    How much stem above the steerer is too much?

    I'm considering a new frame and hoping to use my current shock fork for the build. Given the length of the steerer, the length of the head tube and the total stack height of the headset and stem I calculate there will be 4.85mm of the stem above the steerer. Is this too much for safe use? Steel steerer and XC use, no jumping, drops, tricks, etc. (I'm too old for that). Components are RockShox SID 80mm shock fork, FSA XC115 stem, Ritchey WCS headset (integrated). 184.15mm steerer, 145mm headtube, 9mm headset stack height, 35mm stem stack height.

    it's close - just make sure the highest pinch-bolt for your stem is below the height of the steerer.
    Honestly... ahh I give up

    According to the FSA Stem Installation instructions, you should "leave a 3-5mm gap between the top of the stem & top of the steertube for proper headset adjustment."

    So, assuming you've calculated correctly, you have exactly the right amount of gap.
