My guess is that it is a 1989 Tange MTB tubing (triple butted), internally routed rear brake cable, semi-horizontal dropouts, with 1'' threaded headset, eh, 15'' or 14.5'' frame? My fork couldn't take a modern 2.1 wide tires - how's yours? Also a biotch to find any decent replacement forks due to headtube designed to take JIS 1'' headset (be careful with this replacement as JIS 1'' isn't the same as "standard" 1'').

EDIT - oh you now posted, it's an '88 frame, probably '88 model year too. I think it's Jan?

Wow,year88!!:thumbsup: Thanks for your info!!

I guess, with the fork, mine has the same clearlance for tires.
So, Do you think the 2.0 tires is the max for the fork???

I heard that some of old GT was made in Japan.. so was mine too??

Thanks for the image!! :)
I really like the "Cracked" paint. There is somethin' about 80's bike.

I think i might get 2 .0 Tires as in the katalouge shown.
Though, I am not sure Slick or Semi Block Tires.

As for tires, I was trying to stuff a large casing tires - bad choice. So any standard tires less than 2.1 should fit ok. It's just that I only had a hair space between tire treads and fork column, that it made contact from the fork flex upon cranking hard. Biopace looks just fun.

I don't know for sure but Toyo made Team Avalanche but not anything lower. I thought "T" in the serial number was Toyo but then Toyo build frame seem to have different type of serial numbers and BB shell. I've asked them repeatedly what year and makes that they produced in the late 80s but they've been blowing me off. Oh well.

I was going to suggest a strip and repaint. Did it managed to fade or it's using different shade of grays?

I might try to contact Toyo about my Karakoram.

I did little gray shade paint and drew cracking pattern with a bush.
I have not finished it yet.

I will definitely keep the cracking paint alive :D

Hmm, let us know how your conversation with Toyo goes. They seem to be much more into road bikes and custom frames.

I got a message from Toyo. I am disappointed the way they reply...

They said " If you bought the bike in Japan, it is made in Japan." (period...)

:eek:

oh well, it doesn't matter where it was built, I will enjoy my GT restoration.

Sounds like a standard Japanese runaround and somehow that doesn't surprise me:)

Yeah enjoy the bike, it's a classic rider, any way you look at it. I'm shocked that it doesn't look all that rusted in your pic, for it is in Japan. It would make a fine commuter too.

Diggin this up from the dead. Yes, that is an 88, and yes it is made in Japan. I have the same bike, bought it new, only in red, the other color offered that year. I wanted the black crackled paint so bad, but no lbs had one in stock so I settled. Great bike, good luck with it, and whatever you do, don't re-paint it!
