The 12mm REX™ Bore Hyper Hub is a heavy duty, balanced, clamping solution to fastening onto a 12mm REX™ Shaft. The dual pinch-bolts put a mega-hold on the shaft and the extended length of the hub offers excellent surface contact with the shaft. The REX™ profile matches a 12mm REX™ shaft so that a positive drive is created and there’s essentially no chance of slipping. As with all Hyper Couplers, this coupler is balanced so that it can be used in high-speed applications without introducing vibrations.
Made for 12mm REX™ Shafting
This hub allows you to mount components to a 12mm REX Shaft.
Part of a Large Ecosystem of Parts
The goBILDA® ecosystem has many parts that bolt directly to this hub. That includes wheels, gears, sprockets, track sprockets, timing pulleys, round belt pulleys, winch pulleys, control arms, and more!
High-Speed Design - Completely Balanced
The innovative Hyper Hub design is perfectly balanced. It will not introduce vibrations into your build, even in high-speed applications.
The generous amount of shaft contact paired with the positive drive provided by the REX profile allows this hub to be used in high-torque applications.
Will Not Get Stuck or Marr Shaft
Our Hyper Hub design (patents pending) holds incredibly tight to the shaft without damaging it. When it is time to disassemble, it readily releases its grip on the shaft.
This hub is machined for high-precision fitment.
Will Not Corrode or Rust
The body of this hub is aluminum, and the pinch bolts are zinc-plated steel.
Lightweight & Strong
Aluminum has an excellent strength-to-weight ratio, allowing this hub to be both light and strong.
