A worn chain causes poor shifting performance and reduces the service life of sprockets and chainrings by wearing down the teeth. Regular checking for chain wear and a timely chain replacement prevent costly premature replacement. 11 and 12 speed chains should not be stretched more than 0.5%. When using aluminium and titanium cassettes, the tolerance is 0.75%, whereas chains on steel and singlespeed sprockets should be replaced at 1% wear at the latest. For precise measurement, the Birzman chain wear indicator tool clearly shows the chain stretch. A practical chain hook on the other side of the tool is a welcome aid to hold the chain when opening and closing chain links.\u003c\/span\u003e\u003c\/p\u003e","brand":"My Store","offers":[{"title":"STD","offer_id":42144293126179,"sku":"BM10-ST-CC-01","price":850.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/2043\/2675\/files\/5_6df56655-d989-456f-b610-102157fd87e2.webp?v=1775208238","url":"https:\/\/oyeathlete.com\/products\/birzman-chain-wear-indicator-i-1-12-speed","provider":"Oyeathlete","version":"1.0","type":"link"}
