thanks guys, yes im definately gonna run a 3rd bearing, just waiting on axle to figure where to place it exactly, with me being a small guy, and a smaller seat, i believe i have room for the brake on the left side, which leaves me some more room on the right side for sprocket, just have to see, still kinda up in the air over a vertical with a ragb or a horizontal with a jackshaft, guess it depends on what i can find locally, i was reading Ryan that you were considering a 30'' twin, i have found a few of those, they pretty common around here, or more common anyways, whats your opinion on them?? again thanks guys!
