Shimano Ultegra CN-6701 Bike Chain 10 Speed
The Shimano Ultegra CN-6701 10-speed road bicycle chain uses optimized plates for improved power transfer and shifting performance.
- Asymmetric design with redesigned inner/outer plates virtually eliminate chain suck and improve contact with the cassette sprockets for smoother, noiseless shifting under heavy loads- for double chainrings only
- Reshaped outer plate is perforated to reduce weight and chain suck
- Reshaped inner plate lessens drivetrain friction for smoother rear shifting
- Enhanced press-in construction offers stable shifting action
