I love riding my carbon fiber Orbea Avant. It has a fine ride and handling with impeccable balance. It also has more noise than any of my other 4 bikes. I have eliminated most of what used to really irritate me with re-cabling including slick lube liner through the entire frame, new Shimano bb and crankset to replace the original FSA, and fiddling with the cable/housing positioning from the 5700 brifters.
The drivetrain still creates some resonance through the cf frame, and there is still very minor rattling on rough pavement, but I don’t notice it much anymore after being on the bike for a while.
