Technology:

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™:
SRAM employs HollowPin™ construction on all of thier 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 chainrings 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™ chainrings 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.
