    Shimano series 600 components

    I have an older Cannondale with the Shimano 600 series (grey) parts. Was thinking about using the parts in building up a new steel frame. Is there that much difference between newer Ultegra and the older 600 parts? Beyond the fact that the older parts have had some use? The Cdale is 7 speed, what would I need to change with the original components to make the new frame into a 9 speed ride?

    The grey-painted 600 parts came from the late 80's and early 90's, and are good-quality stuff. You probably have late-80's, since the parts are 7-speed. I'm guessing you have downtube shifters, too? And single-pivot brakes? (Below is a picture of 600 dual-pivot brakes from an early-90's 8-speed group.)

    If you want to switch from 7-speed to more speeds, you'll need to replace the freehub body (the part on the rear wheel that holds the cassette sprockets) and the shifters. Modern shimano-compatible freehub bodies hold 8, 9 or 10-speed sprockets (but not Dura-Ace 10-speed sprockets which have deeper splines). So if you replace the freehub body you could just update to Ultegra or 105 10-speed STI shifters, or older Shimano 9-speed STI shifters.

    The crank and deraillers and brakes in the 600 group were very good, back then as well as now.

    timcupery, thanks for the help and feedback!

    I do have the DT shifters but I believe the calipers are dual pivot and I'll check when I go home tonight. So to go to the 9 spd, I'd have to replace the freehub and the cassette? Does that mean I'd have to replace the rear wheel or rebuild it around the new hub? The wheels are Campagnolo and I'd hoped to use them but maybe they'll need to be replaced?

    Before starting the conversion to 9-speed, you need to be sure that you have the needed dropout spacing. Standard 7-speed spacing was 126mm. That was expanded to 130mm when 8-speed arrived, and has stayed there through 9- and 10-speed. With a steel frame, it's no big deal to spread the dropouts by 4mm, but if your Cannondale is aluminum, that's a serious problem. It might preclude the upgrade altogether.

    GCRyder, actually I am planning on using the 600 series parts on a newer steel frame that already has 130 mm spacing. Thanks.

    well, I missed that completely, though I see it now. At least the otherwise useless post earned me an upgrade from "Newbie."

    You're welcome.
    How is it that you have Campagnolo wheels (do you mean hubs, or the whole wheelset?) with a Shimano 600 7-speed group? Campy hubs are a different story if you're upgrading the freehub from a 7-speed to 8/9/10-speed. Give some more details on this - what are your hubs? what cassette is currently on there? Etc.
    If you have a Shimano or shimano-compatible hub, then it's easy to just get an 8/9-speed freehub body. You'll need to redish the wheel to move the rim over 2mm to the drive-side.

    Timcupery,

    I checked my Cdale last night and it has Campy wheels/rims and Shimano 600 hubs. The crank as well as all the other components are Shimano 600. The crank is a 53/42 x 170. The cassette, couldn't really find anything to identify it by? Are the Shimano hubs good quality for todays riding as I am wondering if I should replace the hubs and update the rims? I like the older wheels but I want to make sure the wheels can keep up with the bike.

    Okay, that makes sense. You don't have "Campy wheels" but just Campy rims. If you had Campy rims and hubs, then you'd have Campy wheels.
    I was wondering how your bike shifted if you had Campy rear hub because it wouldn't take a Shimano cassette. So you probably have a Shimano (or Shimano-compatible) 7-speed cassette.
    If the rims and hubs are in good shape, keep them. Campy makes good rims and Shimano makes good hubs. You'll need to get a new freehub body (Nashbar has them #1 #2 and you can get them at pretty much any bike shop). You'll need to respace and redish the rear wheel to 130mm spacing but since it's a Shimano hub it'll take an 8/9-speed Shimano freehub body (which will also take 10-speed cassette that's not Dura-Ace). Sounds like all your parts are good stuff.
