  • 148mm x 12mm TA
  • Weighs in at a competitive 282.3g
  • 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

Recently had a wheel built by SpokeX and couldn't be happier. Thanks Hunter for the custom build. Looking forward to other transactions. New local shop which I am happy to support. Looking forward to be able to online order

Hunter was awesome! Great customers service. Bought my 1st Yeti from SpokeX. The derailleur needed some tuning and it was done the next day. The service  they provide for Yeti owners is great. As many of you know, there's a break-in period where parts need to settle in and they provide  a free follow-up service to retune the bike. Shop is pretty cool too. They have chairs you can spin on while waiting.
