This is the complete kit for the Big Dummy. Both Power and return chains are controlled by a their own TerraCycle idler. The power side chain has an aluminum cogged idler for better power transmission and noise reduction, the return chain has a industrial urethane bed for a silent running system that keeps chain swing to a minimum and keeps your frame from getting dinged everytime you hit a bump especially when coasting. The return chain is now much higher up thus giving you greater ground clearance and keeps your chain cleaner during winter time riding.

Each Idler has its own custom clamp on mount, stainless chainkeeper and all the installation hardware. It is an easy installation to have you back on the road very quickly with an improved chainline.
