OK so after chatting to Steve (Firebird) and some Googling / Reminiscing, I have come up with the following parts list:
The bike as pictured features:
DP Freestyler Frame - White
DP Freestyler Forks - White
Tange MX2 Headset 1"
Tioga / Tange BB
Tioga Task Force 1pc Crank - Chrome
Shimano SX Copy Pedals - Gold
ACS Z Rims - White
ACS Z Hubs - White
Tioga Comp III Tyres - Probably Copies / other
Tioga Bars
Tioga Task Force Stem - Blue with a sanded back to silver top
AME Round Grips - White
Dia Compe MX1000 Copy - Rear only - I think this was also Blue sanded back to silver
Dia Compe Tech 4 Copy Lever - Rear only - Blue
Dia Compe Cable - Rear only - White
Tioga Task Force Seatclamp - Dark Blue or Black (striped one)
Kashi Aero Copy Seat - Blue
Tioga Seatpost - Chrome
I know I didn't always run one brake, so I will probably fit a front one too and at some point I know also fitted a Suntour Headlock in Blue....
Now I just need to find all the bits! (and afford them!)
