Biking eye candy is one thing, whether production models or custom-framed.  But this butted-carbon VRZ2 track bike is ridiculously in the bike porn category; it incorporates carbon tubing and 3-D printed titanium lugs and dropouts.  Designed and handcrafted by Ralf Holleis.  Photos courtesy of VORWaeRTZ.
