## Description

The 12mm REX™ bore Hyper Hub is a heavy-duty, balanced, clamping solution for 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 for fierce positive drive in which there’s essentially no chance of slipping. As with all Hyper Hubs, this hub is balanced so that it can be used in high-speed applications without introducing vibrations.

In addition to the standard threaded holes on the goBILDA® 16mm square pattern, the 1313 Series of Hyper Hub also has shouldered arms which provide four additional holes on the goBILDA® 32mm square pattern. This provides even more support for larger builds. The shoulders' 32mm diameter allows the hub to nestle into parts which have a 32mm hole for a compact, low moment-arm setup. Additionally, a built-in shim provides for contact with a bearing without binding against the bearing’s outer race.

### Features

**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](https://core-electronics.com.au/gobilda/motion/wheels-tires.html), [gears](https://core-electronics.com.au/gobilda/motion/gears.html), [sprockets](https://core-electronics.com.au/gobilda/motion/sprockets-chain.html), [track sprockets](https://core-electronics.com.au/gobilda/motion/tracks.html), [timing pulleys](https://core-electronics.com.au/gobilda/motion/timing-belts-pulleys.html), [round belt pulleys](https://core-electronics.com.au/gobilda/motion/round-belts-pulleys.html), [winch pulleys](https://core-electronics.com.au/gobilda/motion/cable-pulleys.html), [control arms](https://core-electronics.com.au/gobilda/motion/hub-mount-push-arms.html), 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.

**High-Torque Design**
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](https://core-electronics.com.au/gobilda/motion/hubs/shop-by-style/hyper-hubs-16mm-pattern.html) 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.

**Precisely Machined**
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.
