Project 321 Boost Quiet IS-Disc Rear Hub, 32h,12x148mm (MS) - Blk
  • Very low drag freehub. Quiet pawls produce 68% less drag than previous system, loud pawls produce 51% less
  • 6x2 pawl driver yields 1.7 deg engagement
  • Fine pitch bearing preload adjustment allows for zero play and compensation for bearing wear
  • Machined pockets in drive chamber allow for 25% more oil than competitors to dampen sound and extend time between service
  • Flange angles allow the spokes to only touch at the bend of the spoke and nowhere else create a more stable wheel and eliminate unnecessary stress on the spoke
  • Rotor bolt holes are form-tapped which creates a stronger, cleaner thread than the more common method of cut tapping
  • Made in the USA
