The Shimano Dura-Ace FC-R9100 chainrings are genuine replacements for worn or damaged rings on FC-R9100 and FC-R9100-P cranksets. Rings wear out long before the crank arms do, so fitting fresh ones restores the crisp, quiet shifting the groupset was built around.

The outer rings use HOLLOWGLIDE construction, a hollow-forged design that adds rigidity and saves weight at the same time. Taking the flex out of the outer ring is what you notice on the road: the chain climbs cleanly and predictably, staying precise even when you shift under high load.

Tooth profiles are developed to run only with 11-speed chains, giving closer contact between chain and ring and more efficient power transfer. Rings are sold individually and the inner and outer are matched pairings, so a 53T-MW outer runs with a 39T-MW inner, and a 52T-MT outer with a 36T-MT inner. Check which pairing your chainset uses before ordering.
