I swung and missed on a 531 framed Trek listed on CL, but the guy told me he was about to list a 1986 Schwinn Prelude in my size for $150. He says it's in good shape, pictures are forthcoming, with the only changes from stock being 105 aero brake levers and an x5000 rear derailleur. I'm looking for a second bike for running to the store and that sort of thing, so at $150, the price is just about right. Only changes I would make is maybe moustache bars, throw on a rear rack and fenders, and wider range chanrings if it comes with the standard 40/52 ... what was the stock crankset on it? Any comments on the Prelude in general, anything I should look out for, that sort of thing? Anyone know if it has a Helicomatic rear hub?
