New at this forum but been lurking for a long time. I'm 33yrs old and from Belgium.
My 2013 Caad10 also started to creak at the crank after a few rides.
I'm a presision mechanical engineer with 15years professional experience in manufactering parts for automobile and pharmacutical industry.
I dissasembled the bearing and did some measuring. Contact surface roundness was seriously out of tolerance. With some specialty tools I reamed the hole in the frame and remounted the same bearing with a liberal amount of teflon grease. Problem solved and still creak free after 5000kms.
Asian low budget manufactering quality...
My suggestion: If you ride a bike, start to learn how to fix it and stop crying like babies or go walking.
