Designed to be the strongest chain with no weak links. The SRAM PCXX1 Chain utilises a smooth radius with no sharp edges or chamfers, yielding a significant reduction in noise, friction and wear. The chain is designed with a flatter plate, meaning there is more consistent chain riveting and overall greater strength. The 10-50 tooth cassette and X-SYNC 2 chainrings provide ultra-smooth, precise, durable and silent performance for the ultimate smooth and powerful ride. The SRAM PCXX1 Chain’s installation is made easy thanks to a dedicated 12-speed Eagle quick link.
