Did the Black Mountain downhill on Sunday and didn't notice anything that would cause damage. But then yesterday I went for a ride at Sherman, here's what went down:

Somewhere near the end of Roller coaster I went to shift back to my big ring after a climb and nothing happened. I stepped off and noticed that the rear derailleur seemed a little bent (not that this should affect shifting on the chainring) and kind of eased it back into place and was able to shift again. But then it happened again and a horrible creak started somewhere in the cranks/BB area. Think of the sound of a Walmart special with a rusted chain left out in the rain for two years and you'll have some idea of how my 2016 Stumpy sounds right now. Seems to come from the right side on a downward rotation.  Shifting is inconsistent. 

Thought it might be a busted pedal (the creak, not the shifting) so I swapped them out and it's still creaking/clicking when pressure is applied. 

Thoughts?

So you were in the tall gear in back and tried shifting to tall gear in front?  I think that is usually frowned upon.  It may have bent both the back and front mech.  But IANABM (I am not a bicycle mechanic) and there's probably a better opinion out there.

Thanks for the feedback so far. Yes, it is press fit and no, I was somewhere mid-cassette when shifting started acting up. I have cleaned and regreased the pedal spindles and the threads on the cranks, cleaned the cassette, lubed the the chain, etc. So all the basics are covered. It really sounds like a busted bearing in the pedal, but I switched them out and the noise was still there. 

I guess I'll start pulling and working the bottom bracket area / bolts next. 

PIA.

Good call, will do. Anyone know a good, reasonable torque wrench for bikes?
