Welcome to the list Grga. Unfortunately I can't help you with the tigra you posted about, it is an interesting looking bike. I did however once have a puch mistral. If I remember correctly my frame was actually made of columbus tubing. It was a nice frame, good workmanship, nice white pearlescent paint and of course a nice ride. I bought the frame off of ebay and built it up with shimano 600 components. Well I just figured I'd drop my quick opinion in the ring.
