Shimano Ultegra CN-6701 10s

The latest chains from DURA-ACE, ULTEGRA, and 105 feature a unique new asymmetric design.

When installing, the direction of rotation must be observed. The specially shaped plates optimize engagement on the sprocket and lead to even smoother gear shifts, even under load.

To save weight, these chains have cutouts in the inner plates and hollow pins (the latter only for DURA-ACE).

• Super narrow 10-speed HG chain (directional)
• Newly shaped inner and outer plates with predetermined direction improve contact with the teeth and allow shifting even under high load.
• The left side is optimized for rear HG (Hyperglide) shifting and ensures fast and precise gear changes. The right side is optimized for chainring changes.
