SRAM - PC X01 Eagle Chain - 12SPD - 126 links

It might look normal from the outside, but the engineering inside this incredible chain design makes possible a gear range previously found only in 2-chainring drivetrains. And it's also the biggest contributor to the Eagle™ drivetrain's ultra-smooth, precise, durable and quiet performance.

The Eagle™ chain's links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear on chainrings and cassette cogs. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength. HARD CHROME™ technology extends the chain's optimal performance life.

Features: 

• Groundbreaking chain design and technology.
• The Eagle™ chain has been completely re-engineered, and is produced with new manufacturing technology.
• Eagle™ PowerLock® chain connector with FLOW LINK™ technology provides better chain-guiding and increased longevity.
• The Eagle™ chain is the quietest, strongest and most wear-resistant chain in the world.
• Unique features and design also provide significantly improved wear resistance on Eagle™ cassettes and rings.
• HollowPin™ Riveting

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.

POWERLOCK: 
SRAM chain engineers developed PowerLock as a tool free, sure, and consistent way to connect our chains. While PL does not require special tools for install, the especially tight tolerances of 10- and 11-speed drivetrains mandate that each PowerLock is good for a one-time application only.

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. Accept no imitation.
