It's possible I s'pose, but it had been rigid for the 8 months I've had this bike. Unless the bike shop ****ed up the freewheel cog fitting in a rush job - I wouldn't be surprised if they were getting pissed off with me as I'd complained in writing and been in four times with a recurring issue (broken bearings after 8 weeks) that I was adamant they should fix (and eventually got them to do a changeover free of charge).
