G'day, i'm currently living in sydney and am 18, and want to get involved in cycling. The problem is i dont really know where to start. I want to spend around aud $1600 on bike and acessories, currently looking at new giant ocr2 (2005). Should i join a club if i'm not sure if i want to race or not? and should i look for second hand bikes over new ones and where from? what do i need to do and buy, what is necessary for maintenance and where do i learn to do it, and what is recommended for someone like me who really doesnt know much about cycling? thanx.
