the Felt probably is a step forward - the TK1 was designed in 2007 and I'm sure that Felt's engineers had a long list of things they could improve that they noticed over time. It's just interesting that it's not the same step forward that all the other bikes this olympic cycle are taking - there, we're seeing a lot of the same design elements - a hinged fork, one-piece bar/stem, stem/toptube integration, a lot of 3d-printed titanium. None of that here.
