Chain Specifications?

[LylaDella]

Chain specifications, transmission chains are divided into Series A and Series B. Series A conforms to the size specifications of American chains, while Series B conforms to the size specifications of European chains. The difference between the two types of chains is minimal. 2. Chain specification model table The rollers and pins of Series A chains have a certain proportion, while the main dimensions of Series B parts do not have an obvious proportion to the pitch. Except for the 12B specification, which is lower than Series A, all other specifications of Series B are equivalent to Series A products. 3. Chain specification model comparison table, defined by the application of the chain. Structurally, chains are divided into roller chains and bushing chains. Based on their usage on motorcycles, they can be categorized into those used inside the engine and those used outside the engine. Chains used inside the engine are mostly of the bushing chain structure, while chains used outside the engine are drive chains for the rear wheel, mostly using roller chains.
