It looks to be in good shape but the seat post is too short so I don't yet have a good sense of what it will fit like. It looks like it has some very shallow ischial depressions but it's not too obviously deformed. Today I went to a couple of stores but I wasn't able to buy a straight replacement post that works with the seatpost clamp. The bike store measured the seat tube opening at 25.8, and they only had a 25.4 post and the built in clamp didn't work with the double seat rails.
I also want to find our more about the Raleigh Century, but I guess it's way too new for this forum.
Thanks
Robert
