The JetStream Pro Asymmetric Oversize Pulley Wheel Set (AOPW) enhances drivetrain efficiency with oversized pulley wheels and nano-coated ceramic bearings, ensuring smooth chain operation. Its patented design simplifies the upgrade to larger pulley wheels without changing the derailleur cage, maintaining original chain length even in extreme gear ratios. AOPW reduces the complexity, time, and cost of upgrades, boosting riding performance.
