I just purchased a Schwinn Mirada off of Craigslist. It has 26" wheels (not 650B), so I believe it is a 91 or 92 model. I'm not 100% sure though.
It came with nice fenders, and the wheels are in good shape. The crankset is a Shimano 200GS with Biopace rings that are in good shape. The rear derailer is the bottom end Shimano model from that era. It doesn't shift very smoothly, and I just adjusted it as best as it can get. The bottom bracket seems like it needs to be replaced as well.
My goal with this bike is to use it for some weekend touring trips and rain commuting/errands. I would like to replace the bottom bracket and rear derailler, as well as get some drop handlebars and bar end shifters.
Will bar end shifters and a new rear derailler (Deore or LX) both work with the 6spd rear gears? I don't mind the shifting being friction.
Is there anything else that you all think I should do to this bike? Also, does anyone know what steel material that the frame is made of? I've seen a couple listed on Craigslist as having Chromoly steel, but there are not any markings on the frame.
