    Front derailleur for 1989 cannondale?

    Hey all, I'm fairly new to cycling world, I have a 1989 black lightning frame and I was planning on using a clamp style front derailleur but it doesn't fit. So I'm assuming I need a mounted style fd? I tried searching the Web but couldn't come up with an anewers just some aweosme pictures. can someone point me in the right direction?

    I have shimano golden arrow rd, fd , and shifters I wanted to use. I'm thinking of posting them up in the trade thread for the parts I need for this build. Thoughts? I really appricate any help or advice that can be given.

    Thanks!

    Your bike probably uses a Braze on Derailuer. the bracket for the Braze on may or may not be there. If its missing then you should have 2 bolt holes in the tubing right by where the derailuer would mount.

    Golden Arrow stuff is like a generation earlier (and two levels lower) than what would have gone on the Black Lightning. IIRC, that was all Suntour Superbe.

    Yeah the bracket is missing, I see the 2 bolt holes. So what do I need to do?

    You need to find the missing piece: eBay, co-op, whatever. Looks like OJ found you just what you need (below).

    Front derailleurs are made in different styles (braze-on and clamp-on).

    Sounds like your bike may have had a braze-on front derailleur bracket on the frame, and for some reason the braze-on bracket was removed. You can by a replacement braze-on bracket and have it installed, OR you can use a clamp-on front derailleur adapter, or a clamp-on front derailleur.

    Manufacturers use some standardized diameters for the tubing used to build bicycles, and derailleur manufacturers make clamp-on front derailleurs with different diameter clamps (some common sizes are: 26.6mm, 31.8, and 34.8mm diameter clamps) to fit the various sizes of tubing. You can also buy clamp-on adapters which are designed to be used with braze-on type front derailleurs. Some bicycle manufacturers built their bicycles with clamp-on adapters and supply braze-on for derailleurs to match.

    Standardized Clamp-on adapters for braze-on front derailleurs are made to work with round set tubes. If the seat tube on the bike is not round, you would be forced to replace the bik manufacturers braze-on bracket, or maybe the bike manufacturer has a specially made clamp-on adapter for the bike.

    My 1989 Schwinn 754 aluminum bike has a clamp-on adapter, as do my 1990s Trek road bikes, and the 1988 Trek 1000 that I bought and restored for one of my sons.

    Measure the diameter of the seat tube, buy the appropriate size clamp-on front derailleur adapter, then buy the front derailleur of your choice in the braze-on style.

    If your heart is set on using the Golden Arrow front derailleur that you have (that doesn't fit), and the front derailleur is not a braze-on type with a clamp-on derailleur adapter, you are going to have to look for a braze-on Golden Arrow front derailleur, and a clamp-on adapter the right size to fit the seat tube of your bike, OR look for a clamp-on style Golden Arrow front derailleur with the right diameter clamp attached, .

    ^Best answer^

    I'm guessing your seat tube diameter is 31.8, but that's just a guess. Once you've determined that, there are gadzillions of good used front derailleurs on the big auction site (or at your local bike co-op) with that size clamp. Easiest and cheapest way to go, once you're sure of the seat tube diameter.

    Will the holes for the missing mount (linked in oddjob2's post) interfere with the attachment of the clamp-on derailleur? My Cannondales use clamps so not sure exactly where the mount holes are or if they would be an issue. It seems they might be at least close to where the clamp would go.

    I can say from very recent experience; yes, the rivnuts for the braze on mount WILL interfere with the clamp on FD's.

    Yes, best way to do this right is to source a new FD bracket. There is a company that makes them now, use the Googly to find it, they cost around $18 each. If you can't bring yourself to do it right, use a 31.8 clamp (either a stand alone clamp or a clamping FD) and file away to create clearance where it hits the riv nuts so you don't collapse the seat tube.

    But my advise is...do it right.

    Alright, so I ordered the mount a while back. It had some shipping delays for some reason, but I got it in the mail today! Now, does anyone know which way to install this thing?

    Google gold plated derailleurs.

    If I had a Black Lightning, I'd do all the clamps and metal components in gold leaf. You can get the sheets for cheap. I'd have a pro do it for me, I might have to fake a 27" Black Lightning now out of an ST just to do this. My goodness would that look good with vintage Campy components.

    That would be cool, I'll definitely look into it. If not gold defiantly black. Right now I'm just trying to get it on the road though, then upgrade as I can
