# 25 Chain is an American standard size that is built to ANSI B29.1 standards. In fact, this is the smallest ANSI chain size that is produced. This miniature chain is commonly referred to as 1/4" pitch roller chain, which comes from the pin to pin measurement. 25 Chain is one of the most widely used chain sizes out of the 14 available ANSI standard chains.
Nitro ANSI #25 Chains are built using the latest technology and made from quality materials that undergo special processes to enhance the strength. We're dedicated on continually researching and finding ways to improve our already high-quality roller chains.
