    Shimano RS685 11 speed hyd. drop bar shifters

    Does anyone know if these Drop bar disc brake / 11 spd. shifters can be used with the 11 speed XTR cassette and rear derailleur? Want to do a monster cross type build with 1x11 gearing and prefer Shimano to SRAM.

    No...they have different pull ratios.
    But, with a long cage Ultgra derailleur and a Wolftooth link, you should be able to use a xtr 40t cassette

    Thanks for the answer. I was afraid that was going to be the case. The Wolftooth link might be the answer...

    Depending on where your frame/ hanger puts the derailleur pivot,,,,you may be able to just use the Ultegra.
    I have a GT Grade with a 11 speed long cage and just stuck a wheel with a 10 speed cassette with a 42 t cog. I was able to screw in the b screw enough to get it to shift on and off the 42 and it looks like plenty of chain wrap. I wasn't able to ride it, of course

    Get the R785 and XTR Di2 single ring set up. That works together, albeit expensive. Can't run a front derailleur or it will make the RD not work but I think that looks like a really cool set up.

    I'd really like to have a clutch RD on my "road" bike that has the shimano road hydros (GT grade). Sucks that a mountain RD doesn't work.
