Excuse my ignorance, I bought a giant nrs2 frame, I’ve purchased new forks but I’m a bit stuck as to what I need to fit them correctly. There’s a bearing in each end of the steerer tube and it came with a rubber dust cap but no centre cap with a Allen bolt to hold the forks in place. I’ve also seen on YouTube a crown race fitted to forks before assembly any help much appreciated

    The bit on the frame is the head tube, the bit on the forks is the steerer tube.

    You need a crown race on the forks that is compatible with the particular bearing the headset uses (not all are the same and cartridge and open ball crown races are totally different) you need the compression wedge and then dust cap at the top.

    The Allen bolt doesn't 'hold the forks in place' it preloads the bearings while you do up the stem which then 'holds the fork in place'.
