Aerodynamics Evolved. Performance Simplified.
Designed for pure racing intent, the JetstreamPRO AOPW-AERO represents the next evolution of TRiPEAK’s oversized pulley system, now combining aerodynamic efficiency with effortless usability.

Before AOPW, upgrading to oversized pulley wheels was often complex and time-consuming. With the AOPW-AERO, the process is streamlined. Using only a standard hex wrench, riders can quickly upgrade to the 18T system, no complicated setup required＊, and experience smoother, faster drivetrain performance from the first ride.

＊Chain length and B-tension should still be checked after installation.

Aerodynamic Flow-Cover Design

A newly engineered lower pulley cover features a sealed flat outer surface with an integrated inner guide plate, optimizing airflow through the drivetrain.
Compared to standard AOPW systems, drag is reduced by approximately 10-15%, delivering real aerodynamic gains where it matters most.

Enhanced Drivetrain Efficiency

At the core of the system, the oversized 18T tension pulley significantly improves chain dynamics.
Compared to traditional 11T pulleys, it reduces chain articulation angles, minimizes friction, and enhances overall pedaling smoothness and stability, especially under load.

Effortless Upgrade, Immediate Performance

The patented asymmetric frame design allows the 18T pulley to integrate seamlessly into the original derailleur cage with minimal modification.
The result: a fast, intuitive installation and immediate improvement in drivetrain efficiency.

Engineered Stability & Durability

Molded Composite Pulley Construction ensures zero-tolerance bearing integration, increasing durability and reducing noise

Hollow Frame Design allows for larger bearings, improving rotational stability and protecting against external interference

Narrow-Wide Tooth Profile enhances chain engagement for smoother and more secure operation

JetstreamPRO Ceramic Bearing System

Built around TRiPEAK’s Rotation Optimized Ceramic Technology, every component is engineered to reduce friction and maximize speed:

G3-grade ceramic balls for ultra-low rolling resistance

Nano-coated races (NC Bearings) reducing friction to as low as 0.03

Supra LV lubricant for high-speed, low-viscosity performance

Zero Contact Seals for optimal protection without added resistance

Modular Compatibility

One system, multiple platforms, fully compatible with:

- Shimano R92XX

- Shimano R81XX

- SRAM Red E1 / Force E1

The result: a fully integrated aerodynamic pulley system that is faster, smoother, and easier to install, designed for riders who demand performance without compromise.
