Is it possible to accurately determine headset stack height without disassembly....
...of the fork from the frame? (threaded headset)
(Dear God, please prevent me from submitting stupid questions on BikeForums.)
Measure the length of the frame's head tube end to end. Then measure the overall length from the fork's crown race to the top of the headset's lock nut. If there are any spacers between the headset's top race and the locknut, measure them too.
Stack Height = Overall Length - (headtube length + height of any spacers).
And no, this is NOT a stupid question.
What kind is it?
