SRAM Chain Hollow Pins PC1091 10 Speed

The most recent 1091 chains have much more beveled outer plates to allow a better change and a quieter ride. The hardened chrome bush ensures longer chain life. The structure with hollow bushes ensures strength and lightness. PowerLock connection joint. HollowPin: We use HollowPin construction technology on all the best SRAM products in the PowerChains line. HollowPin sets standards of robustness in maintaining the plate, efficiency of the front and rear gearshift and low weight, unattainable in chain applications with solid bushings. PowerLock: SRAM chain designers have developed PowerLock technology as a safe and consistent method to connect our 10-speed chains without the use of tools. While PowerLock requires no special tools for installation, the tight tolerances of 10-speed transmissions require that each PowerLock element only be applicable once.
