I raced in the pro class and wrench for money.Huh? I'm confused. Does your particular bike model NOT... have a chain guide on the swingarm mounted just in front of the rear sprocket? Cause if it does have one.. then the only way you'd have that happen, it pitching a chain? Would be if it was HORRIBLY loose with too much freeplay and slack in the chain. Or you snapped a link.
If you go ride north Idaho and are the guy breaking trail....it's incredibly thick. I've bombed plenty of parts on the mountain.
For a fire road bike....I like a water cooled bike with better legs. For hunting....I don't want anything that can get ripped off.
