ALUGEAR AERO Upgrade Kit for Shimano Dura-Ace R9100 (2x11)
An aero chainring and cover kit that brings ALUGEAR's machined 7075-T6 look to 11-speed Shimano Dura-Ace R9100 chainsets.
Highlights
Why we rate it
Breathes new life into 11-speed
Gives a Dura-Ace R9100 crank the modern aero chainring look without replacing the whole chainset.
Integrated aero cover
The supplied cover hides the joint between rings and crank arm for a smoother, cleaner drive side.
Three proven ratios
Choose 50-34, 52-36 or 54-40 to suit anything from hilly sportives to flat-out time trials.
Wide colour choice
Five ring colours and ten cover colours, selected independently, let you match your frame or go bold.
Broad chain compatibility
Works with 10- and 11-speed Shimano, SRAM and KMC chains.
