yeah... I'll give that a try once i'm done eating... I was just wondering if there's any possibility that it might be the BB. It doesn't happen everytime I skid/skip and there seems to be no connection between it slipping when pedaling and back pedaling. The two incidents with it slipping when starting to pedal was when i first got the bike and hasn't happened in a while and then this skidding issue wasn't followed by the pedals slipping when pedaling forward and i was going up the biggest hill on my ride right afterwards.

Also the hub, cog, and chainring were professionally installed and brand new... the bb came with the bike which was a garbage find.
