The 6mm round bore Sonic Hub can be used on 6mm round shafting, 6mm OD standoffs and spacers and even 6mm D-shaft. There are some use cases where you need to clamp onto something other than a d-shaft, or, maybe you want to clamp onto a d-shaft while retaining the freedom to clock your hub independent of the location of the flat on the shaft. As with all Sonic Hubs, this hub is balanced and possesses two pinch bolts to maximize the clamping force while maintaining a slim profile.
Made for 6mm Shafting
This hub allows you to mount components to a 6mm diameter 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 Sonic Hub design is perfectly balanced. It will not introduce vibrations into your build, even in high-speed applications.
Will Not Get Stuck or Marr Shaft
Our patented Sonic Hub design 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.
