We took the lightest and most durable chain we’ve ever made and made it lighter. With no compromises. Our HollowPin construction is lighter and stronger than a solid pin, and cutouts in the outer and inner plates drop 13g from the previous generation. This results in a lighter, faster, stronger and more durable chain. FEATURES: Flattop technology enables a narrower chain with quieter operation and increased strength and durability Hard Chrome plated inner link plates and rollers for reduced wear and prolonged life 12/13spd HollowPin construction for increased strength and efficiency Super-light outer and inner plates with cut-out design 13g lighter than previous RED chain Rainbow colorway available in all sizes
