Hi, i am extremely new to the world of 29ers. I ride a giant rincon around the city, and sometimes extremely novice trails. My budget is really low, nothing higher than 650. And this bike looks like my only option. i was just wondering why this bike is soo much cheaper than the other 29ers on the market. would i really be getting what i payed for? what would break? i dont do any hardcore mountain trails. just occasional dirt roads with some roots. and i ride around the city. please fill me in on the 411.
