Incredible response with a lot of great information and ideas for me
to try. Thanks everyone.

Not just angle, but also conditions. Today went for a 10 mile ride in
a pretty serious winter storm. On downhills the front brake was not
just useless, but dangerous. Got serious washout/lockup just touching
it. Packed snow/ice will do that.

I'm glad this came up, as i've been fighting slop in my front wheel
for weeks and nearly destroyed my headset in the process. Now i think
it could be what's described here (having not used cantis in a long
time). For the fork crown hanger, i already have lots of stuff
through my front fork crown

Funny you mention it. My most epic battles with shudder was on an
Indy Fab also. At the time I hadn't learned about the crown hanger
solution, but knowing it wasn't drilled excuses my ignorance (at least
in my mind). I ended up just selling it, around the time the

However, on a bike that had no through-hole through the fork crown

Excellent explanation Jim.
I've had the same problem with tektro 720's on my ti rando with a ti
fork.
I played with different hangers, longer stem cable stop, changed the
height of the hanger to shorten the amount of exposed cable between
the stem cable stop and the hanger, I've toed in my brake sh

This topic comes up repeatedly. The discussions typically focus on
treatment, which is natural, because you just want the thing to go
away. But understanding the cause is usually helpful in figuring out
the treatment. The cause is as follows:
You grab your front brake, which tries to stop the w
My experience is the same as Angus's. My CR720's fit very loosely on
the studs and when the pads contact the rim they pivot on the studs
enough to go toe out if you do not set up the pads to be toe-in under
contact and rotational load. Cured the violent low-speed shudder for
me.

I had a set or Ribbit (typical Cyclocross brakes, Mafac copies) on my
Atlantis that did a very similar thing.
I am not familiar with Paul's brakes so this may not apply (some
brakes have an internal bushing and don't have a bushing riding
directly on the cantilever post on the frame). Also Jim ma
