threadless headset

[FileStyle]

how does one determine the length of steer tube needed if buying a used fork with steer tube already cut? how much should fork steer tube be exposed to use stem and spacers? I currently have a threaded steer tube with external cups. my head set tube on frame measures 5 3/4" long.

I'm bumping this one, and moving it to the appropriate forum.

you might have to change the headset first so you have an accurate measurement
...I could be wrong tho...I have never converted between the 2 types yet

Headsets usually specify stack height. Add that to your headtube length + spacers + handlebar stem thickness.
