FSA front chain ring, Surly rear cog and SRAM chain (PC7x) that all are 1/8". I doubled check to make sure it wasn't the rear hub but that wasn't causing any noise at all when the chain wasn't attached. There is roughly 10mm of play in the chain along with the chainline being straight.
I googled to see if I could find any answers and the best one I could find which kind of makes sense is that sometimes components just need to be worn in but I believe these components have a few hundred miles on them at this point.. Is there something I'm missing? It's not rocket science, its 2 damn gears and a chain lol
Try a different brand rear cog. I've had problems with Surly cogs being noisy and rough in the past that was solved by changing to other brands like Soma and Shimano Dura Ace.
