Did *you* ever actually ride a bicycle using properly setup Deltas,
Tom? Or are you taking Herr Perfessur Brandt's word on this? You know,
I finally got him to admit that he had only taken *one* brief ride on
Deltas, in pretty much an urban setting. So he's talking through his
a** on this subject. No surprise there, IMO.

Thanks for that! they look interesting. I wonder if some of the
problems might not de solved with levers havin lower mechanical

IMO, brakes lacking in modulation function more like an "on/off
switch", going from zero to full braking force with little in between.

If the function is not linear, a decreasing ratio of force applied at
the braking surface for a higher applied force at the lever would be
desirable, unless you like the idea of pitching cyclists over the bars
or causing them to crash from the front wheel sliding (off-road, wet
pavement, etc.). "Self-energizing" brakes such as drum brakes and
Campy Delta brakes are undesirable for this reason....

Modulation is the ability to vary braking force. An ideal brake would
have the braking force applied at the rim vary linearly with force
applied to the brake lever.

I don't know about that. A functional curve where the brake applies
more force as you increase pull might be a better design. That is,
fine graduation up front and less later on.

Think of it as similar to the way a volume control works on a stereo
system: it's wound (or at least still designed) so that you can get
fine graduations in sound level and lower volumes, but as you reach
high levels that becomes insignificant and the increase rate
increases.

Brakes like that have been tried and abandoned. See for instance the
Scott-Pederson self energizing cantilevers that were popular for a while
in the 80s.

All my brakes have been more or less linear (calipers, V brakes, discs)
or regressive (centerpull cantilevers) so I'm just speculating here. But
there are enough situations where fine control during moderate to hard
braking is useful, especially in mountain biking, that I'm skeptical
about the value of progressive brakes.

The old Shimano "Servo Wave" brake levers did something a little like
what you describe, although the intent was more to bring the pads to the
rim quickly than to provide progressive braking. Those too have fallen
by the wayside.

I'll take a linear force over progressive any day.

?Huh? You called them "a set of prototype dual pivot brakes". Which
are they, single pivot or dual pivot?

And, "no modulation at all" doesn't sound very attractive, whatever
the design.

They're single pivot with a bell crank arrangement to increase leverage.

I didn't understand what you meant by "modulation". In automotive brakes
the term would indicate some kind of pulsation in the braking system.

The pads were too new and I was using them on a fairly new set of Mavic
Open Pro rims with rough machined sides so it was hard to tell how
controllable they would be.

I gave them a good workout today and yes they are very controllable but
they're the first road brakes that I've been able to lock up since I
started riding again last year. I have to remember the old trick of
sliding back on the seat in a hard stop - they will definitely throw you
forward.

This afternoon I had a minivan pull in front of me and stop. With any of
the brakes on my other road bikes I would have mated with the back door.

Dig up a pair of CLB2 centerpull's if your looking for a brake with
the ability to lock up your wheel.

Do they "stop better", or do they offer less modulation? IMO, grabby
brakes aren't too attractive.

There is no modulation at all. They have very high gripping power. They
are single pivot but they work like dual pivot.

I have centerpulls on my vintage Motobecane. When the uninitiated ask
about "those strange brakes", I put tongue in cheek and refer to them
as ' long reach center actuated dual pivot brakes'. :-)

I asked just that the last time this brake was posted and, I believe, Mr

Center pull brakes stopped better than the sidepulls of the day but Campy
sidepulls with their beautiful satin finish looked so much more sexy than
Mafac or Weinmann CPs.

Didn't Campy threaten to bring out centerpulls in the mid 70s?

I realized that my brakes weren't stopping as well as they used to then I
realized that I weigh about 30-40 Lbs. more than I used to too!

I've been trying some different brake blocks on the sidepulls on my retro
bikes. On one of my bikes I have a set of Mafac Competition 2000 brakes
with blocks that go back to the early 1980s. These still stop better than
all of the different modern blocks I've used on the retro brakes.

Last weekend I replaced the Dura-Ace sidepulls on one of my bikes with a
set of prototype dual pivot brakes. They stop better than cantis, U-brakes
or V-brakes. I have to be careful that I don't end up doing a face plant.

What's old is new again-- centerpulls with the pivots brazed-on.

Paul Component Engineering offers these as their "Racer" brake, and have
lately offered a center-bolt version as well. Think Mafac, but with
modern materials. Very nice, but super-pricey.

I want.
