Marketing 101: Ding the competition and boost your sales. Really sounds like an ad for Seven & Passoni.

There is no doubt that ti is a difficult frame material to work with, and must be back purged extensively to avoid weld contamination. But difficult does not equate to impossible.

I've had two ti frames in my life - a Quintana Roo Ti-Phoon tri bike (made by ABG, same group as Litespeed and Merlin) and an Indy Fab Crown Jewel. Both were really nicely made. Sold the Ti-Phoon because I wasn't into triathlon bikes anymore, but still have the IF. Interestingly, IF shot-peens their frames after welding to reduce stresses resulting from welding process, which I believe almost no other manufacturers do.
