Thanks Scooper. I have not seen the first method of measuring forks before, only ever seen the axle to crown line parallel to the steerer. I sort of thought 355 seemed on the short side.
Yep; I'm not sure why Schwinn chose to measure the "fork height" that way. IMHO, it's not nearly as useful as either axle-to-crown race seat (straight line) or axle to crown race seat (parallel to the steerer) because it lacks the dimension between the brake hole in the crown and the crown race seat.
Nevertheless, it is used often enough for BikeCAD to include it in describing fork length. It is dimension "K" on the fork measurements page. "L" is the length from the axle to crown race seat (parallel to the steerer), and the cell labeled "L" can be alternately chosen "AC", which is axle to crown race seat (straight line).
These are the actual dimensions taken from the fork.
