[RBW] Re: Cantilever brake question...

[Garth]

FWIW, Rene's Shimano R600 levers are regular brake only levers , they 
are no different than any mtb or bar end lever in cable pull.   

Everyone is just guessing as to what the issue is and all that we can do 
without seeing it and feeling it in person. I assume his cabling to the 
rear is perfectly clear of all sense of drag, but that also is just an 
assumption. It's gotta be perfect first and foremost :) The easiest way to 
check is to disconnect the brake yoke and hold it in your left and actuate 
the lever with lever in right hand. It ought to be smooth as a hot knife 
through butter. If not the housing end needs some refining.

Jeremy, I didn't read your post as a polemic, but rather as illuminating. 
 My personal experience has been that some road levers, especially Shimano 
SIS, pull too much cable to work effectively with cantis.  My 
recommendation to the OP, before spending any money, call Paul's and talk 
through the problem with them.  They are very customer oriented.  I would 
still bet that the system needs a different set of levers, not a different 
set of brakes.

What Jeremy says also misses the connection between low mechanical advantage 
(necessitating more grip strength) and arm/hand fatigue. There's a reason why 
systems only requiring one finger braking are highly prized for off road 
riding, same would go for any situation in which a rider is braking often or 
while fully loaded.

Jeremy, what you write makes perfect sense and is an excellent distillation 
of what Sheldon has written on the subject. However, in my experience 
theory doesn't always work out under real-world conditions. FWIW, I am a 
large man (6'3", 215#) with big hands (size 8.5 glove) and a strong grip 
(take my word for it). In wet conditions with a heavy load and a steep 
descent I have found Neo-Retros to function more as speed modulators than 
proper brakes, no matter how hard I squeeze. So far I am happier with the 
Touring cantis, but they've only been on the bike for a month or so and 
it's been pretty dry during that time, so it isn't an apples-to-apples 
comparison. The rain is coming though, so stay tuned...

[RBW] Re: Cantilever brake question...

[Bill in Roswell GA]

Ref the Shimano Deore XT V brakes, I just rebuilt a 1997 Klein MTB that 
I've not been on since 2004. I cleaned the brake tracks, sanded the pads 
and was astounded at how great those brakes are (in the dry). Using shorty 
levers, I'm talking one finger operation per brake. A nice feature of the 
old XT Vs is how wide the open, easily clearing 2.2 inch wide tires. 

The old XT V brakes have more stopping power than the Ultegra 6600 
sidepulls I have on a couple of bikes (flex?). Having recently taken a ride 
on a gravel bike with TRP Spyres, I would say the old XT V brakes are only 
a few hairs behind, about equal with Avid BB7s (in the dry). 

On of my riding buddies has Shimano CX-70 canti brakes on his all-rounder 
and those things are pretty awesome with the stock Shimano pads. My CX has 
wide cantis (Kore branded, but a lot like FSAs) with Koolstop CX pads setup 
with low straddle (the way most CX racers run wide cantis) and they are 
pretty good at slowing the bike down, but not as good at stopping. Levers 
are Ultegra 6600 STI.

If you can't run discs and need stopping power the old XT V brakes would be 
hard to beat (having never tried Paul or Compass centerpulls) for the 
money.

Bill in Roswell, GA

[RBW] Re: Cantilever brake question...

[Jeremy Till]

It may help to clarify a few things here, and define terms.  Braking 
"power" is a tricky term, but for the purposes of my post we could define 
it as amount of normal force applied by the brake pad to the rim.  This is 
dependent on the mechanical advantage of the braking system (brake, cables, 
and levers), the spring tension of the brakes, and the grip strength of the 
rider.  For the purposes of this discussion we will ignore secondary 
factors in braking such as cable stretch, housing compression, and brake 
pad friction.  

Mechanical advantage (or leverage) is likewise a tricky term.  It refers 
specifically to how much the braking system multiplies the force applied to 
the brake lever by the rider. Taken simplistically, therefore, it could be 
understood as the main determinant of power, as in "v-brakes are more 
powerful than cantis." However; mechanical advantage is not power for 
nothing; just like a simple lever, in order to taken advantage of leverage, 
we have to apply that power over a distance.  The brake lever travels 
farther than the brake pad over the course of the braking action.  The 
bigger the mechanical advantage of the system, the farther your fingers 
have to travel.  In the end, the power (remember, that's total braking 
force) of high mechanical advantage systems can be limited by the amount of 
travel the lever has between its resting point and bottoming out on the 
handlebar.  Since the brake pad is not moving very far, they also have the 
disadvantage of requiring the brake pads to be run very close to the rim, 
requiring exacting brake adjustment and wheel trueness.  

Low mechanical advantage systems, on the other hand, often are not limited 
by lever travel.  Since the leverage ratio is smaller, the total distance 
the brake lever has to travel is smaller, well within the range of most 
contemporary brake lever designs, even when adjusted for smaller reach.  It 
just means that the force you have to apply to the brake lever in order to 
achieve a given "power" (braking force) is larger than it would be with a 
higher mechanical advantage system.  In other words, it comes down to grip 
strength.  If you have plenty of grip strength and squeeze really hard, a 
low mechanical advantage system can let you achieve very high braking force 
without ever reaching the limits of your brake levers.  They also have the 
advantage of allowing the brake pads to run farther from the rim, so aren't 
as depending on exacting setup and perfectly true wheels.  
.
So in the end, it comes down to the particular rider: the dimensions of 
their hands, their grip strength, and their personal preferences.  If you 
are limited in grip strength, you would probably prefer a high mechanical 
advantage system.  However, given that most riders with lower grip strength 
also have smaller hands and have to limit the reach of their brake levers, 
this means that lever travel becomes the limiting factor in most high 
mechanical advantage systems.  While they multiply hand force more, they 
are limited by how far the brake lever can go before hitting the bar.  They 
have a limit beyond which you cannot physically brake anymore, even if you 
were stronger.   On the the other hand, folks with big hands and  a firm 
handshake can run a low mechanical advantage system, run their brake levers 
as far out as they'll go, and be just fine.  Since the're not limited by 
level travel, they harder they pull, the harder the brakes will press on 
the rim. 

What does this have to do with the braking components offered by Paul? 
 Well, here's the rub (pun intended): I'm fairly certain that the 
mid-profile Touring Canti has more mechanical advantage than the 
high-profile Neo-Retro.  Does that mean that they are absolutely more 
powerful than the Neo-Retros?  Not necessarily; they just create a system 
that is limited more by lever travel than the grip strength of the rider. 
 I have no doubt that a rider with a strong grip could squeeze tons of 
power out of a set of Neo-Retros, the type of fork-bending forces that Paul 
describes in their warning.  On the other hand, if you find that your 
braking force "hits a wall" with Neo-Retros, that you can't pull the lever 
any harder (and it is not bottoming out on the bar) and still aren't 
achieving adequate stopping power, then the higher mechanical advantage 
Touring Cantis might be right for you, both on the front and back.

Paul are amazing machinists and fabricators, who care about longevity and 
serviceability more than a lot of companies in the bike market.  They are 
not necessarily super original when it comes to design, however, especially 
of their brakes.  Pretty much all of their brakes are copies of other brake 
designs, except executed with top notch materials and attention to detail. 
 Paul readily admits that the design of the Neo-Retro was copied from old 
Mafac tandem cantilevers, which back in the pre-MTB days were probably some 
of the most powerful 

[RBW] Re: Cantilever brake question...

[Brian Campbell]

True. These brakes also allow for  27" to 700c conversion pretty easily as 
well on most bike from this era.

Terrible pic, but here is my Clementine with 2" (50mm) tires and fenders 
and V brakes (and, embarrassingly enough, sans brake cable cap--on the way!)


Gravel bike has a list of V-brake arm lengths:

http://www.gravelbike.com/v-brake-arm-lengths/

The Shimano Deore XT is supposed to be a nice brake, less than $60 for the 
pair and they come in at 107, one of the longer arm lengths on the list.

You probably should not count on any contemporary brakes working on your 
schwinn passage.  Canti-post placement for TINY cantilevers like the Dia 
Compe 960 is far different from canti-post placement for modern brakes.  In 
fact if you do an image search on Google for "dia compe 960" a lot of what 
you will see is photos of people trying to 'update' their brakes from dia 
compe 960 and failing.  I think those tiny cantilevers are super cute.  Use 
new salmon pads and do your best.

 The question is regarding the brakes on my Atlantis. On the front it

 Braking with the front Neo-Retro feels as if it has very little power

It will work on my Hunqapillar but I think the brake arm length is a factor

Tektro/Cane Creek and Dia Compe make road bar levers for v-brakes. There 
are no brifters that I am aware of but I have used the Dia Compe 287v with 
shimano bar ends for shifting. I don't like things like travel agents etc 
and avoid them.

I would be tempted to try Motolites if I could find long-pull reverse brake 
levers. Paul stopped making them a few years ago, and I don't know of any other 
models out there. I'd love to buy a used pair of the Paul levers if any list 
members have a set for sale. Or maybe someone can point me in the direction of 
other long-pull reverse levers? I don't want to mess around with Travel Agents 
and the like.

[Bill Lindsay]

Ian asked what is the max tire size that Paul Mini-Motos will fit.  

The answer depends on where your frame builder put the posts, but it is 
normal to run them with monster cross tires 700x45, without fenders.  With 
a fender and "good" fender clearance, maybe a 700x32.  If you don't need 
"good" fender clearance, maybe a 700x38.  YMMV depending on where your 
posts are.

[RBW] Re: Cantilever brake question...

[Brian Campbell]

This is why I no longer use cantilever brakes. V-brakes work and have 
allowed me to stop futzing. I know the purists are taught to hate V-bakes 
because they don't "look" the part, or you are lacking in mechanical skills 
if you don't enjoy spending time with them.In the real world they work 
better, are easier to set up, easier to maintain and easier to service 
(especially on the road if need be). I recently set up a set of Shimano SLR 
mid profile canti-s on a 1983 Schwinn Voyageur SP and while they work ok, I 
was reminded that they are a good bit more finicky ( and the Shimano brakes 
are pretty well designed and easy to set up as far a canti's go) and 
require more time that V-Brakes. 

I say go with the mini-motos' (if possible) and don't look back. You will 
more than likely not have think about whether or not the brakes have been 
"optimized" ever again..

FWIW, I used a set of Shimano XT V- brakes (silver) when I built up the 
Hunqapillar frame you provided me (I am keeping it BTW, figured out my fit 
issue)and the brakes were set up at the time of the build and have needed 
nothing since. More powerful that any canti brake I have ever used.

[RBW] Re: Cantilever brake question...

[René Sterental]

Here is the source of my original confusion; extracted from the article
linked by Alan:
"*Straddle cable and yoke position*
To get the most out of your canti brake, it's crucial to get the straddle
cable carrier (yoke) installed in the right position based on the type of
brakes you are running.  Simply put, you want to try to achieve a 90 degree
angle between the pivot bolt/cable anchor/straddle cable.  The angle formed
if you drew a line from the pivot bolt to the cable anchor on the arm and
along the straddle cable should be around 90 degrees.  This gives you a
good combination of modulation and power.  It's possible to alter this
angle to get more power, giving up modulation.  A rough rule of thumb is
low-profile brakes require a low straddle cable carrier position, wide
profile brakes require a high straddle cable carrier position.  Going even
lower on a low-profile brake will give you more power, but the modulation
will be lower and the brake pads will need to be set closer to the rim.
This position also will feel a little mushy at the lever.  Most lower
profile canti brakes I see have the straddle carrier set too high.  This
might feel good at the lever; solid feeling, you might say, but when you
need to hit the brakes you won't have the power needed to stop."

See the sentence that starts with "A rough rule of thumb..."

So I checked my Neo-Retro yoke position; it wasn't too high, limited by the
crown fork cable hanger, probably around 1 - 1.5" above the fender (recent
photo: https://flic.kr/p/Huku4A). Lowered it to almost touching the fender,
just 5 - 6mm away, and though the feeling increased slightly, the braking
is still less powerful than the rear Touring brake.

Next step is to remove the rack (hassle!) to install the Touring brakes and
check if the MiniMoto fit or not.

Stay tuned...

That's right Steve, and looking at your setup, the straddle seems to be

90 degrees and should gain power.

BTW, nice looking bike.

I think, to be fair, "Shimano levers" was in reference to modern STI brifters. 
Maybe not but I'd assume so given the long history of success of the brake-only 
levers and cantis from Rivendell and others.

[RBW] Re: Cantilever brake question...

[Comotion001]

I have a Calfee tandem with SPYRE disks front and rear with 2011 version 
Ultegra STI. It will stop on a dime. Of course it is a fairly light tandem. 
I've debated putting a disk on the front of my Commotion but would prefer 
not having disks on a touring bike. The bike has couplers so it comes apart 
for travel. The disk rotors can be problematic for plane travel. My 
preference for the Commotion is canti brakes. Years ago on a previous 
tandem I used the Arai drum brake which did a great job controlling your 
speed on steep decents but you can't find them anymore.

[Michael Hechmer]

I would guess that all Shimano road brake levers are designed for side pull 
brakes, cant's are not given much influence.  V Brakes were designed to 
stop mountain bikes with relatively low weight on steep descents.  Cantis 
come out of the touring tradition and assume a heavy bike at more modest 
speeds.  I suspect that Shimano levers simply pull too much cable to work 
well with cantis.  I used Ultegra STI levers very successfully with Ultegra 
brakes, but when I put them on a bike with Shimano cantis, I all but ended 
up inside the back of a pickup truck.  Probably not what OP, Rene,  wanted 
to read.  I think it would be interesting to start another thread and see 
what others experience has been.  I might post the same question on the 
tan...@hobbes.usc.edu list and see what comes up there.

 Tandems are another whole ball of ...bike.  Our loaded Bilenky tandem 
approaches 430 lbs, so stopping it is a tricky business.  Tandems do have 
one advantage when it comes to stopping.  Since the rear wheel maintains 
much better road contact than a single, the rear brake is as effective as 
the front.  Our Tandem has TRP levers, Neo -Retro brakes, and 9 speed bar 
ends.  We are not daredevils so I may not put the same demand on brakes as 
other people.

I have no hesitation letting our unloaded tandem roll downhill at 45 mph if 
I know the road and know there isn't a road & stop sign ahead.  I would not 
do that with a fully loaded tandem and not just because of a brake problem 
 A double bike, weighing 430 lbs would be pretty scary if it developed even 
a little shimmy.  And this is where overheated rims becomes a concern.  No 
rim brake will stop you if the rim overheats.  I usually alternate between 
the front and rear brakes to give the rims a chance to cool.  If I were 
coming down a long steep drop, e.g. White Face which is 3+ miles of 14%.  I 
would come to a complete stop and let the rims cool well before things got 
out of control.

If I had disk brake I would want it to be the 200mm version, but have zero 
experience with disk brakes, except on my cars, where they work great, but 
are almost as big as the wheel.

As I told my car mechanic when the brake warning light came on, " Who needs 
brakes, they just slow you down!"  Every time we head out on the tandem my 
sweetheart says, "Are the brakes on? "  To which I respond, " No honey the 
bike wont go with the brakes on."

Hey Michael, curious what brand tandem you own. I have a 2007 Commotion 
Speedster with Avid 7 V brake on front and disk on rear. I changed the read 
disk from BB7 to SPYRE. I also changed out the STI levers (terrible 
braking) with bar end shifters and TRP brake levers. That certainly 
improved the braking but still far from what I would call really good. I 
use the tandem for loaded touring and coming down mountains can be 
problematic. I've been researching better braking options but haven't come

I'm using the Shimano R600 Ultegra brake levers. My current yoke height
should he in the ballpark of the recommended height, but I'll check it when
I get home tonight.

[RBW] Re: Cantilever brake question...

[Michael Hechmer]

I have the neo retros on two singles and the tandem and have always had 
good performance from them.  If you look at Paul's setup instructions they 
do not say to put the yoke as hi as possible.  From memory they say 
something like 5".  I am not a physicist but I believe the optimal force on 
the lever comes at 90 degrees.  Obviously the angle changes as the arm 
moves upward so it is not possible to do this consistently (except with the 
Rodriguez Big Squeeze Brakes).  Therefore lower profile brakes generally 
require lower hangers than hi profile ones.

My, admittedly limited,  personal experience has been that poor braking 
performance is more likely to come from a mismatch between the lever and 
the brake as it is the cable angle and the brake.  Years ago I had SIS 
levers and Shimano low profile (550BR??) and the braking was scary.   I 
switched to Tectro levers and the braking improvement was big.  Then I 
switched to Paul's and the braking was terrific.

What levers are you using?  

I would also strongly suggest you contact Paul's directly.  I have always 
found them to be very helpful.

Spring tension? What would that have to do with how well the brakes

Well, as a general statement I am not sure, but I do know this one thing 
from personal experience: if you want to really mess up a Paul Racer 
centerpull and make it so it is completely useless as a brake, mess up 
the spring tension.  Last time I had my VO Randonneur in to have the 
brake pads changed, a ham-fisted mechanic decided to play with the 
spring tension and literally made the brake useless as a brake.  It's a 
good thing it's only a couple of miles to the bike shop... and an even 
better thing that the head mechanic had the problem fixed in just a 
minute or two.




My plan is this:
- First try lowering the yoke as low as it will go on the Neo-Retros. 
I can do it since the Nitto Campee front rack I have doesn't have the 
strut connecting it to the fork crown. Note the difference if there is 
any.
- Swap the Neo-Retros for the other set of Touring brakes, now that I 
have the low yoke. Note the difference
- Since I also have a set of MiniMotos I bought to see if they fit on 
another bike, I may try them as well, but that would mean a potential 
recabling which I'm not sure I want to do. I've also been advised that 
they may not fit well with the 50mm fenders, so perhaps I'll just see 
how they fit first, before setting them up. It was suggested that if I 
wanted the ultimate braking power, I try the Motolites, although 
they'd require a new set of V-brake levers, which I'm not so hot on.


Based on all my new learnings, I believe the Touring front and rear 
will take care of my "problem".


I'd still want to know why the wide-profile cantilever brakes have 
persisted for so long...



Here's some of what Paul says about the Neo retro:
/Note: These are very powerful brakes and have a tendency to overpower 
thin tubed frames (in any material). For none-too-stout frames and 
forks we recommend our //Touring Canti 
//. Also, 
the arms stick out a lot! For smaller frames, bikes with bags, and 
people with large feet there can be some interference problems, in 
which case the Touring Canti might be more appropriate./


Clearly they are of the opinion that the Neo retro is the more powerful 
of the two, and honestly after all this time you'd think they'd know 
their own products.

Re: [RBW] Re: Cantilever brake question...

[René Sterental]

Spring tension? What would that have to do with how well the brakes stop
the bike? Besides, spring tension is the same between the front and rear
brakes.

My plan is this:
- First try lowering the yoke as low as it will go on the Neo-Retros. I can
do it since the Nitto Campee front rack I have doesn't have the strut
connecting it to the fork crown. Note the difference if there is any.
- Swap the Neo-Retros for the other set of Touring brakes, now that I have
the low yoke. Note the difference
- Since I also have a set of MiniMotos I bought to see if they fit on
another bike, I may try them as well, but that would mean a potential
recabling which I'm not sure I want to do. I've also been advised that they
may not fit well with the 50mm fenders, so perhaps I'll just see how they
fit first, before setting them up. It was suggested that if I wanted the
ultimate braking power, I try the Motolites, although they'd require a new
set of V-brake levers, which I'm not so hot on.

Based on all my new learnings, I believe the Touring front and rear will
take care of my "problem".

I'd still want to know why the wide-profile cantilever brakes have
persisted for so long...

I'd read the black mountain cycles article on the topic.  Also I believe I read 
on the Paul site that for neo retros 2-3" yoke height is good enough.  I didn't 
read thru all the posts but have you adjusted spring tension yet?

Low profile cantis are generally as a rule stronger brakes (more mechanical 
advantage) than high profile. Not sure why Paul states otherwise. Getting low 
profile brakes set up correctly (lots of squish) was a revelation, they inspire 
a lot more confidence on my MTB

I've had REALLY good experiences with the cheapest Shimano cantilevers you can 
buy - the Altus can be had for about $8 a set (cheaper than most pads even). 
They are easy to set up, quiet, powerful, look good, and feel nice at the 
lever. Give them a shot!

[RBW] Re: Cantilever brake question...

[René Sterental]

Jay,

Thanks to that article you linked to, I finally got it. Now I understand
it.

Still some practical questions:
- Why is the typical setup Neo-Retros in the front with their lower
mechanical advantage that requires so much more force to be applied?
Because they're less finicky to adjust and have more clearance? If the
front wheel does the most actual braking, why would you place a low
mechanical advantage brake there?

What I read, and hopefully understood correctly, is that the preferred
setup was with wide profile cantilevers like the Neo-Retro both front and
rear, but due to the prominent brake being a nuisance with bags, panniers
or other stuff, the low profile cantilevers were used in the rear instead.
In fact, a friend just bought a Soma Randonneur and it came with low
profile cantis front and rear. But isn't the low profile canti a better
more effective brake? Or at least it would seem that the medium profile
is... So why are those not available?

I now understand the how to set them up, but not quite yet the why...

Bill? You seem to understand this better

René, who wants to know more and has always asked why?

[René Sterental]

I'll have to go and re-read everything, can't figure out how I could have
understood it in reverse.

No matter what, it seems the Touring are going in the front when I get home
this weekend.

But I still want to understand it.

[RBW] Re: Cantilever brake question...

[Jay Lonner]

My cantilever education is ongoing. I must have read Sheldon's guides a 
dozen times over the years, but when it comes to actually getting the 
brakes to work it's like being back in school where I do the reading but 
blank on the test.

Anyway, I've had Neo-Retros on my Hunq since I got it, and have never been 
happy with the braking. On my most recent dive into cantilever theory and 
practice (informed this time 
by http://www.circleacycles.com/cantilevers/canti-geometry.pdf) I 
determined that wide profile cantis like this do best with a low cable 
yoke. That wasn't very feasible for my setup, because of interference from 
racks and fenders, so I ended up replacing the Neo-Retros with Paul Touring 
cantis, and so far the braking is much improved, although squealier. So I 
endorse your plan of replacing the Neo-Retros with a set of the Touring 
cantis. FWIW, the mid-profile Shimano cantis that Riv sells and endorses 
seem to be widely admired, and they will be my next step if the Touring 
cantis disappoint me once the wet weather returns.

Incidentally, I have a set (i.e. one bike's worth) of Paul Neo-Retros for 
sale! Inquiries welcome.

[Bill Lindsay]

"Per my education, the Neo-Retro needs the cable yoke to be as high as 
possible"

You were educated incorrectly, or made the wrong conclusion from your 
education.  The Mechanical Advantage (MA) of wide profile cantilever brakes 
like the Paul Neo-Retro is mathematically pretty FLAT as a function of yoke 
height.  It doesn't matter much how high you make the yoke with wide 
profile cantilevers.  Your description of not having enough power, and not 
being able to stop the bike with the front brake means you have TOO LITTLE 
Mechanical Advantage.  Even though the MA of your front brake is 
comparatively flat, the higher the yoke is, the less MA you have.  If you 
want to see how much more Mechanical Advantage is available to you, lower 
the yoke height as low as you feel comfortable lowering it. 
 Mathematically, it won't make a huge of difference, but it will be more 
Mechanical Advantage, and that might feel great to you.  If you try it with 
the yoke low, and still don't feel like you have enough power, then a 
narrower profile brake like the Touring Cantilever, has far more range of 
MA vs yoke height.
