Putting Dura Ace 9000 Caliper Brakes on old 80's Frame.

Hey All, Just a quick question: If I wanted to replace the Single Pivot Shimano 600 brakes (BR-6208 I think?) on my 80's frame with Dura Ace 9000 brakes, Would it be a good fit? Theyre Both 39mm - 49mm reach, but I wasnt sure if I there might be a problem in doing so.

I have these exact brakes: http://velobase.com/ViewComponent.as...E-D573C762713A

Thanks!

I think the very recent Shimano dual-pivot brakes have a bit different cable-pull than before. If that is true (others can confirm or disconfirm) I'd recommend going with a bit less-recent dual-pivot brakes, unless you want to change up your brake levers as well. The bit-less-recent brakes will have the added benefit of being available more cheaply. If you already have a set of Dura-Ace 9000 brakes sitting around, you're probably fine to go ahead and use them. But wait until someone who nows about the cable-pull responds to this thread.

Oh Funny enough... I was prepared to change up my levers too. I have some Shimano 600 Levers on my bike now, but i Bought a pair of TRP RPL Brake Levers to go with my new set of brakes.

These are the levers, if that helps anyone: http://www.amazon.com/TRP-RRL-Brake-.../dp/B005J5BV40

The new brakes mount differently. You'll need to drill out the back of the fork (which is simple) and the back of the brake bridge (a bit more difficult as a drill will not fit - I use a stepped drill bit in a pair of vicegrips) to accept the new style of nut.

You're covered if you're already getting those levers. Which will be much more comfortable than the Shimano 600 levers of the early-mid 1980s.

The new brakes should mount the same as the old ones. Bikes that came with that level of componentry typically had frames that used allen bolts to mount the brakes (which are the same as modern brakes, like the Dura-Ace 9000, use). I have a Centurion Comp TA from 1984 that came with those same Shimano 600 brakes that you have. So in all likelihood, no frame modification will be necessary.

Cheaper 1980s frames (and most frames from 1970s and prior) used longer bolts from the caliper brakes, that tightened down with a nut, whereas recessed allen-bolt fastenings require a larger hole in the frame.

Largely its about reach , how far the mounting hole is from the rim where the pads have to grip..

Appreciate it guys, It sounds like I wont have a problem with the installation and both the shimano 600 brakes and dura ace brakes are short reach (39mm - 49mm).

If you've confirmed the reach is the same and the 600 brakes have the recessed mounting you're good to go.

What else are you putting on to live up to the DA9000 brakes?? I'd like to hear the rest of the build.

Hah, Well Not much else at the moment, I had the old ultegra single caliper brakes since I bought the bike from someone 2 years ago. Those brakes are no longer cutting it as I have to start braking maybe 30-40 yards before I can come to a full stop. So I'd figure I am due for an upgrade, so why not the BR-9000's? Either my Brakes were super worn or I've become a more powerful cyclist lol.

Eventually though I would love to do a full groupo upgrade, though I am not sure if this is even possible. For now i am just sticking with the brakes.
