Yea? Ok cool, now, looking at my measuring method I'm getting 382... What am I doing wrong?
You're getting a shorter length because a) with your method you're measuring the base of a triangle rather than the hypotenuse, b) you're measuring to the top of a skewer sitting in the dropouts rather than to the centre of the wheel spindle, this in itself accounts for a 4.5mm difference..
Well... ok, I see my original error... If you look at where the skewer you can see that the edge of the skewer that I'm measuring is maybe 1.5mm lower than the actual center of where the axle would end up... so really I should have reported the measurement to be 380.5.....
Now, if you draw up a little triangle and bust out Pythagorean Theorem (excuse my spelling) you will see that the hypotenuse is reallllly only about 3mm longer...
380.5 plus three is only 383.5
soooo where's that other 6.5mm ??
BTW the fork legs are at their longest point in the crown... They can be made shorter but where they are set now they can Not be lengthened without sinking them into the crown below the surface... (which I assume is not meant to be done...)
