These cogs have a tall tooth profile that is essential for preventing chain skip from the extra torque a singlespeed drivetrain encounters. In addition to being a stellar SS cog, the cog base width (where it contacts the freehub body) is 4.35mm, so you can stack a few of them up and use a 9-speed shifter for a simplified multi-speed drivetrain. This width also prevents it from ruining the freehub body as a result of digging grooves into it like skinny stamped cogs have a tendency to do. Surly cogs are machined from SCM415 CroMoly steel, then heat-treated for toughness and chrome-plated for surface hardening and enhanced chain lubricity. Our cogs will work with 6-9-speed 3\/32\" chains, although we recommend the inherently updated quality of an 8 or 9 speed chain. They are also available in every increment from 13-22t, so you can select that perfect gear.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"http:\/\/surlybikes.com\/info_hole\/spew\/spew_single-speed_gearing_101\" target=\"_blank\"\u003eSinglespeed Gearing 101\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"http:\/\/surlybikes.com\/info_hole\/spew\/spew_single-speed_drivetrains\" target=\"_blank\"\u003eSinglespeed Drivetrains\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"http:\/\/surlybikes.com\/\/uploads\/downloads\/Surly_Cassette_Cog_Instructions.pdf\" target=\"_blank\"\u003eCassette Cog Instructions\u003c\/a\u003e\u003c\/p\u003e","brand":"Surly","offers":[{"title":"3\/32 13T","offer_id":40496519413959,"sku":"SRLC1FW2071","price":75.0,"currency_code":"NZD","in_stock":false},{"title":"3\/32 14T","offer_id":40496519446727,"sku":"SRLC1FW2072","price":75.0,"currency_code":"NZD","in_stock":false},{"title":"3\/32 15T","offer_id":40496519479495,"sku":"SRLC1FW2073","price":75.0,"currency_code":"NZD","in_stock":false},{"title":"3\/32 16T","offer_id":40496519512263,"sku":"SRLC1FW2074","price":63.0,"currency_code":"NZD","in_stock":false},{"title":"3\/32 17T","offer_id":40496519545031,"sku":"SRLC1FW2075","price":93.0,"currency_code":"NZD","in_stock":true},{"title":"3\/32 18T","offer_id":40496519610567,"sku":"SRLC1FW2076","price":75.0,"currency_code":"NZD","in_stock":false},{"title":"3\/32 19T","offer_id":40496519643335,"sku":"SRLC1FW2077","price":75.0,"currency_code":"NZD","in_stock":false},{"title":"3\/32 20T","offer_id":40496519676103,"sku":"SRLC1FW2078","price":100.0,"currency_code":"NZD","in_stock":false},{"title":"3\/32 21T","offer_id":40496519708871,"sku":"SRLC1FW2079","price":75.0,"currency_code":"NZD","in_stock":false},{"title":"3\/32 22T","offer_id":40496519741639,"sku":"SRLC1FW2080","price":75.0,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0537\/1074\/9895\/products\/3ed5873286c15dcf9af33e1e0c03a8b8.jpg?v=1626674415"},{"product_id":"surly-track-cog","title":"Surly Track Cog","description":"\u003cp\u003e\u003cspan\u003eOur track cogs are designed for fixed gear applications and are compatible with most English, Italian and Japanese hubs, including the Surly New Track Hubs.
