If you tighten your chain to the correct tension, even if you do so at the loosest point, it should not be anywhere near binding on the tight spot. If it is you are likely using a bio-pace ring. Seriously no chainring should be that out of round. I can move my chain almost a half inch up and down with my fingers, which means it has about 7/8ths inches of play. if your chain ring is almost an inch out of round, buy a new one please
