I forgot to say, but since you brought it up, I have a nice pair of Modolo single-pivot sidepulls. Obviously, they want to go on one of the Italian bikes, but I need to improvise a cable stop for one. They're in really nice condition otherwise, especially for their age (I'm guessing 70s or 80s).

I used Shimano 105 single pivot upgraded to Shimano 105 dp, then upgraded to Campagnolo Centaur dp brakes on my bike. At the end I 'downgraded' to Campagnolo Chorus monoplanar brakes.
I prefer the Chorus with modern brakepads and cables.

I'm not convinced it's actually an upgrade. I've broken traction with canti's, V, center, side, and coaster brakes. I've descended actual mountains (multiple miles of 9%) on loaded touring bikes with side pulls and cantilevers and both worked just fine. Heat rejection seems to be a big player there, really.
Have ridden in quick (20-25mph) groups and lines with V, canti, and sidepull and maybe some others as well - the modulation was fine.

I've occasionally said that you don't really know a bike until you recognize it when riding it in the dark, and I'd be surprised if 5 degrees farenheit didn't make more difference than swapping a decent sidepull for a similar level dual pivot with similar pads.

In the grand scheme of things, unless you need real wet weather stopping or are carrying a heavy load and worry about exploding a tire, go with what you think is pretty. They all can work really well when you aren't looking at them.

Right now, I'm liking the look of centerpulls. I appreciate the symmetry. Side & dp are fine, and I have a medium reach pair of 600's I fully intend to use, but not right now, thanks.

howard's onto something. i think choice in lever is more important to the feel of the braking than the single/dual choice. and pad choice is maybe even more important.

a modern lever, combined with the best pad available, functions nearly as well with single pivot side-pulls as with duals. i will say, though, setup and maintenance are easier with dual pivots.

It looks pretty cool. And "rebellious."

Dual pivots are SUPER easy to set up, and that's probably the main reason I prefer them. I have plenty of experience with them and with centerpulls, and less experience with single pivots. When I have used single pivots, I found that with good pads they stop you just fine--however they are annoying to set up properly (for me, anyway). Given the choice, unless there is a reason I need to be "period correct," I will get some Tektro dual pivots with Kool Stop pads on there and be done with it.

Am I missing something? I always thought single-pivots were super-easy to set up too, as long as you have the 13 or 14mm cone wrench...
Or was I just a spoiled kid with my Dura Ace while all the kids at the orphanage were diddling with their inferior Campy brakes?

Oh good, another DP vs SP thread.

I dunno, maybe you're just super talented! I haven't used Campagnolo or Dura Ace single pivots, only midrange ones from Dia Compe, Weinmann, and Shimano. They all were pretty annoying to set up and get centered, cone wrench or no. I'm sure it gets easier with practice, like everything--but I have no real reason to practice.

Rebellious?

SOP for a lot of us. Campagnolo has been selling brake sets that consist of a dp front and single rear for quite some time.

I have gotten in the habit of taking pictures of stuff before I take it apart so that I can be certain I get it right.

It almost sounds like you're putting yours back together when you're done. (?) Actually, I was surprised at just how easy this was. Looking at them, I expected way more parts hiding inside.

But that's just not as cools as a first gen Dura Ace caliper in the rear and a nutted tektro on the front, completing the ultimate in frankenbikes haha.
