Standard Series Non O-Ring Chain

A dependable, budget-friendly drive chain for riders who want solid performance without paying for sealed-chain features. The DID Standard Series Non O-Ring Chain is a high-quality solid roller chain made from special alloy steel and designed for machines that were originally equipped with a non O-ring (non-seal) chain. It comes factory pre-stretched to help reduce initial slack and maintain more consistent chain adjustment over time.
