The Pilo GH-D1373 is a precision-engineered, CNC-machined derailleur hanger designed specifically for Java bicycles. It serves as a high-quality upgrade over standard factory-installed hangers, providing a more stable and accurate interface for modern high-performance drivetrains.

Features

• Manufacturing: 100% CNC-machined from solid billet aluminum (not a cast or forged part).

• Material: 6061 T6511 aircraft-grade aluminum for the optimal balance of strength and weight.

• Finish: Hard black anodized coating for high resistance to corrosion and wear.

• Axle Type: Designed for 12mm Thru-Axle systems.

• Quality Standards: Manufactured in an ISO 9001 2015 certified facility.

• Hardware: Typically includes the required mounting fastener.

• Crisper Shifting: The increased stiffness of CNC-machined aluminum minimizes derailleur movement and "flex" under cable tension. This is especially beneficial for 11 and 12-speed systems where even minor misalignment can cause skipping.

• Enhanced Durability: Unlike cast hangers which can be brittle, the 6061 billet aluminum is more resilient. The hard-anodized finish is also significantly more durable than the paint or light anodizing found on original equipment.

• Frame Safety: The hanger is designed to act as a "mechanical fuse." While it is robust enough for high-torque shifting, it is engineered to bend or break during a heavy impact to protect the carbon fiber frame from structural damage.

Compatible models

• Java Siluro Series: Including Siluro 2, Siluro 3, and newer disc-brake iterations.

• Java Fuoco Series: Fits newer aero-road disc models.

• Java Vesuvio: Compatible with recent carbon-frame endurance models.

• Java J-Air: Fits high-performance road framesets utilizing this specific hanger profile.
