I just swapped my stem for a slightly shorter stem. After i installed it, the cap wouldn't go on! I had to remove a spacer in order for the cap to go on but now i have a very slight gap between the gap and the new stem.

Is this ok? I have a feeling i should have just bought the stem from my LBS and had them install it. :(

    Not all stems have the same stack height, you'll need to fit another spacer onto the steerer to be able to adjust the tension properly.

    There should be NO gap between the top cap and the stem. If there is, you need to fit another spacer.
    I ride a bike. Doesn't make me green or a tree hugger. I drive a car too.

    you should have some spacer or stem overlapping the fork steerer tube so that the top cap sits above the fork steerer and can compress the headset bearings
