{"product_id":"north-shore-billet-variable-tooth-chainring-28t-standard-64-bcd-black","title":"North Shore Billet Variable Tooth Chainring: 28T, Standard 64 BCD, Black","description":"The NSB Variable Tooth Chainrings uses a 'Thin-Thick' variable tooth thickness mated with a standard chainring tooth profile to help retain the chain on the front ring during all types of riding.  By increasing the tooth thickness on half of the ring's teeth, the chain is given less room to move and virtually eliminates chain drop when running a single front chainring.\u003cbr\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e\n\u003c\/li\u003e\n\u003cli\u003eTooth Count: 28\u003c\/li\u003e\n\u003cli\u003eRing Position\/Type: Chain Retaining Single Ring\u003c\/li\u003e\n\u003cli\u003eDrivetrain Speeds: 10\u003c\/li\u003e\n\u003cli\u003eDrivetrain Speeds: 11\u003c\/li\u003e\n\u003cli\u003eChainring BCD: 64\u003c\/li\u003e\n\u003cli\u003eColor: Black\u003c\/li\u003e\n\u003cli\u003eDefined Color: Black\u003c\/li\u003e\n\u003cli\u003eMaterial: Aluminum\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"North Shore Billet","offers":[{"title":"Default Title","offer_id":43729166958746,"sku":"NSB CR2803-B","price":55.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0327\/4483\/3156\/products\/CR3661.jpg?v=1689179251","url":"https:\/\/velomine.com\/products\/north-shore-billet-variable-tooth-chainring-28t-standard-64-bcd-black","provider":"Velo Mine","version":"1.0","type":"link"}
