Colson Series 1 Hub, Press Fit, 3/8 Plain Bore, Clamp Hub

Usually ships in 1-3 business days
These hubs were specially designed to mount the 7/8 wide Series 1 Colson Wheels and provide one of the most durable methods of mounting them.

The hubs are designed for an interference fit into the wheel and feature integrated cleats that cut into the wheel bore. The interference fit combined with the cleats provide excellent pull-out resistance and torque transfer.

The hubs are installed by pressing them into the unmodified bore of the wheel. We recommend using a 3-5 ton arbor press or a large bench vise to install the hubs. We DO NOT recommend hammering the hubs in. You can select to have hubs installed in the wheels when ordered together. This is available as an option on the appropriate wheel products.

With a suitably large press, the hubs can be pressed out and reused in other wheels. Please note the process of removing the hub will usually destroy the wheel bore making the wheel unusable.
