Greetings fellow bikers: I just bought (about 4 hours ago) a TREK 4300 and I noticed it had a significant amount of play in the crank area. I can move the pedel up and down, but there is no play from side to side. I am a pretty good fixer of various mechanical things, but know little to nothing about bikes. What do I do to fix this or where on the internet do I go to find a detailed breakdown of the crankset so I can tear it apart myself. Also could use some info on how to adjust the front and rear derailers. Your help would be much appreciated. George 702 768-6012 Henderson Nevada.
