Are those noises normal in a carbon bike, do all bikes creak a bit but when carbon it is just more pronounced? Perhaps parts are still settling in a bit but I do have a few hundred miles on the bike now. In general I have noticed the "sound" of the bike is quite different then other/past aluminum bikes I have ridden.
Thanks.
I can't talk about carbon frames as I have a Sirrus 3.0 - but I was hearing sporadic noises and finally pinpointed it to the bottom bracket being loose to the point of being able to move the whole assembly side to side about 1/4". Turns out was a factory recall and the LBS corrected it.
