I'm putting my new bike together and i'm trying to even out the chain tension. I know what i'm supposed to do with loosening ring bolts and then micro adjusting the tension, but it doesnt work. I checked and the chainring seems to be free of wobble, the cog has zero wobble, but there is still a big difference in tension between two opposite crank positions. I tried rotating the chainring position around to see if that was causing, but each time the tight/slack occurs at the same points. So what else? Chain tension is just about the worst thing about the fixed gear
