I was talking to a friend about the reason why his single speed is dropping the chain when he puts a lot of power on it. I'm looking for any document that explores this and explains how it happens.
I know some bottom brackets, some cranks, some crank arms are stiffer than others, but I failed miserably in the search.
I'm asking here because the fixie folk knows about this better than the common riders
thanks in advance,
