Others may be "loving" this thread, but I'm finding it a bit mystifying.  

First, I've owned a lot of different brakes in the past 35 years and with 
two exceptions they all provided both good stoping and good modulation.  I 
don't know why I would want to switch to V brakes to get better stopping. 
 My wife and I have each had bikes with V brakes which offered good 
stopping, but weren't any better than the Superbe Pros she currently uses, 
or my Campy Grand Sports, both of these are ancient single pivot designs.

The two sets of brakes that I have had that were sub par were both cantis 
-Shimano 550s and the original Dia Compes on my Trek 620, about which the 
last post offered a blog.  I suspect that both of these brakes were 
designed with MTB levers in mind.  The Shimano were particularly horrendous 
to set up and use with Ultegra brifters.  So I  wonder if some of the 
really bad experience people have had with cantis is because they have been 
mated to levers which were optimized for short reach  side pulls.

I replaced the original Trek 620 brakes with the Campy Grand Sport.  I 
can't for the life of me figure out why Trek sold a so called touring bike 
with mediocre canti brakes, a 57 mm brake reach, and barely enough 
clearance for 32 mm tires & fenders.  But it is a great riding frame.

While I'm on this subject the older single pivot brakes give much better 
fender clearance than modern dual pivots and I would suggest it as an 
option to people who find their dual pivot brakes crowding their fenders. 
 About the only brake I wouldn't consider using today is a dual pivot side 
pull, despite how easy they are to set up.

As for cantis, in addition to being just as sensitive to brake line pull as 
V brakes, I can't help but wonder if too many of us have been subjected to 
low cost cantis which proved hard to set up and offered inadequate power? 
 After sliding into the back of a truck I abandoned my Shimano brakes and 
levers and installed Paul's neo retros and Cane Creek levers.  Soon after I 
made a panic stop from under 20 mph to avoid a right hook.  I stopped on 
the dime and lifted the rear wheel about three inches off the ground.  I 
can't ask for more than that from a brake.  

In short, make sure the cantis you are installing really are designed for 
road levers, ( I now use levers with built in releases exclusively - either 
Campy or Cane Creek.)  Learn how to set them up.  Paul's brakes, which I 
have on three bikes, are expensive and the set up is a little different. 
 But they will last forever, stay aligned beautifully and, once you learn 
how, are a breeze to adjust.

happy trails,
Michael
