Proto Catalyst Gripper Wheels

The Proto Catalyst Gripper wheels are built for smooth, reliable performance across both street and park riding. Made from durable PU and paired with a solid 6061 T6 aluminium core, they’re designed to handle heavy use while keeping a fast, consistent roll.

Each wheel comes pre-installed with bearings and spacers, so they’re ready to ride straight out of the box.
The core graphic is a throwback to Proto’s Catalyst video from 2010, keeping things clean while nodding to the brand’s roots.
