Good to know! I never tried it. Were the Raids at all compromised from being on bosses ~10 mm narrower than they were made for? Other than maybe fender clearance, or getting a really fat tire out, I guess the braking would be identical -- the brake doesn't know or care how wide the posts are.

Right before I left home to go visit my mother, what I was working on was adding Raid pivots to an old ('50s) fork with a crown that's narrower than Raid bosses "want" to be. To put the posts 75 mm apart, the miters were going to be partial, as in having an opening on the sides, because they're so much wider than the blades. Maybe I'll miter them more on-center with the blades to get full contact all the way around, if the brakes work just as well. That bike will have 42 mm tires on narrow rims. Will the brake still let a 42 out? I can test it easily, just mount the Raid arms on a Racer étrier, so I guess I'm just asking in case you know off the top of your head.
