Gernot,
Your photo and explanation make it very clear. You'e even answered what
would have been my next question about the Harris Cyclery statement "This
can solve a number of problems..."

You can probably get the reach you need with a recessed brake bolt
from a standard road caliper, although the Sheldon nuts may be what
you would want with the fender.

2010-03-12 Thread MichaelH
I had the shimano Br 550 cantis and found I could control the squeal,
but setup was aweful and stopping power very poor.  After a near death
experience, compliments of shimano, I bought the Neo Retros and have
loved everything about them.  I no longer think about buying any other
brand of brake for any of my bikes.  The only thing I have ever had as
good are a pair of early Chorus short reach.   When the new standard
reach version of the Racer is available I will buy it for my
Rambouillet.

That would never work for me.  Right now, the Hillborne has Tektro 720
brakes and the front straddle hanger is a good two inches higher than
in that photo.  Just slightly under the headbadge.

In that setup, the hanger clears everything, Nitto rack, front fender,
and even the back of the Lil' Loafer.  When lower, was actually
catching on the leather of the bag.

[RBW] Re: brakes on the atlantis

2010-03-11 Thread Earl Grey
Look at http://www.flickr.com/photos/25150...@n08/4426738206/

The long bolt goes through your fork crown, and the forged part rises
up from it to accept the cable housing. The idea is that flex between
cantilever bosses and cable hanger are minimized. As braking force is
applied, the forks bend back slightly, which tightens the brake cable,
which causes the brake to engage more strongly, until it breaks free
and the cycle is repeated. By moving the brake hanger closer to the
fork this flex and the resulting squeal is minimized.

Let me know if this is still unclear.

[RBW] Re: brakes on the atlantis

2010-03-11 Thread Earl Grey
I had squealing with BR550s on an Indy Fab Planet X. Finally solved
with massive toe OUT. Toe in didn't do squat.

Have Tektro 720s on my Hillborne. Using a fork crown mounted Tektro
cable hanger, no squeal, without any toe in. Switched to a regular
headset mounted cable hanger, instant squeal, even after adjust toe in
a couple of times to pretty extreme levels. Switched pads to VO no
squeal, squeal gone. We'll see how long they last.

The hanger I am talking about is item CAH59 on
http://www.sheldonbrown.com/harris/cable-hardware-brake.html

The Tektro fork crown mounted cable hanger is a god-send, but I had to
give it up because I installed a Nitto front rack AND fenders, and the
bolt on the rack is not quite long enough to accommodate everything.
Briefly thought of attaching the front fender L-bracket inside the
fork crown to shorten the stack, but that seemed overly fiddly. If the
VO pads wear too fast, perhaps I will resort to this option after all.

[RBW] Re: brakes on the atlantis

2010-03-09 Thread Angus
Seth,

I have a set of Mafacs and have the same experience as you...no
squeal.

I have a set of Mafac copies (similar geometry) and they squealed and
vibrated, a toe in adjustment (wrench) and they merely vibrated.

They were quite loose on the cantilever post, the Mafacs are
noticeably tighter.  I don't have Pauls, but the look like they may
not use the cantilever post as a bearing surface like the Mafacs do.

Back when I had an Atlantis, it had Paul Touring front and rear.
They'd squeal, adjust toe in, no squeal.
You do have to adjust to the toe in as the pads wear.
I toss the cheesy hangers they come with a get some Mafac
hangers from a 1st class LBS, adds a little humor.
The Cafams are cheaper and look it and feel it.

yes, all brakes need to be set up correctly to minimize squeal.
Somtimes the fork design can be a factor, but the Rivendell bikes have
pretty beefy forks so that should not be an issue.
I also have had good luck with the Tektro CR720's.

I started with the Paul Touring canti's on my Hillborne. No squealing
right out of the box and they stop very well. Can't say that about the
Avids on my Soma.. always playing with the front.  You should also
consider IRD Cafam. Very similar to the Paul neo-retros at a lower
price point... but not MUSA.
