The ad the guy wrote states 25" but I have yet to see the bike (I can ride a 25 no prob). Haven't even contacted him yet. Those wheels can't be the originals (?). Geezer, how do you like your ride? Tnxs for the input T-Mar. Methinks the guy selling this bike is sort of a low-grade flipper. Some guys really know their stuff and prep their bikes for sale in mechanically sound condition and I don't get that vibe from this guy based on other stuff he had listed in the past. This bike would be bought just for the frame, crank and brake calipers basically.
