I found a bike locally with this frame in all reality i want bike more for components but was curious in the frame guy said he paid 1200 7yrs ago for it hes only ashing 300 its got ultegra on it with mavic open wheels and look pedals. Also if its even a decent frameh how would i go about making sure that its in good shape i know titanium is hard to weld and if not done right could result in injury? Thank
