Its been almost 6 months since i last posted or visted bikeforums.net. my life has been going up and down during that time (college graduation, job hunting...job hunting....job hunting). But i am glad to say that i finally have a job that i love..and it pays pretty good. So now im back in the urban jungle called NYC. Last time i checked, there are no dirt trails or stunts for me to play on. So now im considering a change. My Kona Dawg has served me wheel. I might sell it, or salvage it for parts, not sure as of yet. But im am in the market now for a urban assualt bike. I am looking at bikes such as the P3 and or Flow, something along those lines that will enjoy the most of this concrete playground. So my question to you, should i buy a complete bike OR buy a frame and build from the ground up. On one hand, i could buy the complete bike...done deal....OR buy the frame and slowly shop for parts and buy my own tools to put it together. I would guess there would be a learning curve but what i would learn would be invaulable in the future. Any thoughts or tips anyone could offer me?
