Howdy folks, I recently acquired a 1995, possibly a 1996 Cannondale R500. My dad bought it new, put maybe 50 miles on it, and it sat unused until 1999, when i rode it that entire summer, maybe put 400 miles on it, taking a break from my specialized mountain bike. Since then the bike has been hanging in the carport, unused...for 13 years. Well, I finally convinced him to let me have it cheap. I pulled it down today, cleaned it up, and it needs a TON of work. I am going to have the local bike shop look it over, but my big concern, there is a bracket near the rear derailer which holds the cable in place, it appears to have been held in place with a screw, the screw is broken, I am attaching photos...I am thinking it really needs everything, is it worth it to bring this one back from the dead?
