The RED Chain
SRAM’s RED eTap AXS™ group features unique chain design that has been developed from the ground up. Flattop technology enables a narrower chain with quieter operation and increased strength and durability. Hard Chrome plated inner link plates and rollers provide reduced wear and prolonged life, while SRAM’s HollowPin construction brings increased strength and efficiency to the design. The result is a quieter and faster chain that allows for more space between the outer plates and the cogs on either side.
