Also, evaluate the fore/aft position of the saddle. I reconditioned an old Fuji Special Road Racer, and didn't bother adjusting the saddle position when I took it for a test ride. My knees hurt for a couple of days, afterward. I blamed the '70s gearing and Pennsylvania hills, but, when I took it out, the next time, I noticed the saddle was too far forward. After moving it back about an inch, the hills were (slightly!) easier, and no knee pain. I may have to keep this one.
