GT road bike?
I'm not sure why 
but I'm thinking about trying to find one of these to restore. Were they available in both aluminum and steel? Were they heavier than a standard frame bike? How did they ride?

Were you thinking of the triple-triangle frames? I have only seen those in steel. They would be very slightly heavier than a more conventional frame because of the extra tubing. I have never had the privilege of riding one, but I hope someone here has.

They are cool, the early ones were steel but I am pretty sure that GT also made them in alloy at one point.
Link to a story on them, very cool! https://www.roadbikeaction.com/fly.as...xid=96&cid=141

I would think that the GT triple triange frame design would make for very, very little weight difference as compared to a more traditional frame design, not much added tubing. Probably much more weight variation possible due to the tubing materials and joinery techniques used. GT road bikes were available built with steel, aluminum, aluminum-scandium and titanium. GT briefly sponsored Lotto and Jelly-Belly pro teams and I recall that they also once sponsored the US-national amature team. Seems to me that GT road bikes never really gained much acceptance for road racing. One of the few road GTs I ever remember encountering "in the wild" was Chan McRae's national team issue GT, probably right around 1992 or 1993.

I just picked up a couple of GT MTBs (I know I have sworn off buying any more MTBs....) at my favorite thrift store, and they used the steel triple triangle frame for those bikes as well (both cromoly frames). So there is a wide variety of them out there.

I ride an aluminum force with a steel tange fork till I come across an aluminum fork with the rake I like.
I don't like the triple triangle look too much but the bike rides surprsingly nice for 6061, really no complaints, actually ive owned a few columbus sl frames, such as colnago.. marinoni and this thing is just as good. I have a mis match of parts but a lot of dura ace, not sure on the weight but im thinking about 18 pounds complete bike, that steel fork is pretty heavy, plus I run a cheaper SR stem/bar combo.

I've got a zr 4000 - RSX group, so somewhere in the middle of the line. Haven't weighed it, but it's light to me - it's my only bike that isn't lugged steel! It's my "modern" bike
