Melvin bolts to the derailleur hanger and uses two pulleys to manage chain tension and chain wrap, helping keep the drivetrain quiet and consistent. It also includes chainline adjustment via spacers at the mounting pivot, and the pulleys have side to side float to help handle small chainline variances.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eFeatures |\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMounts to a standard rear derailleur hanger\u003c\/li\u003e\n\u003cli\u003eTwo pulley design provides 20 teeth of chain wrap\u003c\/li\u003e\n\u003cli\u003eChainline adjustment using pivot spacers\u003c\/li\u003e\n\u003cli\u003ePulleys use sealed bearings and allow 1 8 inch single speed chains\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eSpecs |\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"width: 100.087%; height: 195.938px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.83%; height: 19.5938px;\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"width: 65.9071%; height: 19.5938px;\"\u003eMelvin Chain Tensioner\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.83%; height: 19.5938px;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"width: 65.9071%; height: 19.5938px;\"\u003ePaul Components\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.83%; height: 19.5938px;\"\u003eProduct Type\u003c\/td\u003e\n\u003ctd style=\"width: 65.9071%; height: 19.5938px;\"\u003eChain Tensioner\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.83%; height: 19.5938px;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"width: 65.9071%; height: 19.5938px;\"\u003e6061 Aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.83%; height: 19.5938px;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"width: 65.9071%; height: 19.5938px;\"\u003e108 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.83%; height: 19.5938px;\"\u003eFinish\u003c\/td\u003e\n\u003ctd style=\"width: 65.9071%; height: 19.5938px;\"\u003eAnodized\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.83%; height: 19.5938px;\"\u003eMounting\u003c\/td\u003e\n\u003ctd style=\"width: 65.9071%; height: 19.5938px;\"\u003eRear derailleur hanger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.83%; height: 19.5938px;\"\u003eChainline Range\u003c\/td\u003e\n\u003ctd style=\"width: 65.9071%; height: 19.5938px;\"\u003e44 to 52 mm (\u003cmeta charset=\"utf-8\"\u003efor 135 142 rear spacing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.83%; height: 19.5938px;\"\u003eLargest Rear Cog\u003c\/td\u003e\n\u003ctd style=\"width: 65.9071%; height: 19.5938px;\"\u003e20 teeth\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5938px;\"\u003e\n\u003ctd style=\"width: 33.83%; height: 19.5938px;\"\u003eChain Wrap\u003c\/td\u003e\n\u003ctd style=\"width: 65.9071%; height: 19.5938px;\"\u003e20 teeth\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.83%;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"width: 65.9071%;\"\u003eAfter 8\/12\/25 most 6-12 speed chains.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.83%;\"\u003eUse\u003c\/td\u003e\n\u003ctd style=\"width: 65.9071%;\"\u003eSingle speed conversions, vertical dropout frames\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Paul Components","offers":[{"title":"Black","offer_id":50449185439991,"sku":"200BLACK","price":240.0,"currency_code":"CAD","in_stock":false},{"title":"Silver","offer_id":50449185472759,"sku":"210000025429","price":240.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0023\/1505\/9318\/files\/paul-components-melvin-chain-tensioner-black-dismount-bike-shop-toronto-canada.png?v=1769642123","url":"https:\/\/dismountbikeshop.com\/products\/paul-components-melvin-chain-tensioner","provider":"Dismount Bike Shop","version":"1.0","type":"link"}
