Is it just me, the lumbar support of the seat to me is great. I had back surgery two years ago which has left me with Fail Back Syndrone and dibilitating siatica down both legs. So maintaining good posture is important to minimize discomfort and pain. The firmness in the lumbar area of the seat is great. Granted no matter how firm I still can't sit for prolonged periods of time but the firmness helps to make the ride enjoyable. I've only put 18 miles on in the month I had the sxs. I hope the seat holds up as I have no intention of giving up my ride.
