1313 Series Hyper Hub (8mm REX™ Bore)


The 8mm REX™ bore Hyper Hub is a heavy-duty, balanced, clamping solution to fastening onto an 8mm 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 8mm REX shaft so that a positive drive is created and 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 16mm square pattern, the 1313 Series of Hyper Hubs also has shouldered arms which provide four additional holes on the 32mm square pattern. This provides even more support for those larger builds. The shoulders have a 32mm diameter allowing the hub to nestle into parts which have a 32mm hole for a compact, low moment-arm setup


Made for 8mm REX Shafting
This hub allows you to mount components to an 8mm REX shaft. A "REX" shaft is part Round and part Hex. An 8mm REX shaft is 7mm flat-to-flat, like 7mm hex shafts. The difference is, that the tips are precision ground to an 8mm diameter allowing it to fit in an 8mm bearing. The bore of this hub has enough clearance in the corners to accept most 7mm hex shafts.

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 sprocketstiming pulleys, round belt pulleyswinch 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.

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 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.
