I just ordered a pinhead set of skewers, headset and seatpost locks . I noticed that the only exposed bolts are my rack and saddles bolts.

I found a security bolt that uses a combination lock built into the head of the bolt, but it's from Germany and would cost me $50ish or more to get the one bolt plus shipping.

I figured the security torx bolts would be enough of a deterrent

Thoughts?
