Today was supposed to be fourth in a series of short mountain bike rides to gently get my foot/ankle working properly again. (On a mountain bike but largely on-road.) Less than 10 minutes out, there was an immense ‘bang’ the like of which I’ve never heard from a bike before, and I was riding on a flat back tyre.
I have never experienced a rim failure before. The strip of metal in the photo is a chunk of Mavic rim side wall. The photo of the wheel shows the missing portion. It just blew off – the strip of metal was on the road. Whether that was some kind of impact-related failure – but no pot-holes were involved on the day – or a result of longer term wear and tear I don’t know. That wheel set has only done about 4,000 miles.
I’m not sure how I feel about it. I’m glad it wasn’t a front wheel, glad I wasn’t far from home, glad that a neighbour happened to be just along the road and he could give me a lift home (thanks Roger). But should it have failed? Is that reasonable?
