I just ran across the Dugast Coupe du Mondes model which sounds like it has a more durable sidewall than previous models.
Milwaukee Bicycle Co. has a silk version of the Typhoon with the red sidewalls that is predictable spendy. World Class Cycles doesn't have them.
Does anyone know any further details? On first glance this looks like a step in the right direction for Dugast. If I can get Rhinos that last more than one or two race seasons I'll hand over my card right now. I bet lots of other people will, too.
