Just wondering if anyone can tell me where the GT stamp is located on these bars. Is there a stamp at all?

I have an early 83 GT laidback seatpost and it's stamped "GT S.A. 4130 CrMo" (within a circle)

Height: 28" bar end to bar end
Rise: 7" rise from center of bottom tube to center of cross bar
Sweep: How do I accurately calculate this?
Weight: 1 lb. 12.1 ounces

Thanks for any and all information.

If there not stamped they most likely are 84 older. Is the cross bar thin (like Hutch) or thicker?? thick would be mid/late 80's... Weren't that all rediculously sweeped?? LOL!

Got a pic? that would really help... also the 7" height makes me think mid 80's

OK, here are the pics..

There shouldn't be a stamp on those....NICE BARS!!!!!!!


Jon

those are early ones. small crossbar

Yup, there 81-83ish. Where are you measuring the 7" from? No stamp on those years, just the decals.

My measurement is from the center of bottom bar (where the stem would clamp) to the center of the crossbar. In other words, the center of the tubing itself.

They came off a looptail PK Ripper that needs a new seatube! (Don't they all?)

I should have measured the rise to the center of the handlebars (the tubing that the grips slide onto). I'm not sure why I measured them the way that I did.

The rise is actually: 9-1/4" if I stand the bars on the workbench and then measure from the workbench top up to the center of the barend's tubing (where the grips would go).

What is the proper way to measure rise anyway?

They certainly were more square at the bottom than the later GT bars, weren't they?

Nice find! Can we see the PK?

I didn't read your "how you measured" description....sorry. I think there considered an 8" rise bar... You have 81-83 bars. I see most of the round GT decal on the left side, so something is telling me there possibly 81's....I'll into them

Thanks for all the info guys.....I knew they were old just because of the age of the other stuff that was with them is also fairly old.

Here's the PK Ripper frame:

Sweet frame!!!

You have snow already??? not so sweet!

No snow, that's picture was taken last March ! I hope this upcoming March isn't the same.

Our Winter's in MN are short these days( Yeah!). The past 10yrs we get the standing/staying snow around 3-4 week of Dec. and usually the freak Spring early March storm and its gone it 12yrs.. I think we got 22" all last Winter... Pretty strange around here the past decade.. No complaints though. The Summer's really hot and no rain. Then of course in Sept we get a Summer's worth of rain over night....LOL!!!
