So my first bike built by the halfords "experts" was brought out with two buckled wheels and I was told I can get it sorted the following week.. I hadn't even ridden my vengeance yet and it was broken. After the period the axle had become bent and they decided to give me a new bike. When I got the bike the wheels were ok, I had to straighten the handlebars and seat, but everything else seemed ok. I just wish I'd checked something very fundamental and safety critical.. that the wheels were tightened and werent likely to fall off.. which they did. Twisted my ankle but managed to get the bike back. Hopefully halfords in Cambridge will take it as a lesson to teach their "experts" how to build a bike before it puts somebody in serious danger.
