I should clarify that I am not really shopping for a lock. The idea for this thread came about because I was considering removing the generic cable lock from my seat post, as I never use it and all it really does is scratch the hell out of my inner thighs.

What I was looking to do was to generate some conversation about simpler ways to secure a bike, specifically by securing the cranks. Perhaps by putting this challenge out there, someone will invent the next billion dollar bicycle accessory.
