1309 Series Sonic Hub (6mm D-Bore)

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!

The innovative Sonic Hub design is perfectly balanced. It will not introduce vibrations into your build, even in high-speed applications. The 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.

The body of this hub is aluminum, and the pinch bolts are zinc-plated steel. Aluminum has an excellent strength-to-weight ratio, allowing this hub to be both light and strong.
