Works with 12-speed road and 13-speed XPLR AXS.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eHard Chrome — the number that matters\u003c\/h4\u003e\n\n\u003cp\u003eSRAM's Hard Chrome finishing process on the inner links and rollers delivers \u003cstrong\u003efour times the elongation resistance\u003c\/strong\u003e of their standard chains. Push-pin strength and ultimate strength are unchanged.\u003c\/p\u003e\n\n\u003cp\u003eElongation is what people call chain stretch, and it's the thing that actually kills a drivetrain. As a chain wears, its pitch grows and it stops meshing correctly with the cog teeth — at which point it starts carving new profiles into your cassette and chainrings instead of sitting in the existing ones.\u003c\/p\u003e\n\n\u003cp\u003eA chain that resists elongation four times longer isn't just a chain that lasts longer. It's a cassette that lasts longer, and chainrings that last longer. On an AXS drivetrain where the cassette costs three times what the chain does, that's where the money actually is.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eWhat Flattop does\u003c\/h4\u003e\n\n\u003cp\u003eLook at the top edge of the outer plates — flat where a conventional chain rounds off.\u003c\/p\u003e\n\n\u003cp\u003eSRAM developed the shape to enable X-Range gearing. Running a 10-tooth small cog means the chain has to wrap a much tighter radius than an 11-tooth ever asked for, and it has to do it without the plates interfering with each other. Flattop makes the chain narrower to clear that, and puts material back where load concentrates so nothing is given up in strength.\u003c\/p\u003e\n\n\u003cp\u003eThe side effects turned out to be the selling points: a narrower chain runs quieter, and the reshaped plate profile is stronger and more durable than what it replaced.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eCutouts and solid pins\u003c\/h4\u003e\n\n\u003cp\u003eThe E1 revision adds machined cutouts through the outer plates — weight removed from the areas that aren't carrying load, which is the cheapest kind of grams to lose.\u003c\/p\u003e\n\n\u003cp\u003ePins stay solid rather than hollow. That's what keeps this chain fully e-bike approved: a motor puts sustained torque through a drivetrain that legs can't match, and the pin is where a chain fails first under that kind of load. Solid pins cost a few grams and buy a much higher fatigue ceiling.\u003c\/p\u003e\n\n\u003cp\u003eNickel plating on the outer plates handles corrosion, which matters if you ride in weather or wash your bike more than you lube it.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eOne chain, both drivetrains\u003c\/h4\u003e\n\n\u003cp\u003eThis chain covers SRAM's full drop-bar AXS range:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-speed road AXS\u003c\/strong\u003e — Rival, Force, and RED, 1x or 2x\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e13-speed XPLR AXS\u003c\/strong\u003e — the gravel groups running 10-46T cassettes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eIf you have a road bike and a gravel bike, that's one spare in the parts bin instead of two.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eWhat it won't work with\u003c\/h4\u003e\n\n\u003cp\u003eFlattop is its own standard.

If you're building a large gravel frame or you're unsure, measure your existing chain first — a chain that's two links short is a chain you can't use.\u003c\/p\u003e\n\n\u003cp\u003eFollow SRAM's chain length procedure for your specific drivetrain rather than eyeballing it. Getting it wrong affects shift quality and derailleur behavior in ways that are irritating to diagnose after the fact.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eAbout the PowerLock\u003c\/h4\u003e\n\n\u003cp\u003eA Flattop PowerLock connector is included.

If you pull the chain for cleaning or a repair, install a fresh one. They're a few dollars, and a spare in your saddle bag turns a broken chain into a ten-minute trailside fix.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eReplace it before it costs you a cassette\u003c\/h4\u003e\n\n\u003cp\u003eCheck chain wear with a gauge every few hundred miles. Catch elongation early and you replace a chain.
