got chased while going through a bad part of town (MUP cuts through it). I had just climed a really steep hill very slowly because its almost too small for a bike and snakes sharply...the dog started giving chase and i hammered down....giving 100% effort and then some, i realized i wasn't moving more than 16mph-17mph at most....looked down and saw i was in my small ring...

I know from experience most dogs just like the chase...they don't intend on biting...but i wouldn't take the chance.
