Hi
So i just put a deposit down for a 2012 specialized stumpy fsr frame and looking at what parts i need for the build.

Planning on running full xt 2x10, already have shifters, 11-36 cassette and 38/24 chainset, and going to purchase a shadow+ mech and chain.

I'm a bit confused about what front mechi need, obviously double specific.

this is the spiel in the manual;

10-Speed front derailleurs
SRAM S3 DMD front derailleurs: No adapters necessary. Choose the derailleur
based on the desired chainring size.
Shimano DMD front derailleurs: Choose the derailleur based on the desired chainring
size.
„ XTR FD-M985-E2: 38/40t chainrings
„ XTR FD-M985-E: 40/42/44t chainrings (40t position will not work on models with
2nd generation DMD mount. For these bikes, use FD-M985-E2)

so any idea which xt mech i need, e-type, e2?
