Well not sure i'm quite old school but here goes -
My first bike in the late 70's was a Roadking dragster, which some older lads reckoned I couldn't ride a bike with Roadking on it unless I passed their initiation, I came close (to killing myself that is

!)
In about 81 I got my first bmx a Voodoo (noname with aftermarket cobra grips and a numberplate) awesome I loved that beast until I found out it was a boat anchor when I started racing in about 85.
Next was an old Diamondback frame and forks in about 1986 I found in the neighbours yard and scored for a song. I built her up with the parts from the Voodoo then slowly got araya rims, kashimax seat etc etc.
Then in 87 I was getting a little more serious and decided to get a complete Kuwahara from a local guy that was pretty good (Shane Keene).
Next in early 88 I got a complete Tajh also from Shane which was an awsome bike and would love another if anyone has one. I remember when I got it I couldn't sleep, I had it in the laundry and I just kept getting up and going to look at it. It was long and low with chrome on chrome the whole shebang!
Then late 88 I had a brief encounter with a Boss Freestyle which lasted about 2 months...... until I decided racing was for me and scored a sponsorship deal with the local bike shop and they got me a team Boss F&F and a Boss race suit which I still have. This was a good solid bike with some of the gear from the Tajh and a few new bits like big arse Revcore bars, Beartrap pedals, Boss Alloy headstem and Boss cranks. I also wish I still had this "my last race bike". I have been trying to find her but in the mean time I do have another Boss with exactly the same F&F but not mine if you know what I mean, it has 1 piece Takagi cranks, DX pedals, Peregrine clamp, old round looking Araya rims and Robinson Bars. If all else fails and I dont track the original, I am searching for the parts.
I tried the MTB thing in about 2003 a shiny new alloy Avanti, but Iv'e decided that gears and shocks are not for me (unless it has an engine, but that's another story, for another forum) so it lives in the shed for visitors etc.
Last but not least I just purchased a yellow and black Gary Fischer (never heard of them till I bought it so who knows what it's like) which I am off to collect at chrissy from my brothers in Hervey Bay.
What I really loved from the late 80's was Bullseye hubs and GT's for some reason probably because I never had them.
