Shared features

Complete wheelsets are hand-built   at NoTubes’ headquarters in Big Flats, New York. These new wheelsets roll on the company’s Neo hubset, which features a six-pawl freehub with 10-degrees of engagement. These hubsets are compatible with all major axle standards. The Flow CB7 and Baron CB7 carbon wheels are covered by a seven-year warranty and lifetime crash replacement for the original owner. Both wheelsets are available now.

    Both of these weigh the same despite rim width differences? Or is that a typo?

      Not a typo. According to NoTubes, it’s due to differences in the rim designs. While the Baron is wider, it’s not as tall as the Flow, which achieves some weight savings.
