SHIMANO 36T-MB DURA-ACE Chainring

The Shimano DURA-ACE 36T-MB chainring is a replacement inner chainring designed for the Shimano FC-9000 2x11-speed road crankset. With its 36 teeth and 110 mm bolt circle diameter, it is used exclusively with a four-arm asymmetric spider and forms the MB combination with a 52-tooth outer chainring.

Its hollow forged aluminum construction helps reduce weight while maintaining a rigid structure. The tooth profile is optimized to support the operation of the Dura-Ace drivetrain and ensure smooth shifting in the 52/36 configuration.

This chainring is intended for road bikes and must be installed on a compatible FC-9000 crankset. It is not suitable for newer Shimano cranksets that use a similar four-arm mounting, but a different chainring geometry.
