Recently I purchased a used Keiser M3 from the gym that I work at. I know they usually do some routine maintenance on the bikes like calibration and what not but I never paid much attention to it. Now that I own the bike I am trying to figure out what I need to do and how often to keep the bike running smoothly. Any suggestions? Also I have a sticky SPD issue with one of the pedals. I keep twisting the cleat on my shoe trying to get it out of the pedal. Any fixes you can think of to help? Thanks in advance for your help!
