Notre avis

This small Shimano Dura Ace FC-R9100 road bike chainring benefits from the brand's latest technologies for even greater efficiency on the road and to adapt your gear ratios to your riding style.

Fred B.

The Shimano Dura-Ace FC-R9100 small chainring is designed to be fitted to Shimano Dura-Ace FC-R9100 cranksets in the inner position. Variants that use this crankset, such as the R9150 and R9120 groupsets, are of course compatible. The Hollowglide hollow chainring gives the crankset greater stiffness whilst being lighter, and optimises the rider’s power transfer from the pedal to the drivetrain.

Shifting from one chainring to another is also optimised so that the chain switches in a quarter-turn from the large to the small chainring and vice versa. It is important to ensure compatibility for optimum efficiency.

Technical specifications

- Tooth count: 34 - 36 - 39

Warning: Shimano strictly recommends the following combinations: 50x34, 52x36, 53x39, 54x42 or 55x42; other combinations, such as 53x36 or 52x34, may cause the chain to skip or jam, or even damage the crankset which is not covered by the manufacturer’s warranty.

Installation in 5 minutes in place of my 36 teeth, changed at the same time as the large chainring. Just need to readjust the height of the front derailleur and it rolls. Very reasonable price. (Translated review)
