I just bought me a wethepeople darkness (2006), and a friend a mine bought a wtp thrillseeker frame (2005).
I just saw him today and we rode each other's bike and we both thought this frame suits me better, and since I'm alot taller then he is (my frame is 20.4 and his is 21") he suggested we'd exchange our frames. What I would like to know now is, is this a good deal for me?
And second, I would like to know the weight of a thrillseeker frame and a darkness frame.
I thank you all for your help.
