About OSPW

Oversized pulley wheel systems (OSPW) reduce drivetrain friction and improve shifting performance. These aftermarket jockey wheel upgrades feature larger ceramic or steel bearings and lightweight alloy or carbon cages. Find budget-friendly OSPW systems compatible with Shimano, SRAM, and Campagnolo derailleurs. Compare pulley sizes from 12T to 17T, bearing types, and cage materials. Whether for road racing, time trials, or simply smoother shifting, oversized pulley wheels offer measurable watt savings and enhanced drivetrain efficiency.
