Canti brake for 27->700 conversion

Anyone know of a canti with a very low pad postion?

I've a fork off of a 27" wheeled Cannondale that I would really like to use with my 700 dynamo wheel. Right now I have a low-profile STX that just barely works. The pads are arcing downwards a bit more than I would like. I figure I'll file the slot a touch lower if I can't find anything else.

Pauls or early XT would likely work. These are the usual answers. I'm sure someone will answer with a more definitive answer,

Or you could always try V-brakes, which typically have more pad adjustment.

I used (the stock, in this case) Dia Compe 981s to good effect. Check out this thread: http://www.bikeforums.net/classic-vi...-failures.html

The secret is to rotate the brake arms way out and away from wheel, which will locate the pads lower. With these brakes on this bike (see pics in above thread) I have solid braking. But this is an around-town gravel-grinder sort of bike. Test braking carefully on a loaded tourer.

Edit: Since the photos I've shortened the straddle cable, which gave a more confident brake feel. You can change the length which changes the angle and leverage to finetune the braking feel.

Ha! I was looking for that thread, since I started it and had success with the Tektro 720 cantis going down to 700c on bike that was made for 27s. I do ride that bike often and don't waste a moment's thought on the brakes, now. Pics show it worked, but it's not a 'perfect' fit. The brakes work just fine and will actually fit better when the pads have worn down a bit

It's a grinder and a grocery getter; not a show pony.

@Dylansbob, pls post your own results to that thread when you're done with your build. It's a subject that comes up a lot on these forums and I think it's worthwhile to keep track of numbers and measurements for future reference. Not just the "X cantis worked fine on converting Y frame from 27 to 700" but some insight on why they they worked out, as well.
