Being a car guy and autocrosser, I'm familiar with suspension systems and the necessity to find a balanced spring/shock combination to create the best possible compliance, ride quality and performance in the suspension.
So I can't help but think that the Isospeed technology on the new Trek Domane is a little odd as it's essentially all spring and no damper. Aren't you going to essentially have undamped motion while riding? For example, you can see the bounce in this video...
I haven't ridden one of these bikes yet, but I'm not sure if a short test ride would be enough to make a proper assessment.
And I know this isn't exactly a conventional spring. So I suppose my question is if there's anything about Isospeed that gives it some sort of damping characteristics to minimize excessive bounce?
