^ good point.

Fork checklist:

1. same diameter steerer
2. threaded / threadless - must match headset
3. same brake mounts
4. long enough steerer tube, and for threaded, enough of a threaded area if you're going to cut fork down.
5. approximate axle to crown race dimension, or deal with possibly wack steering and increased pedal strike OR compensate with differing front/rear tire sizes.
