Although the Shimano CN-HG700 chain is a spare part, it has a number of advantages. For example, it is SIL-TEC surface-treated. This is a modern coating process that improves system performance through the use of embedded fluorine particles. As a result, the treated products run smoother and wear less. Secondly, the chain has an asymmetrical design. The left side is optimized for changing gears at the front, the right side for changing gears at the rear. In addition, the specially shaped plates optimize the engagement on the sprocket and lead to even smoother gear changes - even under load. Fast and good shifting is guaranteed with the Shimano CN-HG700 chain, but unfortunately you have to pedal fast and well yourself.
