SRAM PC-XX1 Eagle 12スピード チェーン

About SRAM PC-XX1 Eagle 12 Speed Chain - Gold
It might look normal from the outside, but the engineering inside this incredible chain design that 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.

Features
Groundbreaking chain design and technology

The Eagle chain has been completely re-engineered, and is produced with new manufacturing technology.

Eagle Power Lock chain connector with FLOWLINK 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

Technology
PowerLock: SRAM chain engineers developed PowerLock as a tool free, sure, and consistent way to connect their 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.

Hard Chrome: The SRAM HARD CHROME chain has four times the elongation (wear) resistance to their 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.

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.

Eagle: Eagle technology represents SRAM's newest 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 520%, which is equal to 2x11 drivetrains.

Flowlink: Ultra-smooth chain inner-plates are completely devoid of square edges, resulting in a chain that engages the cassette and chainring with far less friction, for quieter performance and better wear life. The design allows a narrower overall profile that can withstand greater angles, and also allows for a flatter outer-plate, which means more consistent chain riveting and enhanced overall strength.

About SRAM
Founded in 1987, SRAM (an acronym of the 3 founders names, Scott, Ray and Sam) is a privately owned bicycle component manufacturer located in Chicago. They're known for developing many of the inovative technologies used in bikes today including ETAP wireless electric shifting, Grip Shift, dedicated single chain ring drivetrains, narrow wide chainrings and more. Sram also own bicycle component brands Rockshox, Quarq, Zipp and Truvativ.
