Socket Drive™ System

Watch as Jim Bauer walks you through the installation process for our Socket Drive™ Thunderbolt cranks and corresponding sprocket.

For those who might be unfamiliar… In a nutshell, the Socket Drive™ system is a 9 sided interface which eliminates the need for a sprocket bolt. The sprocket itself is machined so there is no need for a sprocket insert of any kind. The two work great together. In addition to OUR OWN sprocket offerings, other BMX brands have released Socket Drive™ compatible sprockets as well.
