Shimano Deore XT FC-M780 104mm BCD 4 Arm Outer Chainring – 42T-AE

This outer chainring can only be used with Shimano Deore XT FC-M780 10 speed triple chainsets with a 42-32-24T set up.

If the correct outer chainring is unavailable you can also use the chainring from the following chainsets:

– Shimano XTR FC-M980
– Shimano Deore XT FC-M770-10
– Shimano SLX FC-M660-10

These are a “B” match which indicates that the parts are usable, but differ in materials, appearance, finish & size etc.

Genuine Shimano replacement part.
