Unlucky fella :( .

A design flaw of the early Middleburns, they addressed the problem by rotating the orientation of the square taper. Very good cranks nowadays.

I've been using a set of RS3's on my old single speed for quite a few years without any problems but I have heard of more than a few failures with these older cranks. Not something you would want to happen 20 miles from home... :evil:

Yup, anyone running any make of cranks with the tapered hole orientated this way needs to examine them regularly or be prepared to take a flight :)
