Thanks, Wahine.

I went into the LBS yesterday to have them do a once over of me and my bike, and it turns out one of my cleats was glaringly off kilter (so much so my mechanic called me a goof-ball). I went for a short ride, and there was not the internal grinding I usually feel with each pedal stroke. I'll keep rolling, but I think this was the source of the problem.

It's amazing how such a small thing can effect everything else!
