drive train slipping?
lately while riding i keep experiencing these random jolts when i mash down on my pedals or skip/skid. i had my bottom bracket glanced at when i was in the shop to pick up a couple things and he said he didn't think it was the bottom bracket, then tightened my chain because he figured it was the slack slipping over the teeth of my chainring. we did that and i was out of there with no problems until a couple hours later when i felt it slipping. i know my best bet is to take it to a shop again and just have the BB looked at a little bit more seriously, but if its not that then i really dont know what it would be.
