Mike Ahrens was kind enough to share some images of his 650B prototype. Photo'd here, it had just returned from the polishers. Hi-Shine! Nice Ahrens CS and SS yokes, dropouts and 7000 Series BB shells are available to frame builders, or tinkerers. Check out their page on the web at www.ahrensbicycles.com . They also sponsor the Vanderkitten Team. Meow. On top of all that, they produce the WISECRACKER, for your bottle opening pleasure!
