Hi all, I am trying to convert an older (2009) Specialized Epic to a commuter / gravel bike, and I am wondering if anyone has ever adapted drop bars and shifters to a Shimano XTR MTB groupset with hydraulic disk brakes. It is currently a 3x9. I might also consider swapping over to a 2x, or a 1x if possible. I am having a hard time finding what cassettes will fit on the existing 135 QR hub. Has anyone else attempted any of this silliness ??
