Blimey...that's not good is it?
As usual though, Halfords is very hit and miss when it comes to bikes.
Yeah they're crap. And not just when it comes to bikes either.
I tried to unscrew the screw & the head started to disintegrate. Told my brother if he has one more problem with it to get his money back & go to lbs down the road
Its a halfords bike, it WILL have more problems. Totally avoid halfords in future, they give bikes cancer.
