How can one identify titanium tubes on a frame, assuming there is no sticker identifying the materials?
I ask because a friend sent me a photo of a bike nearly identical (at least in terms of cosmetics) to my Titanium Eddy Merckx but which apparently is Scandium.
comparing them side by side however I see they are not really that similar. The Scandium frame seems to have larger tube diameters.
And where mine says "Titane" I think this other one says "Team SC".
But say you were just looking at a naked frame.
Titanium not steel? I presume that a magnet does not stick to a titanium frame?
Titanium and not Aluminum/Scandium? tube dimension? (would they weigh about about the same?)
ever curious, Peter
