I have a pair of Shimano M520 SPD's on my commuter, with over 20,000 all-weather miles on them. I cleaned and re-packed the bearings at 10,000 and they're doing just fine, no signs of wear. I might re-pack the bearings again just to be sure.
There are 10 types of people in the world - the ones that can count in base 2, the ones that can't count in base 2, and the ones that didn't expect this to be in base 3.
