good deals on headsets?

My 1989 schwinn prelude needs a headset but i'm not sure what kind it needs, and where I should get it. I don't care if it is vintage or not. I was also wondering what the specs for the bottom bracket are, since it also needs one of those and I might just go to a sealed bearing one.

tange passage for the headset.

it sounds like you might need help from your LBS. they should be able to get you the right BB to match your crank and install your headset.

I don't need help installing anything. I just don't know if the headset is iso or jis threaded. I think the bb is English threaded but I just wanted to be sure before I ordered the parts, especially since I'm going to use a newer bb and possibly go to octalink.

Tange Passage is a good headset for the price, and will match up with the other stuff on the bike.
If you plan to race it or really hammer around, double your investment with a Tange Levin, maybe.

Doubt it will be JIS

you probably want to take the old stuff out first to make sure you order the right parts.

The bike will be raced. Tange levin sounds good. As for taking everything off first, that's an odd thing to say. The headset didn't have anything useful marked on it. The bb might have the thread pitch marked but I mostly just wanted to confirm that it was English.

Maybe I should take this to the racing sub forum?

You want to measure and see if it's JIS or ISO. The '88 Schwinn Circuit had a JIS Tange Falcon FL-500 so the odds are good that yours could be the same.

Yeah, I was reading up and found out that I can measure it. I thought they might have just had a different thread pitch or something. I will find out once the frame and fork get back from the powder coaters.

+1 on the Tange Levin HS. I've put them on a couple bikes and for around $20 they can't be beat. For some reason they seem to install and adjust especially easily.

+5 on the Tange. Awesome quality, lasts forever, and inexpensive. eBay is an excellent source, or try Loose Screws or Niagara.

This is a Tange headset.

Can someone help me understand that sizing? Is that a French thread?

Thanks.

Actually, if I'm reading the box correctly, it only tells you about the diameter and threading on the threaded race and locknut. 25.4 mm (1") x 24 TPI. It can be ISO, Italian or JIS, but not French.

Hmm. Thanks. You could be right.

Oddly, I'm pretty certain this was purchased TO BE French. I think I bought this in/about 1979. It's come out of a deeply buried parts box, so I have only the most vague of memory (!!) regarding this.

But, re-reading that, you could be right.

Sigh. Oh, well. Wonder who the hell would need this?
