alright so last weekend i was at a race and went to check my sprocket bolts after practice and everyone was extremely loose, so i tightened them and thought no big deal. the next day i was at an organized practice and after the first practice they were all loose again. they came loose after every time i rode it that day. so after loosing 2 bolts that day i went and asked a buddy of mine for some sprocket bolts so he gave me some and i todl him what happened, he said that my hub is junk and that i need a new one because the holes ovalized and thats why they keep coming loose. he gave me thread lock to see if they just werent holding good enough. but sure enough i went out today and they were all loose again after 2 laps, and one fell out!!! i let the thread lock sit for well over 24 hours also. so what does everyone think? new hub? i need help fast too because i was hoping to make it to a race this weekend. thanks!
