Hey guys, having a minor problem that I can't seem to dial out. The bike shifts fine, and adjusting the derailleurs doesn't seem to make a difference to this rough feeling. The chain isn't skipping, and it isn't visibly rubbing on anything, but when I pedal, especially when going slower, something feels rough through the pedals. The pedals themselves feel fine when spun on their own, and I still get some of the rough feeling when hand-turning the cranks by the crankset itself.

This is on a bike I bought new (but last year's model) about 6 weeks ago, so I'd be surprised if the chain or cassette have gotten worn down significantly in that time, even though I ride it as my primary transportation.

I'll probably stop by the shop at some point and have them take a look, but I wanted to see if anyone here had any thoughts.
