Paragon Machine Works is going out of their way to meet the new direct mount rear derailleur standards for Shimano drivetrains. These new rear derailleur direct mount hangers are available to fit most of Shimano’s new models. The direct mount hanger is strong, stiffer, and designed to mount the derailleur where Shimano intended for it (about 25mm back) to allow their Shadow system to work and performing wheel changes easier.
Paragon Machine Works now offers many combinations for Shimano Direct Mount rear derailleurs, SLX, XT XTR, ZEE and Saint. What’s the big deal? Is this another standard that’s going to make your frame obsolete? If you have PMW sliding dropouts, rocker dropouts, PolyDrops, or any PMW dropout with a replaceable hanger, the answer is no. A replacement insert or hanger will update your frame to use the latest Shimano derailleurs. So, why bother? What does a DM derailleur do for you? Basically, the main derailleur pivot has been moved about 25 millimeters to the rear of its conventional location, and the hanger itself is stronger than a conventional hanger. The rearward position is important for Shimano’s Shadow geometry to work, and also gets the derailleur out of the way during wheel changes. If you’ve ever wrestled with your QR skewer stuck in the derailleur cage or chain, you’ll appreciate this feature. The stronger hanger is an asset if you’re a rider that expects the most from your equipment. Increased strength means a rigid mount for the derailleur, contributing to snappier shifting. Shimano’s DM derailleurs will work with either 10 mm or 12 mm axle systems, depending on the the insert or hanger used. Finally, with the broad selection of options, a rider doesn’t need to use DM. If there’s a hub/axle/derailleur combination you like, PMW can accommodate it. Updates can be made at any time as components or personal preference change.
