Felt's B2 is a fantastic bike. It takes the very best of Felt's aerodynamic prowess and fits it into a traditional, non-proprietary package that lets you install pretty much any kind of components you like. This build represents the way I like this bike. The final result is a race-worthy machine that could easily best a lot of so-called 'superbikes' without resorting to a single integrated part or proprietary interface.
