Just out of interest

Has this ever happened to anyone.

I just dropped my daughter of at school. And started to ride going down hill towards a roundabout when I heard a funny noise so I pulled over to investigate and found this. Was not a very nice walk back home lugging the bike. Nearly gave some old gent a heart attack as well as the inner tube exploded half way back had to explain to him that we were not under attack.

its either worn due to braking, a cheap very low quality wheel or both.
Either way you are looking at a new rim/wheel.

was it a loud bang? I had my tyre explode the other day as I suspect I over inflated it, must have gone over the 120psi mark, at that preasure its a BIG bang, scared the carp out of me

I've not had anything as extreme but I had a rear rim failure a few months back. I had known it was worn (indicator had gone) but had forgotten about it . Topped it up to 85psi one night got on the bike the next morning and after about 5 minutes the resistance became immense (surely this hill is not that steep ), a massive bulge had developed in the rim. I unhooked the v brakes to release the resistance only to have it pop a few seconds later.

Same sort of basic,I was pumping the tyre up and the rim went like that,although the wheel had been used for ten years.

Yeah it was a bloody loud bang scared the crap out of me. The rim is totally gone I think it might have been air pressure I did pump up the tyre yesterday so I am thinking that was to blame.

"Deuxieme" bicycle rim gauge. £5 from eBay.

My Open Pros start off at about 1.7-1.9mm. After 10,000km they're down to 1.0mm. They'll get binned when they get close to 0.5mm.

I check them every time I change the tyre (about every 5000km).
