dropping chain
Just built up bike
105 rear derailleur with a sram force crank, Running 9 speed and A single 39t ring in front right now as I dont have a front derailleur and was hoping to keep it 1x9
I used an old chain which I think might be my problem, but in my stand everything was smooth. Shifting was crisp, nothing seemed to be out of place
Im thinking I either need a new chainring or chain, my cassette should be fine, and I thought the chainring was fine because the teeth looked good but I could be wrong. They are not visibly worn down much.
I rode it to work this morning and everytime I came out of a stop the chain would click/clunk... and seem to fall off near the front of the ring. Really bad in traffic...
I have a chain guard on it right now which is keeping me from completely loosing the chain
But my knee is in great pain from all the chain dropping.
anyways any insight. Thx!
