The XX1 chain comes from a long line of tough, light-weight chains from SRAM. When every bit of torque counts, you can count on it to deliver.
Hard Chrome - The SRAM Hard Chrome chain has four times the elongation (wear) resistance to our other chains. This is due to the new finishing process on the inner links and rollers. Push pin strength and ultimate strength are equivalent to our current chains. The Hard Chrome chain lasts longer and is just as strong.
HollowPin - We employ HollowPin construction on all SRAM top of the line PowerChains. HP yields plate retention strength, front and rear shifting efficiency, and low weight benchmarks unreachable in solid pin chain applications.
X-Sync - SRAM X-Sync 1x chain rings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain.
