Our Socket Drive interface system has been in use on our Flatware cranks since their inception, and it was only a matter of time before the system was adapted into our Thunderbolt cranks. The time has come.
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. The interface is solid and reliable, so we are now offer the Killington sprocket to match.
