SKU: BTI-PT5021 Product qualifies for Free Shipping Project 321 Boost Loud IS-Disc Rear Hub, 28h, 12x148mm (XD) - Blk

  • Very low drag freehub. Loud pawls produce 51% less drag than previous system
  • 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 to 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
  • Industry leading warranty: 10 years on hub shell and axle, 3 years on pawls, drive ring, and freehub body and 1 year Enduro bearing warranty.
