How to Measure your Axle to Crown Length:
It is preferable to measure in millimeters, but anything you have can be converted with decent accuracy.
First remove the front wheel and place your thru-axle or quick release back in the fork. Pull on the lowers to make sure they are fully extended, sometimes stiction will occur and your measurement wont be accurate.
Measure from the top of the crown (bottom of Headset race), behind the Arch on the lowers, and to the center of the backside of the Axle. This should give you a measurement accurate within a couple millimeters.
