I'll be picking up my '84 520 this evening. I've been saving this set of brakes to try on it. They have some adjustment and I can dremmel a bit if I need to. If that doesn't work I'd be interested in how you removed your canti mounts.

Swen0171, the 27" tire selection is small, but Panaracer makes the Pasela Tourguard in 27x1 1/8 (28.5mm) and 1 1/4 (31.75). That's a pretty good tire for a touring bike if you ask me. I'll be putting them on the two vintage touring bikes I just purchased. Keeping the cantis and 27s!

It seems like a better solution in the second pic, adjusting the pads down seems to move the cantis to a wider style. I wonder how the springs like that.
I can't tell on the third but it looks good, though on both the second and third, I wonder if you can get a better response from the cantis using mtb style brake levers and the extra force from the lever helps with the mis-aligned pads?
I'm glad you found a way to make it work, my point is that it is not a simple switch and works against the design of the brakes.

couldn't something like this be used with the stock canti bosses when going from a 27" to 700c wheel?
I actually have a set of them on a Trek 7300 Multi-Track in the garage. I guess I can pull them off and try it this weekend.

Out of curiosity. Shouldn't a frame Builder be able to perhaps remove the bosses, and then re-attach them a half inch or so lower? That'd leave you with a frame that looks original, or nearly, but also allow you to mount 700c wheels?

Having pulled the 700c wheel off my 7300 last night I now have a better understanding for the problem.

you can actually take any old frame and throw some canti bosses on them. however, this requires a repaint. i just did this to another frame with 27" wheels and no original cantis.
