It took us some time to add a single speed model to the Sanderson line up as we couldn't decide which of the currently available EBB designs to use as they all seemed to have inherent problems. We decided to design our own with the aim of eliminating the usual creaking and loosening associated with all other current designs. The SSS ebb system utilises a threaded shell and EBB to achieve the maximum contact area and two aluminium lock rings to keep it all securely in place. After extensive testing not a single creak or loose EBB has been found.
