Will the fork fit?
I'm ride a 56cm bike and and looking to replace the 1" threaded fork. I found a threaded fork that is off a 60cm frame. Will this fit without having to cut the steerer tube and rethread? Thanks!

It's impossible to say unless you can measure them or find the specs for both your bikes on the head tube length. There's just too many designs out there to tell for sure. 56 to 60 is quite a jump so it is likely longer than your present fork. So cutting it down will likely be needed. The threading may or may not need to be extended. It depends on the length of the threaded portion. I've seem some that had 3 inches of threading and others that had only an inch.
This is why when threaded forks are sold they normally include the length of the steerer tube to the nearest mm or 1/16 of an inch for folks to be able to tell.

It may not fit unless the threaded section is long enough for the top race to thread down to the point needed to adjust the headset play. If the threads are long enough, which I think is unlikely, you will still have to use a fair stack of spacers between the top race and the lock nut to get it right if you don't want to cut it down.
To do it "by-the-book" you will have to cut it down and probably extend the treaded section significantly. The difference between a 56 and 60 cm frame is over 1-1/2" and the headtube and steerer lengths are going to be right around that difference too.
