I'm looking at a GT Edge and I want to figure out if the frame is titanium or aluminum. I'm sorry I don't have any pictures, but I was wonder what indicators there are of titanium or aluminum.
I've looked at it before and I'm leaning towards titanium, but I'm only 70% sure. The 94/95 model came in polished aluminum and polished titanium or steel. Its not magnetic, so that leaves aluminum or titanium. Titanium should be darker and aluminum brighter but its really hard to tell without reference. The welds look titanium - the pools are similar size to steel while aluminum welds have larger pools. I've welded titanium before and they have that really crisp look to them. This is why I'm leaning towards titanium.
But I'd like to be more sure before making an offer on it. The drivetrain is Dura Ace 7400. Here's a link to the '94 catalog. Anything else I can look for?
