Those pinheads are good for securing stuff - if you have QR axles.

The "key" is a problem, it's about 1-1.5" long so you'll have a **** hard time getting any sort of reasonable clamping force if you don't have vert dropouts.

Seats, cranks and bars can still be stolen with both systems. And pedals. Basically if you lock your bike anywhere you're taking a chance either way.

No rain for me today, hopped on the go train.... went past a bunch of stuff that was heavily t-storming, got up to the hill and it was perfectly dry up here. woopee!
