So I dont know much about bikes and all the stuff like frame geometry and angles and all that stuff you guys thow around here. I want a cheap around ( preferably under) $800 hardtail 29er. I want it to have a front shock the travel doesnt really matter. I mostly ride dirt trails, with some rocks n stuff, with some large ups and downs. I am deciding between the diamondback overdrive, haro ally xc, and siren trauco. Also, building my own from a frame isnt an option. So which of these is the best, or good, or pros and cons, or if you guys have any other suggestions thatd be cool.
