Shimano ZEE 640B and XTR

[byrt]

Hi Everyone
I was wondering if any mechanic can give me some advise please, Im looking into upgrading my drivetrain/ gears from my MTB

At the moment I have a Shimano ZEE 640B brakes and levers. I was looking into upgrading the gear shifters to the XTR but there are two models.
Does anyone knows if the shimano 640 B brake levers are compatible with the Shimano XTR M9000 11 Speed Trigger Shifter Rear - I-Spec II??

Thanks

No....... iSpec II is not backward compatible. Just buy the bar mount version of the xtr lever.

XT & SLX 11 speed shifters come in I-Spec B versions.

They do indeed, but the OP was specifically asking about XTR, which does not have an I-Spec-B option.
