It's almost a paradigm shift: Shimano is now offering a chain lock for 11-speed chains. Until now, Shimano chains - with a few exceptions - always had to be riveted. And this procedure can only be carried out with a special tool or multi-tool.

With the chain lock, Shimano will ensure easier and tool-free repairs on the trail in future, provided the bike is fitted with an 11-speed drivetrain. One drop of bitterness remains: The SM-CN900-11 chain lock is only designed for one-time use - meaning it cannot be reused, according to Shimano.
