I am currently riding a 2006 Fuji Team Pro 54 cm. I am leaning towards switching it out for a 52 cm. Though I fit a 54 cm I think a 52 cm would fit me better and would ease the effort in getting on and off the bike. I am a recreational rider so since I was trying to get another size, what is comparable this current bike that I have or should I just get a newer model of the same bike in the new size? Any idea how much my I should be asking for my bike on the used bike market? Thanks
