The cage is damped against that motion — enough to hold the chain settled, not so much that shifts get slow or the chain fights you climbing the cassette.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRange limit:\u003c\/strong\u003e 36T maximum, 28T minimum.

That's what eliminates trim — the cage is already at the right angle whether you're in the 10 or the 36.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAuto trim.\u003c\/strong\u003e On top of the Yaw geometry, the derailleur makes its own micro-adjustments as you move across the rear cassette.

Your frame needs a braze-on tab on the seat tube. If your frame doesn't have one, you'll need a separate clamp adapter in 31.8mm or 34.9mm, sold separately.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e2. 45mm chainline, 2x only.\u003c\/strong\u003e It's built for a standard road chainline and 46\/33T, 48\/35T, or 50\/37T chainring combinations. It will not work with a Wide 47.5mm chainline crankset — that needs a Wide-specific front derailleur — and it obviously won't work on a 1x build.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e3. Chainstay angle between 61 and 66 degrees.\u003c\/strong\u003e Most road frames fall inside this. Some gravel and long-chainstay frames don't. Your frame manufacturer publishes it.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eAXS app\u003c\/h4\u003e\n\n\u003cp\u003ePair both derailleurs to the SRAM AXS app and you can check battery levels on each, reassign what every control does, get service reminders, and push firmware updates.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSequential shifting\u003c\/strong\u003e is the feature worth setting up on a 2x build. Turn it on and the system manages the front derailleur for you — you keep pressing the same paddle, and it decides when to move the chain across the front and compensate at the rear to keep the gear progression smooth. It makes a 2x drivetrain feel like a 1x with more gears in it.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eBatteries\u003c\/h4\u003e\n\n\u003cp\u003e\u003cstrong\u003eYou need two AXS batteries and a charger. Neither is included.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThey're interchangeable front to rear, which is genuinely useful: if the rear derailleur dies mid-ride, pull the front battery and swap it back. You lose front shifting and finish the ride with a working rear.\u003c\/p\u003e\n\n\u003cp\u003eThe shift levers are a separate system — they run CR2032 coin cells that last years, not rides.\u003c\/p\u003e\n\n\u003cp\u003eCarrying a spare battery in a jersey pocket is cheap insurance. It swaps in about five seconds with no tools.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eMixing tiers\u003c\/h4\u003e\n\n\u003cp\u003eEvery AXS component speaks the same wireless protocol, so you can mix freely. These derailleurs work behind RED or Force levers. A RED cassette runs fine on a Rival drivetrain.\u003c\/p\u003e\n\n\u003cp\u003eRival is where most people should spend the least in an AXS build — the shifting is functionally identical to the tiers above, and the difference is materials and grams. Put the savings into wheels.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eYou will need a SRAM Flattop chain\u003c\/h4\u003e\n\n\u003cp\u003eSRAM's 12-speed road drivetrains use \u003cstrong\u003eFlattop\u003c\/strong\u003e chains, a different design from standard 12-speed chains.
