The redesigned cage plate of Aero Wing ensures stable support for the 18T oversized pulley, providing a smooth operational space. It incorporates a blend of alloy and carbon plates, striking an ideal balance between lightweight construction and stability.

All new aerodynamic cover wraps around the wind-facing side of the derailleur cage, offering superior Aerodynamic efficiency. With a detachable design, installation is a breeze – just remove one screw. No need to replace the entire derailleur cage; riders can decide which cover to install it based on look or function.

The Hollow Frame design of the pulley allows for a significant increase in bearing size, providing superior rotational performance and stable support for the 18T oversized pulley. The hollow fixed frame design substantially reduces the impact of any external object intrusion, ensuring consistent and reliable rotational performance at all times. Plus, it looks great!

The 18T tension pulley design results in smoother chain movement. Compared to the original 11T
derailleur pulleys,it reduces chain deflection angles and minimizes rotational resistance. Simultaneously adopting large-diameter bearings significantly enhances the smoothness and stability of the pedal performance.

Unlike traditional press-fit bearing pulleys, Tripeak's injection-molded pulley fully encases its bearing, ensuring a perfect zero-tolerance fit between pulley body and bearing. The composite material of the pulley body enhances its wear resistance, resulting in quieter and more efficient operation. Compared to traditional aluminum pulleys, it significantly extends the lifespan of both pulley and chain.

The Narrow-wide Tooth Design allows the pulley to better engage with the chain, significantly improving operational stability.

Jetstream Pro Series stands for Rotation Optimized Ceramic Technologies. Because it takes more than just ceramic balls to minimize friction and gain watts. It´s about the composition of race, seal, lubricant and balls. Jetstream Pro Series delivers the right composition for the purpose. The JetStream Pro series offers exceptional efficiency and durability, backed by a reassuring four-year warranty for users.

G3-grade perfectly round ceramic balls create lower rotational resistance, allowing your power better to convert to speed.

NC Race Bearings have a Nano coating on outer & inner races, This dry film can minimize the coefficient of friction to as low as 0.03 dynamic, and 0.07 for static. The Nano Coating overcomes or reduces mechanical lubrication problems improving performance and extending service life >300%

Supra LV is a special Low Viscosity  lubricant for the ceramic Pulley Bearings. It offers high flow characteristics for a fast and smooth operating environment. Easy to lubricate in maintenance without removing the seal of the bearing.

ZERO Contact Seal, a non-contact bearing seal, provides complete coverage without increasing rotational resistance, striking the optimal balance between efficiency and protection.
