## Description

This 14 tooth sprocket is designed to clamp onto an 8mm REX™ shaft and integrate with 8mm pitch (05B) chain. Its two-piece clamping mechanism is a robust, non-marring solution for fastening to a shaft.

Beyond its clamping function’s excellent performance in high-torque applications, the overall sprocket is also balanced for rapid rotation in high-speed applications. The steel construction provides excellent strength and wear resistance, making it suitable for heavy-duty applications. A single hole on the goBILDA® 16mm square pattern runs through the sprocket to allow access to M4 screws that would otherwise be difficult to reach.

The clamping protrusion matches the 8mm thickness of standard Sonic Hubs. This makes sprocket-to-sprocket alignment straight and simple when pairing with a larger sprocket mounted to a Sonic Hub! You can also install this sprocket against a bearing, as its built-in shim prevents contact with a bearing’s outer race.
