Sett valley cycles - great shop bit roadie oriented but Sam & stu know their shit when it comes any kind of bikes, prompt repairs too : ) 8quid for a wheel true mini service.
Freeride cycles - again cracking shop, one of the bigger ones but doesn't stock the biggest range of spare, good repairs but not the quickest but go above & beyond.
In-gear in poynton is supposed to be pretty good - stu from sett valley works there.
Bicycle smithy - miserable twunt, some people really shouldn't work in costumer services....
Royals wilmslow - pretty good shop, but shite for repairs & can sell oil to the Arabs.
NWMTB - great shop, loads of spares but only had luck with dieter one of the mechs..
