I bought a secondhand suspension fork online and the steerer tube has been cut to 170mm which I thought was plenty from what I calculated, turns out not so much.
After doing a quick test install, the full stack height of the headset and stem brings the steerer tube exactly flush with the top of the stem.
I have some spacers coming tomorrow and plan to put a 5mm spacer underneath the stem to allow pre-load.
I am unsure if this is safe or alternatively if I should put the spacer on top of the stem. Could I risk the top bolt not clamping onto the steerer tube but putting the spacer under?
The third image is roughly what I plan to do with the spacer
Just reaching out for some advice as I only started learning about all this 2 weeks ago!
Is my plan sound?
