Question for people that have repacked bearings on MKS pedals and the like: Did your pedals ever spin slower after the overhaul? I know spinning slower doesn't mean it's gotten worse, but my left pedal feels a little gritty. I've checked the races and they seem fine. I even re-cleaned it and packed it full of grease....still not a smooth roll. Should I just tighten it down to a semi-smooth roll and hope it pans out?
