Any of the four CCE/cycley parents of kids at my school(all in the same class,spookily) may know this already, but the gym teacher's bike was sabotaged by front QR loosening some months ago. Poor guy needed hospital.
I think they/he/she struck again because the titular nut is missing from mine, and I doubt it could have come off itself. I tightened it up on Thursday, so I am not surehow it got loose enough to be undone by hand. Cold and contraction maybe?
I noticed the bike was sounding different on dropping, which I put down to studs in the guard, so I rode from the school to home on the horrendously slippy Lasswade path on Friday before noticing the real cause today, testament to how well the other nut was cranked on.
Anyway, I need a new one. Where best to go?
