Check out this crazy ride from the late '80's. It's in pretty rough shape, but the uniqueness of it made me buy it. All this talk about "69'er's" (29" front wheel w/26" rear) is nothing new. Cannondale was doing this 24"/26" thing in the late 80's with the idea that the smaller 24" rear wheel would give better acceleration and handling in the tight east coast singletrack. I think Pintz Guzzled has a pink one of these that he uses to haul his kegs around. Seems like a valid use for such a weird bike. Come check it out if you're in the neighborhood.
