I've done this, but there's no need anymore: https://store.velo-orange.com/index.p...ch-brakes.html

Also, with the DIY method, there's a set screw to help keep the bolt from rotating that mars the threads. When you remove the bolt from the caliper arms, it buggers the soft aluminum threads on them. My set works fine, but I wouldn't be able to disassemble and assemble them again.

I think the issue is simply that modern dual pivot systems require less applied force to achieve similar stopping power. My girlie-man hands prefer them too.

You just gave the SP-ers a reason to make fun of us.

mazdaspeed

This is true but also misses the point that with the same applied force to the lever the stopping power is always greater. It's not like you can pull on levers harder just because they have single pivot brakes attached to them.

mazdaspeed

lol... if they want to ream on their brakes every time they want to slow down that's fine.

Puget Pounder

1 thing I don't ream.

So, how'd this turn into a debate when clearly it was asked about setting up DP's without drilling and if anyone can show pics?

shorthanded

this man is smart, and posits a good argument, but ultimately-- if something can 'do the same thing as DP's'-- i'm lost as to how it is 'better'. that's the entire basis of 'it's an unnecessary invention'. i didn't infer it was a BAD invention, or that they don't work (although i've used several pairs thar really didn't..)-- just that they FEEL crappy. i got no beef with technology that works fine. i just think DPs often feel like crap.

ultimately, who cares if DPs are 'better' if they feel crappy and make a bike feel cheap? I ride what I like, as do you. i'm clearly not dead from careening into traffic, nor are you. my argument is based on feel, and again-- most DPs, save for the shimanos as noted, feel squarshy to me. that's not curmudgeonish (a'la MS)-- that's a clear preference for one type of lever action.

the other day a cute jack russell decided to cross a bike path with me on it, going at full clip in the drops. I stopped a hair's breadth away of the poor dog, I think I wouldn't have been so lucky on my sidepulls, but the excellent Campy dual pivots made sure nobody was hurt.

Wrong!

I'm not sorry for saying this. A Tektro dual pivot caliper with the OEM pads properly set up is functionally superior (by far) than any single pivot caliper of the same reach with any pads. If you're denying this you are lying to yourself and spreading falsities on the internet. Shame on you.

If, for whatever reason, you prefer single pivot brakes, that's A-OK. I use them and like them. But, dual pivot calipers are an improved design. That's not debatable.

Here are the Tektro 800 calipers on my daughter's Sports:

Excellent!!! Thank you John! Those still look quite classic on that bike. Great solution for female frames where the rear caliper has the barrel adjuster and binder reversed.

Puget Pounder

They're better because of their design--how the torque arms are closer to their pivot point. That's where the improvement is. So they do the same thing, but with less effort. Also because of the added modulation and the ability to do an isolated adjustment of one arm. I don't judge anyone for riding single pivots because I do too. I'm just arguing that they are better on paper as well as to a majority of people who use them.

I apologize, I'm not trying to be rude. Your experience says that DPs are crappy and you actually said in an earlier post that DPs are actually weaker. I just have a tendency to debate.

Sorry to the OP if this argument hijacked the thread.

No shiite, it has convinced me that it is probably not a big deal to actually "drew" the front fork to get the recessed nut DP's to work.

For my 2 cents. The dia-compe G's that i'm replacing were dialed in to pretty much stop on a dime but there is a noticeable difference compared to the shimano 105 DP's on my CF bike. Plus I like the look better of the modern DP's, and the black finish on the ones I ordered is going to make my bike so sexxy it hurts.

Not at all, I got my answer about halfway through the first page. It wasn't what I expected but i've been enjoying the fairly reasoned debate that has ensued since.

Those brakes look like they were made for the Raleigh Sports.

thook

It's not, really. But, I do wish I'd known there were nutted style before I drilled. I'm definitely not gonna drill the bridge, though. I'm going to flip the brakes from front to back as suggested. Sheldon's suggestion about the fitting a rear recessed on the front was/is interesting: Install the backing nut and washers up inside the steer tube. I may try that if I can't get my hands on a really long recessed nut. In which case, I figure I can still mount a fender behind the crown with another very short bolt and nut........thereby hiding my drilling job.....

I have Tektro R559 purchased here: https://www.sheldonbrown.com/harris/b...ers.html#55-73
on a mid '80s Schwinn World Tourist. Incredibly powerful, easy to modulate brakes. They are opposite hand to the original side pulls, which caused no issue on the front. On the rear, I mounted it in front of the seat stays, which made mounting the rack a lot easier. I am running 27" (ISO 630) wheels, and the R559 has plenty of reach to switch to 700c (ISO 622) in the future. No recessed nuts, no bike modifications.

thook

Got any pics of that Tourist set up???

shorthanded

come on, lloyd. firsly-- scolding? really? secondly- YES- i PREFER them. I only stated 'THEY FEEL CRAPPY TO ME' at least 4 times.

curious how some members of this forum seems to have a reading comprehension problem, not to mention a foreshortened sense of humor. if reread what i've said, i seem to've NOWHERE said DPs don't work. in fact, i praised them several times for their shimano iterations. no arguments of physics, no claims of technological failings. just that they don't feel good. and the tektros i had with oem pads blew. badly.

should the internet wish to contact me to send it's shame my way for being the ONLY person spreading falsehoods, i'll gladly give it the bird. that is also undebatable. if the mods would like to ban me for my 'transgressions', by all means.. but boy you gents'll brew a tempest in a lukewarm teacup.

now i see why folks like rich cranium hassle you guys...

Puget Pounder

Hope you're not making fun of my reading skills. You said that single pivots have twice the spring power. Sorry if I said anything that made it personal. I just like a good ol' fashioned debate.

michael k

Dang,I swear this site is on daylight savings time.

one more picture.There was not enough meat on the rear bridge for recess nut so a front caliper was used with washers from a center pull.




Thanks again JohnD for the hookup on the wrong-sided calipers.

noglider 

What kind of rack is that, michael k?

ColonelJLloyd 

My post was humorous. I think you're on the defensive so you didn't see it that way. I don't have reading comprehension issues. Nor do I have spelling, punctuation, capitalization or sentence structure issues. You've demonstrated all four in one post.

As my post plainly stated, if you prefer single pivots that's great.

realestvin7

So what DP offerings are there in 60mm reach?

michael k

Not sure.picked it up at a co-op. There was one on ebay some time ago with lights mounted to it.
