XTR chainrings

[gtr1]

I have found out that Shimano don't make a 39t chainring for 2x10. Does anyone know of a compatible chainring that may do a 39t to fit XTR ?

 

Reason is my hard tail has SRAM with a 39t, but the dual cane with XTR and a 38t. Trying to keep the same, without changing SRAM to 38t.

What's the BCD of the XTR?

 

You don't necessarily need to use an XTR/Shimano chainring

It looks like 104mm. They are M980 cranks

Then you just need to find any 39t 104mm BCD chainring.

Have a look on Chain Reaction - search for 'Blackspire', click on 'Chainrings'. I know they have 38, 39 and 40 rings to fit the Shimano XTR M985. Not sure if these fit the M980, or what the BCD implications are. Email them if it's not clear.

The XTR 985s have an 88bcd
