I am joking - you are perfectly welcome to your opinions - I know I have them about just about everything - but can I ask you why you don't regard Michelin as a serious tyre brand? Is this just a cycle tyre thing or in general?
Just a thought, but I wonder if Michelin's image is harmed by a lack of presence at the top level of professional sport?
If you asked me to name the tyre I most associate with professional road racing, it'd be the Vittoria Corsa, or maybe the Continental Competition. Time trialling? Conti Tempo. Spring classics? Vittoria Pave. Track? Conti Tempo or Sonderklasse.
If I buy Vittoria or Conti tyres, I feel I'm getting the same technology used and trusted by the world's top riders. With Michelin, I don't get that.
Obviously, breaking into top-level pro sport would be expensive for Michelin, given that all the tyres listed above are tubulars, and Michelin's current capabilities are focussed around clincher tyres. But you might benefit from developing a high-end tubular, and getting it onto a Protour team's bikes, possibly making a loss on it, but making the money back through increased clincher sales? It would certainly strengthen the "premium brand" image.
