Chains

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

Beyond an incremental improvement. The Flattop technology of the SRAM Force chain creates a lighter, quieter, stronger chain. Ride far, long and fast—this chain can go the distance. - Flattop technology allows for a narrower chain with quieter operation and increased strength and durability - Hard Chrome plated inner and outer plates for faster and more precise shifts

It might look normal from the outside, but the engineering inside this incredible 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.

The Shimano CN-M9100 features an extended inner link plate that connects seamlessly with chainring teeth for highly efficient drivetrain performance. Its design offers a reduction in natural vibrations normally caused by the inner and outer chain plates rolling onto the chainring. It provides better chain engagement, stronger retention, and smoother pedaling. - Enhancements to shifting performance - Easy connect - Non-reusable - Smoother driving even over bumpy terrain - Compatible with Shimano Quick Link SM-CN910-12 - This chain meets durability requirements for E-MTB applications
