PC-991 Cross Step Chain

No weakest link. SRAM'S PowerChain features the PowerLock connecting link — the only secure toolless attachment device for a sub 6mm chain in todays market. The PC-991 Cross Step features a secondary riveting process that increases the push pin strength by over 25% compared to our standard riveting. It's a combination of strength, lighter weight and our legacy of smooth, positive and precise shifting that delivers true high performance. This is our strongest chain.
