what you need to do is make sure they haven't taken any of the components off and replaced them with cheaper ones, also if you know about about bike Assembly do it yourself instead of having them do it.
I am getting a new bike soon and I want a GT Chucker XS1 which they sell at Halfords for £379. Its a good deal and it has hydraulic disk brakes, RST Launch forks etc. Alot for only £379. I am just hesitant because Halfords has an awful reputation.
