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\/span\u003e\u003c\/p\u003e\n\n\t\t\t\u003cp\u003e\u003cspan style=\"font-size:16px\"\u003e\u003ca href=\"http:\/\/surlybikes.com\/info_hole\/spew\/spew_single-speed_gearing_101\" target=\"_blank\"\u003eSinglespeed Gearing 101\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\t\t\t\u003cp\u003e\u003cspan style=\"font-size:16px\"\u003e\u003ca href=\"http:\/\/surlybikes.com\/info_hole\/spew\/spew_single-speed_drivetrains\" target=\"_blank\"\u003eSinglespeed Drivetrains\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\t\t\t\u003cp\u003e\u003cspan style=\"font-size:16px\"\u003e\u003ca href=\"http:\/\/surlybikes.com\/\/uploads\/downloads\/Surly_Cassette_Cog_Instructions.pdf\" target=\"_blank\"\u003eCassette Cog Instructions\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\t\t\t\u003c\/td\u003e\n\t\t\t\u003ctd style=\"width:40px\"\u003e \u003c\/td\u003e\n\t\t\t\u003ctd style=\"vertical-align:top\"\u003e\n\t\t\t\u003cp\u003e \u003c\/p\u003e\n\t\t\t\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\u003c\/tbody\u003e\n\u003c\/table\u003e\n","brand":"Surly","offers":[{"title":"Surly Single Splined Cassette Cog 13 Tooth 3 \/ 32","offer_id":45171394609302,"sku":"SRLC1FW2071","price":93.0,"currency_code":"NZD","in_stock":false},{"title":"Surly Single Splined Cassette Cog 14 Tooth 3 \/ 32","offer_id":45171394642070,"sku":"SRLC1FW2072","price":76.0,"currency_code":"NZD","in_stock":false},{"title":"Surly Single Splined Cassette Cog 15 Tooth 3 \/ 32","offer_id":45171394674838,"sku":"SRLC1FW2073","price":93.0,"currency_code":"NZD","in_stock":false},{"title":"Surly Single Splined Cassette Cog 16 Tooth 3 \/ 32","offer_id":45171394707606,"sku":"SRLC1FW2074","price":93.0,"currency_code":"NZD","in_stock":false},{"title":"Surly Single Splined Cassette Cog 17 Tooth 3 \/ 32","offer_id":45171394740374,"sku":"SRLC1FW2075","price":93.0,"currency_code":"NZD","in_stock":false},{"title":"Surly Single Splined Cassette Cog 18 Tooth 3 \/ 32","offer_id":45171394773142,"sku":"SRLC1FW2076","price":100.0,"currency_code":"NZD","in_stock":false},{"title":"Surly Single Splined Cassette Cog 19 Tooth 3 \/ 32","offer_id":45171394805910,"sku":"SRLC1FW2077","price":93.0,"currency_code":"NZD","in_stock":false},{"title":"Surly Single Splined Cassette Cog 20 Tooth 3 \/ 32","offer_id":45171394838678,"sku":"SRLC1FW2078","price":100.0,"currency_code":"NZD","in_stock":true},{"title":"Surly Single Splined Cassette Cog 21 Tooth 3 \/ 32","offer_id":45171394871446,"sku":"SRLC1FW2079","price":100.0,"currency_code":"NZD","in_stock":false},{"title":"Surly Single Splined Cassette Cog 22 Tooth 3 \/ 32","offer_id":45171394904214,"sku":"SRLC1FW2080","price":73.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/7845\/1350\/files\/3ed5873286c15dcf9af33e1e0c03a8b8.jpg?v=1751534244","url":"https:\/\/cycleworx.co.nz\/products\/surly-single-cog","provider":"CycleWorx NZ","version":"1.0","type":"link"}
