I had starting looking for a new rear derailleur when I stumbled upon the Cannondale website. They spec their Jekyll MX as having a xt shadow + with sram x7 shifters? Thats not possible right? Is there some way this could work? I have always read no mix and match for rear derailleurs.

Maybe just a misprint?
