What chainring/cog/chain combo are you using?
I've been running a Boone Ti Ring, PC830 and a Surly Cog. I get quite a few loud pops per ride. Not sure exactly what causes it...I assume it is some sort of chain engagement issue. I don't really feel it, but it sounds like it can't be good. It happens when the chain is loose or tight.
This is on a MootoX-YBB w/ m960 cranks. On a side note, the Boone teeth are further to one side of the chainring. With the bling side out, it nearly hit the chainstay and likely would have under flex. Hence, I am running it dull side out, and it clears sufficiently. Someday someone is going to get a good deal on this chainring.
I have a new symmetric Ti chainring being made by HBC. Also have a King cog on the way and a PC-7 1/8" chain, thinking that a little extra tolerance might keep it from popping. I hear they are noisy on the 3/32 components. We'll see.
