Specialised AIRFORCE 2 for me also ..... i still have it too - have only worn it once and it nearly killed me ! ( long story involving a very low bridge and me not ducking low enough ..... nearly too me 'ed off )
I used the Giro Lemond Air Attack in raed for a while, although I also really like the Hammerhead with marble print and yellow decals.
Coolest helmet ever though: Bell Whatsitsname with a custom Fat Chance airbrushed Yo Eddy team logo on it
A Bell was the first proper helmet I had (as below) think it was an "Image" before that I had a Lazer(sic) big hard plastic shell, more like a motorcycle helmet.
