Oversize Ceramic Pulley Kit for Shimano GRX

Description

The Tripeak Oversize Pulley Kit makes upgrading simple and accessible. With the AOPW system, riders can swap to the larger 18T pulley using only a common hex wrench. No complicated adjustments are required—just install and ride with immediate gains in smoothness and speed.

18T Tension Pulley for Smoother Shifts: Compared to standard 11T pulleys, the 18T oversized design reduces chain deflection and rotational resistance. This results in smoother chain movement, improved stability and enhanced pedaling efficiency, especially on demanding rides.

Hollow Frame for Strength and Performance: The hollow frame design accommodates larger bearings, significantly improving rotational performance and providing stable support for the oversized pulley. It also reduces the impact of external object intrusion, ensuring consistent operation while adding a clean, sleek aesthetic.

Precision-Built Ceramic Bearings: Unlike press-fit pulley designs, Tripeak’s injection-molded pulley fully encases its ceramic bearing. This creates a perfect zero-tolerance fit, reducing wear and delivering quieter, more efficient operation while extending the lifespan of both the pulley and the chain.

Durable Composite Body: Crafted from a composite material, the pulley body is built for wear resistance and long-term performance. Compared to traditional aluminum pulleys, it offers better durability and reduced noise, making it an investment in smoother, quieter rides.

Narrow-Wide Tooth Engagement: With its narrow-wide tooth design, the pulley ensures secure chain engagement for improved stability. This feature minimizes chain drops and further enhances efficiency, making it a perfect upgrade for Shimano GRX 2X riders who demand reliability and performance.

Tripeak’s patented asymmetric pulley frame allows for the increase in pulley size to 18 teeth while fitting seamlessly into the original derailleur cage with minimal modification.
