Classic Cannondale SR500, 1987
Looking for help in re-componeting a classic. I know I am limited to a six in the rear, but need to get rid of the Biopace front crank. Additionally, I would like to change out my brake set....any thoughts in staying with Shimano line??
Cannondale offered no help whatsoever!
Thanks,
Cheers.

I'd go with Shimano 600 (pre-Ultegra) on the rear derailleur, a set of downtube indexed shifters, era front derailleur (you could go matching 600) for drivetrain. Good choice on tossing bio-pace. I have an '88 Criterium Series with 600 RD with a modern light racing wheelset and 12-28 7sp cassette. Nothing shifts smoother or more reliably. I built this from a frameset 3 years ago and it has never missed a shift. This is my favorite roadbike and is a rocket.

You need to search the "Show us your vintage Cannondale!" thread on this forum. You'll find lots of ideas and mods.

With the right hub, you can go 7 at the rear. Even 8 if you go friction although it's hard to find the right parts.

The chainrings are Biopace, not the crank. Don't know why you have to switch it out unless you can't handle a 42, but just replacing the chainrings is an option.

I'll echo @clubman. My winter rider is an '88 ST400 and I'm running an 8 speed HG cassette set up with the first generation of Shimano barend shifters in friction. I barely have to spread the rear to mount the wheel.
If you are just looking for functional calipers at an affordable price, check out Nashbar's house brand. I run these on my '93 R600. Work great and not expensive at $40. IIRC I picked mine up for under $30 on one of their sales.

Still learning
Agree with oldscool, 600EX is great value.
My preference would be TriColor/Ultegra or the widely available 105 if on a budget.
New calipers? Tektros are the cat's pajamas for functionality. Not much more than 2 pair of Koolstop pads.

On my 1985 SR300 a 130 OLD hub goes right in there with minimal effort. So basically you can run as many speeds as you want. Mine has 8 speed Shimano stuff on it. At one time I had it built up for my wife with 10 speed Shimano STI stuff.
As mentioned, you can probably just swap out the chainrings. Most Shimano road cranksets from that era will be 130 BCD so the sky is the limit on chainrings. Nashbar has the Race Face 39/53 sets on sale every now and then. I know I stuck a half dozen on my shelf for well under ten bucks a set. I actually like Shimano Biopace and the SR Ovaltech rings.
Any 39-49 reach road caliper with recessed mounting hardware will work.
