I recently set up my Cotic Soul with a singlespeed parts set, which usually lauguishes in my spares box.
The parts consist of: an On One Doofer tensioner (looks generic - threads in to where the derailleur goes), a 16T cog in place of the cassette, a shortened XTR 10-speed chain and a 32T XT M780 ring up front. I have a feeling that those last two parts are the culprits...
It all works fine until I put a lot of torque down through the cranks - e.g. when going up a steep incline. The chain stays on, but "bangs" a lot.
Do I need a dedicated (non-ramped) chainset ring and (wider) chain? Would a chain guide help?
