for the past two and a half weeks i have not been able to do any biking class. and now that i can do it i have a torn tube and cant ride so i am still doing tests on each chapter in the " its nto about the bike" book. i have been out of class 7 times and i have only read about 5 chapters so i will finsih it all as soon as possible. but in the mean time i have aslo been woking on my bike quite often and i thin kthat everything works great and i cant realy tell until i ride it. but it wil be working soon. i checked the tire for and thorns in it and i can find anything. so i guess its the way that im putting it on. ill use a plastic tire lever next time and ill make shure that no pinch flats happen. i do not know when i can go adn get a new tube and my other bike is out of commision due to a broken derailur and hanger and a moderatly bent rim. but as soon as i can get a new tube i will be riding and trying to make up for my lost days. i know that there is only about three more riding days but ill be on the road soon!
