Shimano XT FC-M780 / FC-T780 / FC-T781 10-speed Chainring

The Shimano XT 10-speed Chainring for the FC-M780 crank

This Shimano 10-speed XT chainring is compatible with the FC-M780 crank, but also with the FC-T780 or FC-T781 touring crank, depending on the version. With its 104 mm or 64 mm bolt circle diameter, it can be used for various 3-speed gradations. The SG-X tooth profile ensures smooth and quiet shifting in the Dyna-Sys 10-speed drivetrain. The chainrings are designed to work optimally with the other front drivetrain components (HyperDrive).

Note to Type Designation:

The type designation (one or two characters) helps identify the compatibility of various chainrings with other chainrings. Because the larger chainrings have specially-formed teeth and upward shifting assistance, only particular smaller chainrings will match to ensure proper shifting performance. An XY chainring should only be combined with another XY chainring. This applies to all other types as well.
