Hey guys... I had a question about my Medici's drive train. Not sure why I just noticed it, but for some reason I was cleaning my bike and realized that the drivetrain isn't as smooth as my Peugeot. I'm not sure if this is even a concern or not.

I don't notice any stiffness when riding, but when I slowly turn the cranks or give it a spin with my hands it just isn't as smooth. Everything has been taken apart and cleaned/lubed. The chain is brand new and now stiff links. The crank and derailleurs were lined up correctly.

What do you guys think it might be? Or am I just making something out of nothing? Maybe I need to be a bit more thorough and try different gear combos as well as I only tried the big chainring and 3rd gear.
