I think Joe was talking about the in/out adjustability of post-style pads, which have a greater
range than the bolt-on bads. This isn't much of an issue, but I've seen cases where it would help
like the recent case of a Bike Friday with Vee brakes. Brake posts are very wide on the rear of this
bike and with the washers setup so the pads were in as far as possible, they still weren't nearly
far enough. I don't have a bolt-on pad handy so I can't measure, but I'm looking at a post-style and
my impression is that it'd go in quite a bit further. Of course, this setup isn't ideal (brings more
flex into the system) ....

Slip-in pads makes the easy adjustability of bolt-style pads kinda redundant, I think. These
would've helped immensly in the days of centerpull cantilevers.

Me three!
