Primary Driven Sprocket Shim — 1mm Thick Aluminum

Is your primary chain drive louder than you want? The Surron Light Bee frame varies over time and when you install a primary chain drive you may find that the alignment from the motor sprocket to the primary driven sprocket may be off.

This causes a lot of noise and premature wear on the sprockets and the chain. Bring those sprockets back into alignment with a DirtyBike primary driven sprocket shim.

Shims are 1mm thick aluminum and most bikes usually only need one shim. Shim fits between the driven sprocket and the jack shaft.
