What kind of chain are you using? I have a sram 1051 chain and a 12x30t set up but cant get find a proper chain tension. I've tried taking links off and on, and going through the tension adjusters range. Sick build by the way!

 Thanks bro! It's just a Sram PC1 chain. Singlespeed. They're super cheap but last a while! I'm running a 14tx30t if that's any help
