I have an old (guessing early 1980s) Specialized Sirrus road bike with Shimano 105 gears (10 speed). As I am an older rider, the drop handle bars are real rough on my shoulders and arms. Also, the gearing is not adequate because I live in a hilly area.
Is it worth it trying to upgrade this bike or should I just get rid of it? If I try to sell it, how much should I ask?
