Catastrophic crank fail

I'd previously thought sugino messengers had a good rep, but sounds like theres been quite a few failures, albeit all have propagated over time as far as I'm concerned it shouldn't happen!*

*if you are using the right crank for the right job. e.g. if you were using a super lightweight touring/ racing crank I would not expect it to put up with years of abusive fixed/ single/ out of the saddle riding.

I used to ride DH/mtb a LOT, probably out 30hours a week or more on my bike doing various things and I've never had a crank fail, not even shitbox OE ones that I'd borrowed from a mate (when a gen1 hollowtech bb failed after a few weeks of use). Between our group of riders we would tend to buy the same kit, as you do, one guy gets something new, then the others would want. ANd from teh larger commuinity if we had a repetitive failure, cranks/pedal axles/ suspension linkages/forks/ h'bars etc we would as a group ditch the product and move on.

What I'm saying is, why has Sugino themselves not responded to a number of their messenger cranks snapping through general use leading to various minor accidents (thankfully none more serious yet)?

had the same thought
