WILIER DROPOUT CENTO1 HYBRID DX

The Wilier Cento1 Hybrid DX Rear Dropout / Derailleur Hanger is a highly specific, proprietary frame replacement component engineered explicitly for the drive-side (DX) rear dropouts of Wilier's lightweight e-road and gravel lines. 

Because the Cento1 Hybrid features an integrated Mahle ebikemotion X35 rear hub motor its rear dropouts do not use standard bicycle geometry; instead, they feature structural flat slots and locking faces tailored to hold the motor axle's high torque.
