Trash picked this baby. Got a 25.6 post and away we go. Then found although the tire said 26x1 3/8 they are really the obscure 650B tires or 584mm to be exact. For more info see this
site. Too bad the frame is small and I dislike the 165mm cranks but otherwise she is a great commuter. Just bought some fenders which are for 700mm(622mm) wheels fearing 26"(559mm) might be too small. Fun bike! Hope to get rack that will adjust to be horizontal. Hope the tires last, at $50/each it kinda defeats the whole economics of self propelled commuting!
Bike is a Raleigh of America MountainTour family. It says Yukon on the top tube. Too bad they did not put canti's on it! But for free I can't be too fussy!
