Tsk... and people wonder if us riding this old metal extensively is safe. Looks safer than the modern stuff!
Mind you the percentage failure is minuscule.

0.6% failure rate is not miniscule. Imagine if 0.6% of car lug nuts failed. Assuming 5 nuts per wheel, they'd be falling off every 8⅓ cars that went by.
Streets would be littered with literally millions of lugnuts all over the UK!

Imagine if your chain's links or pins had a 0.6% failure rate. They'd basically be failing all the time!

If they've sold half a million chainsets, that's 3000 failures. Not that miniscule in absolute terms.
Just one failure could lead to serious injury or worse. Not good in either a social or business sense

I'd seen a couple of articles about Hollowtech cranks breaking and had wondered if it was widespread or only happened if the chainset had been subject to abuse that it wasn't designed to take.

Suppose there is a point where the balance between lightness and durability tips too far. Not many people can afford or expect to replace major components regularly. Maybe different if you are a sponsored race team.

4519 as stated in the article out of >750k USA (2.8M worldwide), over 11 years.


Unsure if 4519 is just USA since it's a USCPSC document or worldwide reports (not linked in the article for some reason, not going to search it out)
And of course that's just officially recorded.

This happened to a 70 year old cyclist I was riding with, it split and left him with half the crank attached to his shoe and the other half still on the bike! No warning but luckily no harm
