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.
The all-new SHIMANO DEORE M6100 rear derailleurs deliver advanced shifting performance with decreased tension in the low gear position. Larger 13T pulleys increase efficiency and chain management while compatibility with SHIMANO's new 12-speed
The GX Eagle Transmission (T-Type) chain is the strongest we have ever made. Specifically engineered to optimize Eagle Transmission, this all-new T-Type design features a unique flat top.
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.
