This sealed cable system provides the quickest and smoothest shifting ever. Very nice. It has been raining all week and my shift quality has not changed one bit.
I only had one problem with the installation: The outer sheath is larger diameter than standard Shimano sheath, which means it was torn up quite a bit when forced through the fixed diameter cable guides on my Cannondale Raven. Other than the fact that my installation does not look as clean as I would have liked due to the cosmetic damage, the shifting is the best it has ever been.
