Derailleur hangers are designed to fail. That sounds counterintuitive until you consider the alternative: a bent hanger means a trip to the shop, while a bent frame means a new bike. The Pinarello Disc Brake Frame Dropout serves as this sacrificial component on thru-axle disc brake framesets, integrating the derailleur mounting point into a replaceable aluminum piece that bolts to the frame's right rear triangle.

Pinarello's dropout system for disc brake bikes breaks the rear axle area into multiple replaceable sections. The right side includes both inner and outer pieces, with the inner section carrying the derailleur hanger threads and the direct mount interface for your rear derailleur. This is that inner piece—the one that actually holds the derailleur and takes the hit if something goes wrong during a crash, a bad shift into the spokes, or an encounter with trail debris.

The dropout fits Pinarello disc brake frames with 12mm thru-axle rear spacing, covering a wide range of models: Dogma F12 Disc, Dogma F Disc, Dogma X, Prince TiCR, Prince FX, Grevil, Gan Disc, Paris Disc, and Nytro among others. If your frame uses the modular dropout design with separate inner and outer pieces and runs disc brakes with thru-axles, this is likely the correct replacement. The CNC-machined aluminum construction matches the original equipment specification, and the black anodized finish keeps everything looking factory.... Read More
