I'd be very interest in your comparisons to Serfas Rx because i have a few bikes and i have been slowly replacing the seats with Serfas Rx. So far so good for me. I ride up to 50 miles on road/touring bikes at a time and i have no discomfort with the Serfas seats which is more than i can say for any of the old seats my old bikes came with. I am curious about owning a Brooks but have so far avoided buying due to cost and theft factor. Just today i was at an LA Metro station by the bike parking and the security guard was telling me there is a theft problem with seats. People lock up the bikes but the seats get stolen. Im sure a lot of the stolen seats are on quick release seat tubes but maybe not all of them. So far nobody's stolen any of my seats but the only ones i hvae that are new models are Serfas Rx.
