SRAM PC-991 Cross Step Chain The 9 speed chain to end all 9 speed chains. The Cross Step gets reinforced pins for greater strength over the standard PC991, making it a great choice for powerful riders wanting reliability from their drivetrain. When servicing your bike, it's hard to go past SRAM Components for quality gear that's designed to last. A high-end bike is nothing without high-end components and even something as simple as a worn cassette can make the difference between mis-shifting or powering past your mate on that steep climb. Worn gear cables, a stretched chain and rough cassette teeth can all contribute to ghost shifting or dropping a chain, and are the key parts linking your pedal power to the wheel. Thankfully, SRAM offer a full range of quality chains & cassettes for every pricepoint, so you can ensure your gears are running smoothly and dependably. We won't get into the whole SRAM vs Shimano debate, though we will recommend sticking with the one brand for driveline components for optimum performance (eg; using SRAM cassettes with SRAM Chains). You will find that SRAM shifting is very positive and solid regardless of the conditions, and will give you many miles of dependable service.
From SRAM: "No weakest link. SRAM'S Power Chain features the PowerLock connecting link — the only secure toolless attachment device for a sub 6mm chain in todays market. The PC 991 Cross Step version1 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."
