I was actually wondering about that as well....why all the annoying whoop-la over dual suspension. I think the bike really dictates where you ride. When I used to ride out east, no one did, and to my knowledge not many people do ride duals....Out west people do, but the bikes call for the dual suspension more because of the rugged terrain. Also, dual suspension has gotten cheaper, so more people buy it. My problem with dual suspension is that when your pedaling up a hill the rear tire sags, and you loose your strength in your spinning. Now you can always get a shock that locks...but I've heard that to have the shock locked for extended periods while going up hills is bad for the frame. i've heard its bad for the frame because the frame was designed to flex at that focal point, and when you lock that point it makes the frame flex in areas where its not designed to flex and it cracks the frame eventually....many runon sentences in this reply, but its friday and I don't care !!!!
