will 6500 series ultegra brakes fit on most early 80's C&V?
(700c w. 25mm tires in a 27" fork- miyata sidepull stock)

Will they work with non-aero levers- dia compes?

stopping power of today with yesterday looks? do able? (like replacing drum brakes with disc on a car)

anyone else that did this?

I tried 6400 series brakes with some slotted Superbe non-aero levers.

The 6400 brakes have that SLR feature- the brakes don't really have a return spring to pull the cable back- the levers have a spring in them to return them to the "ready" position.

If you use "old fashioned" levers, you have to manually "help" the lever back to the "ready" position.

If you're looking for non-aero levers and more modern-y Shimano brakes- I know there's options in the Dura Ace 7400 and Ultegra 600 6400 series levers.

Check out on eBay- they pop up from time to time- When I got my 6400 aero levers, I had the choice between the non-aero and aero- In the absence of the slotted levers, I wanted to be all cool and modern with aero levers.

WOW! I didn't know about these, So I could mix a 6400 non-aero lever with a 6500 dual pivot brake and have the levers return without helping them?

just an update to add to the knowledge base.

Just hooked up a ultegra rear-

Yes you can mix old 27" frames running 700c X 25mm tires with ultegra 6500 series brakes and non aero dia compe levers and have tons of clearance.

Braking power its better than stock dia compes but probably even better with matched shimano levers. (on order)

IF adjusted properly you do not have to assist the levers back up- that's only if you are sloppy with setting them far away from the rim.

BUT the issue is that the back will only fit if you use a front brake- the bolt is very short. on the front with the front brake the bolt is too short for early 80's forks.
the problem is that the bolt is threaded 2 ways- it get bigger near the head.

Shimano SLR brakes most certainly have a spring! I have an old road bike set up with a flat bar. The brakes are old single-pivot Ultegra SLR with cheap Tektro MTB-style levers with no return spring. Works great. I can't imagine standard road levers without a return spring would work any differently.

I had the problem with the levers not returning- started a thread, and the general consensus was that the SLR brakes were meant to work as a unit- the lighter spring tension made for easier action braking, and the return spring in the levers pulled the levers back to the ready position.

I may have set them up incorrectly, however after removing the Superbe levers and putting on 600 TriColor levers- the system works fantastically.

my miyata needs longer front bolt so I have dropped off a bolt to a machine shop to get manufactured- think its just miyata wackiness as my apollo looks like it would fit it.


Why did shimano make that bizarre 10.5mm nut that you need vice grips to strip and remove it? do they have a proprietary tool or am I that tool?

dddd

Shimano, for good reasons, doesn't want the brakes being taken apart at the home or local-shop level.

The Dia Compe 202's look really nice, non-aero with slightly wider hood. There is also a drilled version, but they're quite pricey (can be found cheaper if you shop around).

I'm curious about this "it get(s) bigger near the head problem (I assume you are using the recessed nuts). Usually the knurled nut on the back covers the slightly larger thread. If not you can always place a washer to space the knurled nut a little farther..(velobase.com)

no its a hundred dollar bolt custom made 2 centimeters longer.
