Shibata Dr Racing Hub / Clamp-Type 4mm (2) (R31S135)

Designed and manufactured in Japan with an emphasis on minimizing rotational runout, this high-precision aluminum wheel hub delivers exceptional accuracy and smooth wheel rotation.

The clamp-style mounting system securely locks the hub in place, preventing the axle pin from accidentally falling out during wheel changes. This makes wheel installation and removal quicker, easier, and far less frustrating.

Unlike conventional designs that support the wheel hub across a flat surface, this hub features a point-contact support design. This allows for improved response to road input, providing sharper handling and a more direct steering feel.
