    Older GT brand road bike info

    I am trying to find out info on the GT brand road bikes. I have been unable to find a thread about GT on this forum, or maybe just missed it. If anyone has info on these bikes, I would appreciate direction to a thread or just your input on them. I am looking at a GT road bike with down tube shifters. Haven't seen it in person yet so no info on date of manufacture. I suppose mid 80's? Any recommendations on GT bikes in terms of quality and value of that vintage would be greatly appreciated.

    The only thing I remember about GT road frames is that they had a unique detail at the seatpost area of the frame. Basically, instead of seat stays connecting from the back of of top of the seat tube, the seat stays cross over the seat tube well below the seatpost bolt area. The seat stays connect about 1/3 of the way up the top tube toward the headtube creating an extra little triangle within the main triangle. Also, because the seatstays go in a lower angle, the rear triangle now looks different. I think these GT frames came like this in both steel tube and a really cool titanium version. I like the design personally, though some will be turned off by the look. I think there are some sound engineering priciples that went into it relating to the rigidity of the frame being enhance but no increase in harshness, maybe with a slight reduction in frame weight as well.

    That stay style is called "hellenic", I believe. Not unique to GT, though they used it a lot. Here's a pretty earlier example, decidedly not a GT:

    The style was also used by Shogun and a few other manufacturers as well. Very cool looking no matter who made it!

    The sound engineering that you speak of it formation of an additional triangle. Triangles are the strongest geometric shape known. Double diamond shaped designs found on most road bikes form two triangles. The GT has three making it more rigid and stiff causing it to be more responsive.

    The old GT "triple triangle." Man, that used to get debated all the time among mountain bikers. "Makes it stonger!" "No it doesn't!" "Makes it heavier!?" "Yep."

    PM me. I sold GT's for years, worked for one of their distributors back when they introduced road bikes, and sat through many of their global distributors meetings back in the ninties, and own a barn full of their best classics.

    Whoa! Pics! I am a GT fanboy and have an old 1990 GT Karskoram mountian bike that I love. There are 3 GT auctions I am watching now on eBay, two for titanium models. What is the ride of the GT road bike like? I have heard it is a bit stiff. Have you got a titanium GT? Back when I liked to mountain bike, my dream bike was the polished aluminium Zaskar. What a ride! My Karakoram is still kicking and still great.

    Jet, I sold a ton of those 90 Karakorams. I'm buried with the holidays but I'll try to get some pics on this weekend. Have two Xizang Ti mountain bikes in the stable, A very rare mint 10 yr old 24" wheeled Zaskar that I built this fall for my 10 yr old daughter rides/races, A mint 10yr old Edge Aero Aluminum Ultegra equiped road bike that had never touched the ground until this past July, Avalanche in Tange Prestige steel (pre-aluminum days, pre Xizang) and at least a half dozen others that were built up. The only empty stall in the barn is the one that says GT Edge Ti (road bike) above it. I will fill that someday but want to wait for the original first generation 95-6 vintage high polished one to come along. I'm not interested in the one that was produced under contract by Litespeed from 98-01

    Is this one the Litespeed one? Who made the 1995 one? GT?

    Very informative post, take your time with the pics, they sound well worth the wait

    From what I can see of this one it was a Litespeed because it appears to be a bead blasted finish. The originals were produced by Sandvik (TST) and had high polished finishes. The dropouts were different also. The chainstays appear to be a larger diameter on the one in this link also.
