Clipless. Every bike, every ride.

I like Shimano's A-520, single-sided "road/touring" SPD. They just work better for me than the double-sided MTB SPDs. (No doubt an operator problem.) My only gripe with them is that I get only 10,000 to 12,000 miles out of the bearings, and it takes 700 miles to break in a new set so that they flop right when I unclip.
