The welds here are not those of aluminum alloy. You can compare them with the welds of the Zaskar AL, and there are slight differences in details from the Zaskar. Both the frame owner and I have aluminum, steel, and titanium frames, and we are both certain that this is a titanium alloy frame.Neither is / does alloy…..
It’s a 93/94 Zaskar frame which has been painted grey or bead blasted would be my guess.
Proving it’s Ti is quite easy …. What colour does it spark?
