Hi Brian, what's the special seat your having built ? , my seat is killing me on long rides would be very interested in what your findings are with your special, didn't you borrow a friends seat concepts seat when you first got your wr ? how was that compared to the standard seat, thanks steve.
It just shows what a subjective thing seat shape/design is. I find mine extremely comfortable as it, standard. It's just about as comfy as my armchair-like DR350 was.
