I look back on the last 15 years of my cycling life, and I gotta say.
Cantis suck. Single pivot sidepulls suck. The disc brakes on my weirdo project
bike brake very well, but go

Doug, you pose the perfect question for me to share my experience with
cantilevers and why I continue to believe in hi straddle and hi profile
cantis.
My first experience with cantis, after years of good riding with Campy Grand
Sport LR brakes and Chorus SR brakes came around 2000, when I

Aha. My rule-of-remembering has been high profile = high hanger; low
profile = low hanger, just like Michael's, until I put this brake on
with every mm eked out of the straddle wire and it was still
disappointing. I'll try a long longer straddle wire, and possibly a
wider hanger first. And those
Sheldon (RIP) did a great job of laying out the geometry factors, but didn't
really get to the punchline.
The punchline, in my opinion is that the mechanical advantage of high
profile cantilevers is almost constant regardless of straddle cable length.
Brakes like Tektro CR720s and old
Thanks for that explanation, William,
that was enlightening, and jives with my experience. The way my non-
engineer's brain makes sense of this is this:
The main brake cable moves up when you engage the brake. For a high
profile canti to engage you also mostly need to pull up on the
straddle
I'm using Kool Stop Mountain in the front and the Thinline in the
back. I do not like the Thinline with this brake.
I found that I had to RAISE the yoke in the front. I guess different
levers can have a big impact on mechanical advantage even thought they
are all made for cantis?

Agreed, it is a very nice-looking hanger, and most importantly for me,
it uses a 10mm box wrench and a 5mm? Allen key to adjust. How many of

They are the best looking I have ever seen and are completely self

My experience with the CR720 requires the yoke to be as high... so
high that I had to use an extra-wide yoke because the straddle cable
wasn't long enough.

I don't own these, but have considered buying a pair of the Tektro brakes
for a winter bike. The Riv photo, with the barkes installed doesn't show
the additional screw. But more importantly how do you like the brakes?
Stopping power? Ease of set up?

Super easy to set up and very strong. I have them on all my bikes.
Gotta replace the pads though.

Agree with rcnute, these CR720 is easy to setup and quite powerful
especially with salmon pads and the straddle cable as low as possible.

Another plus is that (for me anyway) they seem to work well with non-
aero levers--sometimes it's hard to make those levers work with
cantis. I have some nice Campy and Mafac levers I wanted to use.

My take: I think these are indeed the best straddle hangers out
there. Here's why. You position the hanger for optimum/even pull
from both brake calipers, then you set the screws and secure the
straddle wire so the hanger remains perfectly positioned; without it
the hanger can float and
The argument that the Tektro hanger is the best...is a funny argument
at some level, because any decent one from the pas 70 years is 98

opinion--the final 2 unimportant percent, because if for any reason
