Lance Roberts Posted January 20, 2016 Posted January 20, 2016 Hi everyone, I'm looking at upgrading my bike to the new XT M8000 2x11 and was wondering if it would work if I got the new M8000 shifter and kept my existing front derailuer, which was for 2x10 configuration? I'm ok with the rear derailuer already, just the front that I'm wondering about. The only thing I can think of is the width of the M8025 derailleur guide that might be suited better for the 11 speed chain. Anyone have any experience in doing this? Thanks!
Lance Roberts Posted January 21, 2016 Author Posted January 21, 2016 Anyone with some input regarding this question?
Skinnyone Posted January 21, 2016 Posted January 21, 2016 The new M8000 shifter may or may not have a different pull ratio that may cause issues with the existing FD. perhaps better to stick with the old shifter as well...

Wont fit.Will probably have to bite the bullet and get the M8025 derailuer.Thanks.
JCA12 Posted January 21, 2016 Posted January 21, 2016 are there no adapters available? Think I saw one (but they may be from the M8000 shifters to the older brakes) somewhere.

Bizkit031 Posted January 21, 2016 Posted January 21, 2016 Will have a look around. As far as I know there is none yet.
Robbow Posted January 21, 2016 Posted January 21, 2016 I run a 2x10 XT FD with an XTR shifter with no drama on my M8000 2x11 setup. This is using the new M8000 26/36 crank with matching rear shifter, RD and brakes. I dont have any issues with the shifting of it. Granted it didnt mount to the brake lever, and the XTR shifter is on it's own bracket.

Eddie Stafford Posted January 21, 2016 Posted January 21, 2016 Evans cycles in the UK now have the new XT 11 speed shifters in the I-spec B version. Sorry I misread your question. On the Evans webside http://www.evanscycles.com/products/shimano/xt-m8000-i-spec-b-11-speed-shifters-ec116590#features it says - Compatibility: For use with Dyna-Sys11 11-speed only So according to them, the M8000 shifter will not work with the previous derailleur. Not sure if it is just marketing. The next question will be - if the M8000 front derailleur will work with the M785 2 speed crank.
Spoke101 Posted January 21, 2016 Posted January 21, 2016 M8000 2x shifter will work with a 2x10 front derailuer.
