threaded steerer length question
 

i have a 100mm headtube. my headset stack height is 34mm from crown race seat to top of adjustable race. i have been offered a fork with threading that starts at 125mm. is there enough thread to work?

please tell me how far below the adjustable race threading needs to start

Are there at least 9mm of threads?

100+34 = 134.
125+9 = 134.

I think this would work.

is that the rule of thumb? minimum 9mm?

no i think hes just saying that if there is atleast 9mm of threading then it will come out even. i dont think thats like the official minimum. But that would come out to your 134mm curent length.

I don't know eddie. I'm just doing the math with the numbers you gave me.
