Hello
I'll be clear.
The Z team color you have is the 1990. This colors doesn't exist in 1989.
In 1989 Lemond used a TVT Team ADR in yellow and black.
For 1990 and Z team they just complet with pink color.
As i say before , you only need the TVT top tub and the front GL sticker.
Drop in is perfect for this bike , your are lucky to find a 42 cc , i only find 44 which is to big for me...............
For the 1989's victory in tour france stickers , it's annouced the victory of TVT (with lemond and ADR) one year ago ......at the beginning of 1990 they can't put this sticker on the bike besause for sure they don't know than they are going to win the Tour 6 months later........logic
I give you an exemple which can be compared.
You buy a car in 2001 which has been proclamed car of the year 2000 and on the car , there will be a sticker with 2000 car of the year , whatever you buy the car in 2001 -2002 .....2010.
Do you understand.
So you can be sure your bike is an 1990's bike but coming from a shop with Z team configuration.
The team 90 TVT bike with Z team color (but without the stickers !!!) is the official team copy from TVT for 1990.
