FEATURES
NO REFILLS NECESSARY!
No need to keep buying expensive CO2 cartridges or anything of that sort!
Our hubs will have lower maintenance requirements than suspension forks and definitely less than full suspension bikes.
ENTIRELY MECHANICAL – BATTERYLESS
We’re in love with all things mechanical, but more to the point: why depend on temperamental electronics that enjoy failing when you least expect?
UNLIMITED NUMBER OF PRESSURE REGULATION CYCLES
Adjust tire pressure like you command your shifting gears, as many times as you like. Think about it: What would be the use of gears if you could only shift ~ 100 times per ride?
FULLY OPERATIONAL THROUGH ANY WEATHER CONDITIONS
What’s the use of gear if it stops working when it’s “too” cold?
We know the frustration of freezing hydraulic lines, failing suspension seals and battery capacity going to zero.
COMPATIBLE WITH YOUR BIKE AND PREFERRED TIRES
Our best guess is that you already have a bike you love… From day one we designed our hubs to be backwards compatible with the popular Fat Bike axle “standards”, 6-hole disc brakes, and 10 or 11 cassettes.
ULTIMATE TUBELESS-READY ENHANCEMENT
We all love Tubeless-Ready… once you’ve tried it there’s no going back!
Yet… it’s not always ideal. Experiencing a burp in a tight fast-rolling turn is a frightening experience and requires you to stop immediately

PERFORMANCE
Tire pressure regulation:
- Min pressure user defined at start of each ride.
- Pressure regulation range: 15 psi (1 Bar) typical
- Max pressure: Min Pressure + Range (obviously)
- Regulation cycles: unlimited
- Regulation steps: end-user modulable
Pressure regulation energy requirements:
- Pressure hold: None (obviously)
- Inflation: Zero/None/Nada (yep, that’s the magic)
- Deflation: 45Watts @ 9.5 mph ( 15 Km/h) typical
Performance gains due to Pressure Optimization on standard MTB tires :
- Rider saves 15 Watts typical
Weight
- WhiteCrow Hub ~ 350 grs over typical hub (of which ~150 grs is non-rotating mass)
- In-tire chamber ~ 200 grs (yet enables mounting thin-walled & light tires, which results in reduced rolling resistance for the similar overall weight)
Over 130 Freewheel engagement points
- Less than 2.70 deg !
- Engineered for unique sound
Construction and wheel strength
- Main hub body parts in USA-made 7075-T6 aluminum hard-anodized
- Central hub body in Carbon Fiber, multi-directional pre-preg
- Enduro bearings
- 32 spokes in an “ultra-wide triangle” enable extra-strong wheel construction in with light-weight short spokes
