Don't make the same mistake I did and trust Halfords with a 'simple' bike build. Pay the extra few pound and take it to a business that can build the bike without actually damaging the bike. Ok sometimes things happen but to damage the bike and then fit parts on I didn't ask for, then that's different. They also lied about contacting me regarding the fitting of the new parts. That did not happen Halfords! After talking to the Inverness branch on the phone about the matter they hang up on me. All in all a really poor service from Halfords and the Inverness branch in particular. Emailed customer services more than 5 weeks ago and to date did not even get a response. Just goes to show they don't care. I don't usually write a review or complain for that matter, but no response leaves me no option but to write this comment.
