I took my bike in for a service over Christmas at a local bike shop (that also used to sponsor my club) asking the guy to take a look at the drive train and bottom bracket. Later noticing the drive chain was filthy, I made a mental note to take it back and have a word, but what with kids and all I never got round to it.
Today on the way to work I heard a clunk as something stopped working in the rear mech (there was nothing on the road it's self to get caught), within seconds it'd all got jammed and the mech came a part under the strain, and the hanger got deformed too.
What can i do now, Ought I ask them to take some responsibility, or have is it fair enough a month later? What do we all expect from a bike 'service'?
