Shopping for seats, and trying to figure out which will work with my rear loop. I tried to scale and superimpose the frame tubes into the image as accurately as I could. I think the Reed-Titan seat (RTS1, at lower right) will be the most suitable fit and most straightforward installation.
Most of their seats, including the Norton Proddie and Reed-Titan seat, are $131.41. That’s high, but doesn’t seem terribly unreasonable to me.
