Driving home this evening I was caught in a short queue on a dual carriageway approaching a roundabout with pedestrian crossing adjacent. I spied, across the far side, a youth on bike aiming to cross the dual carriageway come to a not too graceful halt, deploying feet to the ground and slinging his bike around, as the red man sign was on.
Hmm, was this the not uncommon disconnected V brake syndrome found on poorly maintained bikes? As the traffic crept forward I got another glimpse of his bike.
No tell tale V brake arms wagging in the breeze. Hmm, the thick plottens. I look again and spy a disc brake calliper on the front fork. I look harder and do not see a disc braked wheel but a rim braked wheel. Ah, that could explain things.
