I have recently started to get an annoying clunking noise from somewhere at the front of my bike (2003 Scott Elite Racing scottusa.comproddetail.phpOpen ↗) whenever I hit any reasonable sized bump. It's fine on road, but as soon as you go offroad it becomes very annoying and worrying sounding for such a new bike! I thought I'd isolated it to the supension forks (Manitou Axel Comp) but had those apart last night for the first time and really can't see any problems. There is no play in the front hub and the quick release is done up very tight (following all the posts about the danger of loose QRs and disc brakes). The wheel runs true and there are no loose spokes and the headset is free from play. It's definitely coming from the front end, so help, what am I missing?! Brake disc and caliper are all secure and the noise doesn't result from braking anyway, just rough terrain.
My only other idea is that between the headset and the stem there are two spacer rings and below that a thin blue plastic ring with a gap in it. I'm wondering whether this ring has cracked open and when under pressure can spring outwards leading to a momentarily loose headset stack. Unfortunately I'm usually too busy concentrating on riding to watch this and I cannot reproduce the clunking at all when I'm not riding the bike! Should the blue ring be continuous or is it meant to have a gap?

Do you have reflectors fitted? I had cluncking noises from my front wheel which I eventually diagnosed as the reflectors rotating about their spokes and hitting against the adjacent spokes. A bit obvious maybe, but it fooled me for a few days.
