Chainring teeth wear down gradually enough that most riders don't notice the degradation until shift quality falls off a cliff — the chain starts skipping under power, front shifts get hesitant, and no amount of cable tension or trim adjustment brings it back. If your Force AXS crankset has been logging serious miles, the outer ring is usually where wear shows up first. SRAM's Force eTap AXS 2x12-speed drivetrain is built around the X-Range design principle, where the difference between outer and inner chainrings is a uniform 13 teeth across every size combination , and this D1-generation outer ring is the direct replacement to restore that shift quality.

Both outer and inner aluminum chainrings share a 107mm bolt circle diameter, with the pick-up points on the outer ring hidden behind a cover plate for a clean look. The 4-bolt 107 BCD interface uses SRAM's CR-FRC-107-D1 platform , so this ring drops onto any Force AXS 2x12 crankset using the D1 spider — it is not compatible with the newer thread-mount E1 chainrings or with the 94mm BCD Wide cranksets. The precision-machined tooth profiles are optimized for wear and paired specifically to their matching inner ring for chain pick-up during upshifts , which is why SRAM sells outer and inner rings as size-matched pairs rather than interchangeable parts.

The 46T outer is designed to run with a 33T inner for a 46/33 combination, and the 48T outer pairs with a 35T inner for 48/35. If you're replacing only the outer ring on a worn crankset, keep the same tooth count as your original setup — mixing sizes outside SRAM's published pairings puts the front derailleur cage outside its designed capacity and can throw off the chain pick-up geometry between rings. When you're replacing an outer ring on a 4-bolt Force AXS crankset, the inner ring has usually taken on some wear too, and swapping both at once with a fresh chain is the cleaner path to getting shift performance all the way back to new.
