Shimano Dura-Ace-Level Precision
The FC-9000 36T-MB inner chainring is built to Shimano Dura-Ace standards, with precise tooth shaping designed to support fast, clean and reliable shifting between the 36T inner ring and matching 52T outer ring.
MB Chainring Pairing
The MB designation identifies the chainring as part of Shimano’s 52-36T semi-compact pairing. This is important because Shimano front shifting depends on correctly matched chainring profiles, ramp timing and tooth positions.
110mm Asymmetric 4-Arm Fitment
Shimano’s FC-9000 crankset uses an asymmetric 4-arm spider design. This layout places material where pedalling forces are highest, improving stiffness while allowing one crank platform to support multiple chainring combinations.
Aluminium Alloy Construction
The chainring uses lightweight aluminium alloy construction to balance low weight, stiffness and precise machining. This helps maintain efficient power transfer and responsive shift performance.
Restores Front Shift Quality
A worn inner chainring can cause slow front shifts, noisy running, poor chain pickup, chain drop or reduced drivetrain efficiency. Replacing it with the correct genuine Shimano 36T-MB ring helps restore the original performance of the FC-9000 crankset.
Genuine Shimano Replacement Advantage
Using the correct Shimano replacement chainring helps maintain the original shift quality, appearance and drivetrain compatibility of the Dura-Ace FC-9000 system. This is especially important on high-end 11-speed road bikes where front shifting precision matters.
