Trek 107 Direct Mount 3DP Titanium Derailleur Hanger

Silca Trek 107 Direct Mount 3DP Titanium Derailleur Hanger is a precision upgrade and replacement hanger designed to increase rear-derailleur stability on compatible Trek frames using the Trek 107 interface. Built from 3D printed titanium, it targets the two failure points of many stock hangers—flex and impact damage—helping riders maintain more consistent shifting alignment while still protecting the frame in a crash.

• 3D Printed Titanium Construction - engineered for high strength and stiffness to reduce hanger deflection that can compromise shifting accuracy
• High-Stiffness Upgrade - claimed up to 12x stiffer than a stock aluminum hanger for better derailleur control, especially under load
• Direct Mount Interface - replaces the Shimano B-Link for a cleaner, more rigid derailleur mounting solution; relevant as newer Shimano XTR and XT groups no longer include a B-Link
• Frame-Saving Fracture Notch - designed to be sacrificial in severe impacts, concentrating failure at the hanger to help protect the frame and derailleur
• Low Weight - claimed 2–10 g lighter than the stock hanger, trimming weight without giving up durability
