Disclaimer: after much research, I upgraded my roadie to a Specialized Roubaix SL2 with SRAM Rival late last year. I love it.
So I found the above Velonews link disturbing and disappointing. I really like the design features of Volagi bikes - designed for the riding (not racing) that I like to do. If they were available in Australia, I would have definitely test ridden one and may well have chosen one instead.
I find it hard to see too many infringements in the design of the Volagi. No Zertzs. Discs. Different seat stay layout.
I have no clue on IP/employment law, and the Velonews article is one-sided, but from a casual observer's point of view it seems that Specialized isn't doing itself any favours in the popularity stakes with this move.
