1984 Miyata 912 ; front fork replacement

You can start looking on eBay and call your LBS. My LBS has a good idea of who in the area is selling a bike with parts that would fit one of my vintage bikes when I am in need of a part. Yours might also.

It has been several years and I don't remember who it was, but there was a conversion kit out there that allowed you to replace your fork that had a 1" threaded steerer tube with a fork that has a 1-1/8" non-threaded steerer tube. Of course you had to get a stem and often, shims for your old handlebar, but it made the bike rideable. Your LBS might have a line on this kit also.

Good luck in your search. Miyata was always one of my favorite manufacturers and I always liked Maeda Suntour components when they were around. I have a vintage Lotus that I was able to build up with a NOS Suntour Radius Group set, except for the hubs which are Suntour Cyclones.

Kdelond, thanks for your reply; I'll try your suggestions. Sounds like a nice Lotus.

There is a local frame shop here in Dallas that I might try; it is steel, but that might be too much/ too weak of a bend for Chromoly. It almost appears that if you could separate the soldered steerer from the crown, you could fabricate a new steerer. Don't want to spend a lot of money on it; but, don't want to part it out either.

The bike size is 54cm and the steerer is 1 1/8 OD threaded.
