Thanks to the new Dura-Ace R9100 crankset's ingenious spider design, both inner and outer chainrings share a common BCD. This means that the lighter, stiffer Dura-Ace FC-R9100 Chainrings are one-size-fits-all, as long as you're working with a new Dura-Ace R9100 or R9100-P crankset you can switch out chainrings to your heart's content.

The Shimano Dura-Ace FC-R9100 11-Speed Chainrings is available in a variety of sizes for inner and outer ring applications.

Inner Ring Sizes:

  • 34 tooth.
  • 36 tooth.
  • 39 tooth.
  • 42 tooth.

Outer Ring Sizes:

  • 50 tooth.
  • 52 tooth.

Tried and True
by Matt

Not much to say, tried and true chainrings. Converted back to 2x for my gravel rig, too much tarmac between gravel sections where I live, so went with 50x34 which was the sweet spot on my previous gravel bike. Lives us to Dura Ace standards, can�t go wrong.
