I've done trials with this and trail really does effet the ride more. The thing is when you look at bikes with say a higher BB it also has other differences. Find a bike that is "the same" as another with a higher bb. Now start changing the trail without changing the other factors and you'll see the differences. Lake your bike with long dropouts and ride it with the wheel all the way forward in the dropouts. Next try it with the wheel all the way back in the dropouts and see how much of a different you feel. I've done all these things and more to figure out how different things affect he ride of a bike and in every instance a little change in trail has been the most. Alas, you'll have to take my word for it unless you want to try the experiments yourself. enjoy, Brandon"monkeyman"Ives
