i am from adelaide and 2days ago i went to a chiropactor down in west lakes. this guy really fixed me up and told me what was causing my lower back problems. my problem came from my jaw which causes other parts in my body to not function right and which caused problems in my hips and lower back. i was in a car accident 4yrs and my jaw and side of my face smashed the drivers window. i didnt even tell him that and he knew.... anyways cut the story short, i recommend this guy (his name is Brad) to anyone that has lower back problems because when riding a bike on a long trip, your back gets sore. anyways it has helped me able to turn right alot better now. i think my hip and back was too tight before but now thats been fixed, its helped me alot in my riding.
