I've never ridden hard enough to break anything on a bike.

Never broke anything but chains at the dragstrip, seen plenty of others have failures and chocked it mostly up to lack of understanding on their part.

Fail to plan, plan to fail.

I have always had a very good sense of what can, will go wrong and evaluated things with a practical, critical eye and process.

All of my cranks will likely outlast me by a long shot.
