It can be used to check 12 to 21 tooth sprockets. Procedure: The  chain is put on the sprocket and the tool placed with its round end between two  teeth on the upper sprocket side. The last chain link is moved away from the  sprocket and a force of 100 N or 10 kg is applied to the tool in the direction  of sprocket rotation.\u003c\/li\u003e     \u003cli\u003eNow the last chain link is moved towards the sprocket. If it skips easily to  the cog the sprocket is in a good condition and will function flawlessly even  with a new chain. However, if the last chain link gets stuck on the tip of the  neighbouring tooth or if we have to force it to skip on the cog, the sprocket is  worn out and should be replaced. In case the chain falls off the clog when  applying force, the sprocket is heavily worn out and a replacement is overdue.\u003c\/li\u003e     \u003cli\u003echrome plated\u003c\/li\u003e \u003c\/ul\u003e","brand":"Unior","offers":[{"title":"Default Title","offer_id":44972449464390,"sku":"619717","price":35.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0728\/0328\/7110\/files\/88296_1.jpg?v=1777686500","url":"https:\/\/bicyclehero.com\/products\/unior-bike-sprocket-wear-indicator-tool-1658","provider":"BicycleHero","version":"1.0","type":"link"}
