I don't want my 11 speed chain connector breaking and wedging the chain into my carbon frame so I am using the reusable Wipperman Connex. Unlike 10 speed an lower, other 11 speed connectors require a tool to remove them and lock them into place. The ridge that the connector slides along gets worn from this. With the Wipperman, you can easily take it off or put on a by hand - the unique curved locking mechanism holds it in place without the need of a tight-fitting locking mechanism that the others use.


They are more expensive, but to me it is $20 for a connector vs. $2000 for a new frame. Just my 2c.
