Thanks scooper. Now that you point out steerer tube, the answerbtommy question seems obvious and I feel like an idiot for not realizing that. I inferred from the info I had seen about there being different "fork sizes" the difference was in blades and never even considered the obvious differences in steerer different frame sizes would entail. I would assume the 355mm length is crown to axel but if you could post a measurement from your fork, I would appreciate that. The steerer length on the fork I have now is right for me so I don't need that.
