I can't tell you where I heard it because I forget.
I guess the logic follows if you're riding brakeless, you don't want your drivetrain to fail, so you go with the strongest out there.
but I agree that you would have to be a monster to break something. something my 155 lbs ain't.
so why "i rode 3/32" brakeless"? and not "i ride 3/32" brakeless"?
