Chains

The strongest system is a chain with no weak links. Eagle chain links have a smooth radius with no sharp edges or chamfers, which yield a significant reduction in noise, friction, and wear. This design also allows for a flatter plate for more consistent chain riveting and greater overall strength. It's also the biggest contributor to the ultra-smooth, precise, durable, and quiet performance found in the 10-50T cassette and X-SYNC 2 chainrings. Additionally, installation is made easy with a dedicated 12-speed Eagle quick link. - Groundbreaking new chain design and technology - The Eagle chain has been completely re-engineered and is produced with new manufacturing technology. - All-new 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

It might look normal from the outside, but the engineering inside this incredible new chain design is anything but normal and it 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, and a Titanium Nitride coating on the Gold and Black models decreases corrosion and further reduces friction.

KMC X12 chains feature a double X bridge shape for fast and smooth shifting. - Compatible with SRAM 12-speed systems - Double X bridge shape with inner and outer plate chamfering for smooth and fast shifting - Mushroom riveted pins for the highest pin power and allows shifting under heavy loads - 1/2 x 11/128 - 126 Links

- X9SL: superlight chain for use with 9-speed, 252g - X9.93: upgraded version of the Z-9000 chain stretchproof, super-narrow chain for use with 9-speed - Pink Lady chains are a limited edition with 15% of sales going directly to the Pink Ribbon Foundation - Width = 11/128-inch

For smooth shifting and a quiet drivetrain, pick up Campagnolo's Chorus 11-speed chain. It's unidirectional for unparalleled function and features lightweight hollow pins as well as an anti-friction treatment for shifting perfection. It also boasts excellent wear and flex resistance.
