GT PRO PERFORMER'S

[Swivel]

Sorry to start this debate but I'm sure someone can put me straight about this soon...

The performers started with 3 holes in the forks and 3 in the rear dropouts from 84 onwards, but when did they start with 4 in the front and rear? And did they revert back to 3 at all during manufacturing?

I think Munners and Wardy have to get involved in this one 

Cheers,

4 in the front and rear in 85 mate.

Ive got an 84 and its got 4 in the front and 3 in the back.

Basically if you want to know if its a US one.......as long as the rear left drop has a serial then it is a US.

Cheers Nick  , so there is no way an 85 or 86 model could have 3 in the front and 3 in the rear then? 

[munners]

84's = 3 in rear and either pro forks if an early one or 4 hole drops in front

85's =3 and 4 in rear and 4 in front.

86's = 4 in rear and 4 in front.

Hope that helps. Not 100% on the 86's as they aint my bag. Positive about 84 and 85's.


HOWEVER......Wardy had an 86 with 3 hole rear. It amazed everyone and blew everything up in the air.  Aparently these were ones that were US made tubing and later welded up in 86. I found that out from a guy in the US on ebay. I later showed Wardy what he told me and the question was at last answered!

Also Matt.....i have never seen 3 hole drops in the front.

A lot of 3 hole rear drop outs made their way into 85 bikes as the parts bin was used up.

So you need to look at other indicators too...

Platforms & other hardware changes:
1984 - Feb, Mar, April, May - Unstamped top tube end.
1984 - June onward - Stamped top tube end. The platform joined the top tube in the middle of the tube so that the platform was not level with the top. The fork legs extend past the dropouts.
1985 - The platform is joined at the top. Later half of 85, cable guides were added to the forks. The fork legs end at the drop outs.
1986 - Yuk. It all started going wrong. Some cheap mild steel shite started appearing on the lower end models, so be careful what you buy.

Serial Number:
Best way to tell though is from the serial number, the first four number are mmyy (month month year year) and they should be on the dropout for early frames and on the BB for far east frames. You can not tell the date on the far east serial numbers.

As Nick says, there were no 3 hole fork drop-outs. Only race forks on very early ones and 4 hole there after.

Hope this helps.

Certainly does Dave, thanks mate for the heads up and detail into each model

[WARDY]

Quality thread for a non GT guy, chaps! 

[WARDY]

Nick,  mine had 4 holes on the rear 

[munners]

I know. Thats why i doubted it!

Im a dick.

[WARDY]

im only saying that Nick as further up the post you said mine had 3 holes in

[munners]

thats why im a knob.

[Nosnod]

My 85 has 4 holes front & 3 holes back

I did some research in the overseas made Performers with serial numbers on bottom bracket and all the 1985 ones follow a common serial number pattern:

e.g.

G5C1739 - 1985 March #1739
G5D1588 - 1985 April #1588
G5F1084 - 1985 June #1084
