I bought this bike to rehab after my first knee surgery in the 1980's, rode it 1x and couldn't do it. I've kept it in the garage hoping someday I could but, mult knee surgeries since so biking for any distance is not for me. It's all original, "lawlee design", triple butted chromolly, signature cranks, shimano light shifter, shimano brakes, original "sella italia" suede seat. Original tires also, although they are flat as you can see. Would just need to be cleaned up, new tires, etc. Can anyone tell me what it's worth?
