{"product_id":"park-tool-21s-cc-3-2-chain-wear-indicator","title":"Chain wear indicator CC-3.2","description":"\u003cp class=\"MsoNormal\"\u003eA worn bicycle chain can cause poor shifting and in time can even cause excessive wear to the derailleur and rear cogs, causing a much more expensive problem. That's why bike component manufacturers recommend chain replacement at regular wear intervals. The Park Tool CC-3.2 is a go\/no-go gauge designed to accurately indicate when a chain reaches 0.5% and 0.75% wear (or \"stretch\"), the points at which most chain manufacturers suggest replacement. The CC-3.2 is long, accurate, and features permanent measurement markings. The CC-3.2 works on most derailleur chains* from 5 to 12-speed.\u003c\/p\u003e","brand":"Park Tool","offers":[{"title":"Default Title","offer_id":48618896261376,"sku":"210000103730","price":16.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/9302\/3922\/files\/park-tool-chain-wear-indicator-cc-3-2-chain-wear-indicator-1232869433.jpg?v=1776552849","url":"https:\/\/www.squirejohns.com\/products\/park-tool-21s-cc-3-2-chain-wear-indicator","provider":"Squire John's","version":"1.0","type":"link"}
