{"product_id":"surly-track-cog-1-8-x-18t-silver","title":"Surly Track Cog 1\/8'' X 18t Silver","description":"Surly track cogs are threaded the same as a BMX freewheel (1.375 x 24 tpi right-hand threads). This means that they will fit on single-speed rear hubs as well as BMX freewheel hubs but this application is not recommended. Track cogs are meant to work on track hubs only.\u003cli\u003e415 hardened chromoly steel\u003c\/li\u003e\u003cli\u003e1.375\" x 24 tpi\u003c\/li\u003e\u003cli\u003ePhoto for color and material reference only\u003ctable border=\"1\" cellpadding=\"5\" cellspacing=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eTooth Count\u003c\/td\u003e\n\u003ctd\u003e18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003e1\/8''\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e","brand":"Gio's Outdoors","offers":[{"title":"Default Title","offer_id":54008026300700,"sku":"SUR2572751R","price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/5051\/0364\/files\/4853b55f795d62814674f3ca29c9d93db5d85485.jpg?v=1774733849","url":"https:\/\/pearlcitycycle.com\/products\/surly-track-cog-1-8-x-18t-silver","provider":"Pearl City Cycle","version":"1.0","type":"link"}
