{"product_id":"cassette-wrench-x-range","title":"Cassette Wrench X Range","description":"\u003cp\u003eSRAM's X-Range gearing dropped the small cog to 10 teeth across AXS road, AXS XPLR gravel, and Eagle Transmission MTB cassettes. The 10-tooth cog is what lets X-Range run a single-chainring drivetrain with the range of a 2×; but it's also too small for a chain whip or a conventional cassette wrench to engage cleanly. The X Range cassette wrench is the version sized for the 10-tooth small cog, with three steel pins that land in the cog's narrow tooth gaps and a 350 mm handle for the leverage to back the lockring out.\u003c\/p\u003e\n\u003cp\u003eWorking on X-Range cassettes without the right holder is the slow way to round teeth. A chain whip wrapped around a 10-tooth cog sits on three or four teeth at most; under the torque the lockring takes to break free, the chain walks, the cog teeth roll, and the chain ends up pulled into the cassette body. The pin-engagement design avoids the walking; the three pins seat in three distinct tooth valleys, the load distributes evenly, and the cog teeth stay flat.\u003c\/p\u003e\n\u003cp\u003eThe wrench is specifically for X-Range. The pin spacing on this version is tighter than the standard 11\/12t or 13\/14t wrench; trying to use the X Range wrench on a conventional 11- or 12-tooth small cog won't seat the pins right, and trying to use the 11\/12t version on a 10-tooth cog won't seat at all. The three Unior cassette wrenches don't overlap; they tile the small-cog range from 10 teeth to 14 teeth.\u003c\/p\u003e\n\u003ch2\u003eWhat counts as X-Range\u003c\/h2\u003e\n\u003cp\u003eSRAM's X-Range cassettes include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRed AXS, Force AXS, Rival AXS, Apex AXS road\u003c\/strong\u003e; 10-26, 10-28, 10-30, 10-33, 10-36 cassettes (the leading \"10\" is the small cog)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAXS XPLR gravel\u003c\/strong\u003e; 10-44, 10-46, 10-52 cassettes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEagle Transmission MTB\u003c\/strong\u003e; XX SL, XX, X0, GX, S1000 12-speed T-Type cassettes (10-52 standard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEagle AXS\u003c\/strong\u003e; 10-50, 10-52 cassettes (pre-Transmission)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor SRAM 11- and 12-speed cassettes with an 11-tooth small cog (older Eagle, GX 11-speed, road 1× pre-AXS), the \u003ca href=\"\/products\/cassette-wrench\"\u003e11\/12t version\u003c\/a\u003e is the right pick.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.sram.com\/en\/life\/stories\/x-range-gearing\"\u003eSRAM X-Range gearing reference\u003c\/a\u003e covers the rationale for the 10-tooth design; narrower side-to-side chain geometry, larger jumps between cogs, wider total range from one chainring.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSRAM AXS road cassettes (10-tooth small cog): Red, Force, Rival, Apex\u003c\/li\u003e\n\u003cli\u003eSRAM AXS XPLR gravel cassettes\u003c\/li\u003e\n\u003cli\u003eSRAM Eagle Transmission (T-Type) MTB cassettes\u003c\/li\u003e\n\u003cli\u003eSRAM Eagle AXS 12-speed MTB cassettes\u003c\/li\u003e\n\u003cli\u003eNot for SRAM HG or XD\/XDR cassettes with 11- or 12-tooth small cogs (use \u003ca href=\"\/products\/cassette-wrench\"\u003e11\/12t\u003c\/a\u003e)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThree pin engagement on the 10-tooth small cog\u003c\/li\u003e\n\u003cli\u003eNotched pins for slip resistance under load\u003c\/li\u003e\n\u003cli\u003e350 mm handle for full lockring break-free leverage\u003c\/li\u003e\n\u003cli\u003eX-Range-specific pin spacing\u003c\/li\u003e\n\u003cli\u003eArticle number: 1670\/2BI-US (X-Range variant)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eBuilt in Zreče, Slovenia\u003c\/h2\u003e\n\u003cp\u003eUnior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. SRAM's X-Range gearing was a real drivetrain change; the 10-tooth small cog needs a cassette wrench sized to it, not a workaround on an 11\/12t tool. The X Range cassette wrench is the third member of the Unior cassette-wrench family, sized to match the cog size SRAM moved the field to.\u003c\/p\u003e\n\u003ch2\u003ePro tip from our mechanics\u003c\/h2\u003e\n\u003cp\u003eMost workshops doing AXS service ended up buying an X-Range wrench within a season of the cassette pattern shipping in volume; the cog-rounding risk on a chain-whip workflow with 10-tooth small cogs convinced people fast. If your shop only sees AXS occasionally, the wrench is a one-purchase fix for every X-Range cassette swap from now on. For workshops handling Eagle Transmission specifically, this wrench is the cassette-side tool that pairs with the \u003ca href=\"\/products\/1660-2dp-us-multispeed-chainwhip\"\u003eMultispeed Chainwhip 1660\/2DP-US\u003c\/a\u003e (which also covers Flattop) when the chain whip is preferred on the larger cogs.

If your cassette's smallest cog has 11 or 12 teeth you want the 11\/12t version instead, and 13 or 14 teeth the 13\/14t version.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy won't a normal cassette wrench or chain whip work on a 10-tooth cog?\u003c\/strong\u003e A 10-tooth cog is too small for a chain whip or a conventional cassette wrench to engage cleanly - there simply is not enough tooth surface to grip safely under lockring torque. The X Range version's three steel pins are sized to land in the 10-tooth cog's narrow tooth gaps, so the hold is positive before you lean on the 350 mm handle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the tool in the technique photo show a 12 marking?\u003c\/strong\u003e The in-use photo shows the 11\/12t body of the same wrench family demonstrating the technique. The X Range version you are buying here is the same forged wrench with its pins sized for the 10-tooth cog - the head is etched 10 AXS X-RANGE.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I still use a chain whip on X-Range cassettes?\u003c\/strong\u003e On the larger cogs, yes - for Eagle Transmission work some mechanics prefer a chain whip there, and the Multispeed Chainwhip 1660\/2DP-US (which also covers Flattop chain) is the one to pair with this wrench. On the 10-tooth small cog itself, the pin wrench is the tool that engages cleanly.\u003c\/p\u003e","brand":"Unior","offers":[{"title":"X-Range","offer_id":44140824068140,"sku":"629061","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/5786\/5260\/files\/1670_2bi-axs-us_23629061_23image_1024.jpg?v=1784909560","url":"https:\/\/uniorusa.com\/products\/cassette-wrench-x-range","provider":"Unior USA","version":"1.0","type":"link"}
