I know this is a stupid question. I don't know how to do anything on my bike but move the heights of the seat. I was suppose to be get trained on how to fix stuff but that person isn't around any more and well I don't know anyone else to teach me. I am thinking it should be fine since it the race is only a sprint(10 miles). I have not had any problems before with anything. So what do you all think? SHould I just hope for the best or what should I do?
