Schwinn Premis fork question
Hey gang. I was referred by the folks in mechanics to ask here. I recently purchased this frame from a fellow on CL, and it didn't have a fork. I believe it's an '87, but don't quote me. I have no camera, but it is this exact bike frame I have https://fredhaj.tripod.com/schwinnpremispage.html. I tried searching but couldn't find anything regarding finding a fork for it. Where should I look? How can I be sure that it will fit? Thanks a lot! Also, the frame size is 62cm.

Are you looking for an exact replacement fork? You will have to be very patient and/or lucky to find one that is an exact match.
If you're just looking for a suitable replacement fork, get a fork made for 700c wheels, with a 1" steer tube. You will need to make sure the steer tube length is long enough to fit your head tube. 'Long enough' depends on whether you use a threaded or threadless fork and on the headset stack height. As usual, too much is better than not enough
since the fork can be cut down if it's too long but if it's too short you're SOL.
Finally, the fork offset and rake will affect how the bike handles. Unless you know you want to change the handling from a standard Premis, find out what the offset and rake of the original fork is and match that.
There are other subtle differences in forks, such as the number of mounting points on the dropouts for fenders, recessed vs non-recessed brake mounts, French threading vs 'English' hint: you don't want French
Really, though, if you just get a generic 1" road fork you'll be fine. French threads, 27" wheels, nutted brakes, etc are all obsolete nowadays. Your frame is modern enough that it will accept nearly any modern fork as long as it has a 1" steerer. Nashbar, Performance and most on-line retailers probably stock forks that will work, just make sure the steer tube is long enough.
