and found 2 or 3 other people who complained of the same problem. I wonder what the difference is?

Mine is full Tiagra, which doesn't seem to be too common.
