I didn't catch, 3/32 or 1/8 ?
points of interest:
-Steel dosn't stretch, bushings wear out. Period.
-No matter what brand the chain is, its bad to make it reealllyyy tight.
-Even the cheapest KMC chain wouldn't do that if it was tensioned properly. Remember that the condition of your botom bracket and rear hub greatly affect your chain's desire to stay on. If you have play in either you may *think* your chain is tight when really it wants to say 'Cya'.
I'm currious, if this guy wrecked bad would anyone wake up and put a front brake on? I doubt it.
