The Pinarello Disc Brake Frame Dropout (DISC-THRUAXLE-LEFTIN) is a precision-engineered replacement or upgrade dropout designed specifically for Pinarello frames with disc brake thru-axle systems. This component plays a critical role in aligning the rear wheel, transmitting braking forces, and maintaining the precise geometry that Pinarello bikes are known for. Whether you’re servicing a frame, rebuilding a wheelset, or ensuring your bike’s structural interfaces are in top condition, this dropout delivers the fit and strength demanded by high-performance road and gravel riding.

Manufactured to exacting tolerances, the LEFTIN dropout ensures accurate alignment of the rear thru-axle, keeping the wheel secure and properly centered within the frame. This is essential for consistent handling, optimal drivetrain alignment, and reliable disc brake engagement. The design integrates seamlessly with Pinarello’s disc-specific architecture, supporting the forces generated by modern high-modulus braking while preserving clearance and stiffness.

Built from robust materials chosen for durability and fatigue resistance, the dropout stands up to the repeated stresses of riding, transport, and wheel installation. Its precise machining and surface finishes help ensure easy installation and long-term service life, whether in a professional workshop or home garage environment. This component is ideal for mechanics replacing a worn or damaged dropout or builders assembling frames for race, training, or endurance use.... Read More
