Boost Rear Hub

Weighs in at a competitive 282.3g
Fully customizable drive system with multiple options:
- 6x2 (6 pawls with 2 pawl engagement) driver that yields 1.7° (216 POE) engagement or our 6x3 (6 pawls with 3 pawl engagement) option that yields 2.5° (144 POE) engagement
- Quiet or loud pawls.
- XD or HG driver.
Very low drag driver. Our new drive system with quiet pawls produces 68% less drag than the system we previously used. Our loud pawls produce 51% less.
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.
