Wanted: Schwinn fork, mid '70's "lightweight"
 

Need an old schwinn fork for a steerer tube splice on a mid '70's Sport Tourer. Condition of the fork blades and crown are immaterial. Cannot be threaded for half the length, like the service replacements seem to have been. That's what caused the cracking issues on the current fork. Longer the better, this fork is for a 25" frame. If you just happen to have a looonnnnggg fork for an Opaque Green "lightweight", that would be just bananas.

There is no difference in outer diameter and threading between a Sports Tourer fork and a regular 1" ISO threaded fork. The difference is in the inner diameter. So if you are ok splicing a regular 1" threaded steerer from any framebuilder supply shop onto the fork, and using a regular 22.2 quill stem, you should be good to go.

If you go that route, you might need to sand down the inner diameter of the top lip of the current headset lockring a little, to give more clearance for a 22.2 stem. Besides that the current headset should work fine with an ISO fork.

Yep. I am aware. However, I'd prefer to use the original stem from the Sports Tourer, so Schwinn steerer tube is the preferred solution.
All else fails, I'll splice in a "normal" steerer tube.
Planning on checking at the coop on Thursday.
Otherwise, it looks like a random Ebay purchase may the ticket.

nesteel you might try Bicycle Heaven in Pittsburgh,he has all kinds of Schwinn forks on display and he sells them. 412 734 4034 Craig Morrow is the owner
