  • High Precision Steel Bearings
  • Fully customizable drive system with multiple options:
    • 6×2 (6 pawls with 2 pawl engagement) driver that yields 1.7° (216 POE) engagement or our 6×3 (6 pawls with 3 pawl engagement) option that yields 2.5° (144 POE) engagement
    • Quiet or loud pawls. QUIET PAWLS ARE TEMPORARILY UNAVAILABLE DUE TO MATERIAL SUPPY ISSUES. THERE IS NO KNOWN AVAILABILITY DATE FOR THE QUIET OPTION AT THIS TIME. 
    • XD, HG or Microspline** driver.
  • Machined pockets in the drive chamber allow for 25x more oil than our competitors’ hubs – more oil dampens sound slightly but it also extends time between service intervals.
  • Fine pitch bearing preload adjustment allows for zero play and compensation for bearing wear.
  • Better flange angles eliminate (or drastically reduce) spoke contact with flange,  reduce lateral flange loading and create a stiffer and longer lasting wheel build.
  • Industry leading warranty: 10 years on hub shell and axle, 3 years on pawls, drive ring, and driver body.

Testimonials

Thanks again for the amazing service ! I cannot thank all the guys at SpokeX for building me a killer set of wheels. They were super easy do deal with and I would gladly support them again ! Super great experience and I think I will have to order another set for my DH bike !! You guys rock !

After having wheels backorder for nearly 5 months I canceled the order and ordered new wheels through SpokeX. My wheels arrived less than 2 weeks later just in time for my Bentonville trip. These guys earned my business for sure!

Dope shop, staff is on point .. Got some good info on wheels, hubs, etc. They even worked on the same wheel off my bike three times until they figured out it was the off brand valve I used that was causing the slow leak...replaced it with a Muc-Off and been rolling good since.
