Description
Replacement nylon chain guide block for your Micro Sprint chain guide plate. The guide block is the wear surface that keeps the chain tracking where it should instead of climbing the sprocket or slapping the frame.
Nylon is used here because it wears rather than eating your chain. That means it is designed to be consumed – a guide block worn thin stops guiding, and you find out when the chain jumps.
Check it whenever you have the chain off. Cheap enough to keep a spare in the trailer. Fits standard Micro Sprint chain guide plates. In stock in Fresno, CA.
