Wow! this is actually really helpful. I like my alu langster's feel but The TK2 is not alu, but carbon, titanium and scandium, but close enough. The stem/headstock components would be comparable if not identical... it is a cut and paste from bikeworks' kit spec for the kit I can afford.

As far as wheels I have a Paul high flange hub w/ open pros, so I think that those are pretty good.

I was pretty psyched for the TK2 but my intuition started leaning towards the Soma and now I think that is the right way to go.
