The SRAM Red E1 Chain is the lightest and strongest chain SRAM has ever produced. Featuring Flattop technology, this chain is narrower for quieter operation and enhanced strength and durability. The Hard Chrome plated inner link plates and rollers reduce wear and extend the chain’s lifespan, while the HollowPin construction boosts overall strength and efficiency. Super-light outer plates with a cut-out design contribute to its exceptional lightness, making it 13 grams lighter than the previous Red chain. The SRAM Red E1 Chain combines advanced technology and materials to deliver unmatched performance and reliability on every ride.
