Product Details & Benefits
Chaser direct-mount rear derailleur hanger, precision-machined from TC4 titanium with full CNC construction. It reduces weight from the ~35.5 g OEM piece to ~15.8 g (screws excluded) while maintaining stiffness and alignment, delivering crisp shifting. 0.1 mm shims are included to eliminate axial play between the hanger and derailleur. After installation or replacement, re-align and fine-tune shifting following Shimano's procedures.
