More and more people are switching to single ring drivetrains and the Race Face Direct Mount Cinch Narrow Wide Single Chain Ring enables the switch to be made without using a chain guide. This ring is designed to prevent chain drops by persistently keeping the chain engaged through the use of "Narrow-Wide" teeth profiling. Every other tooth is shaped like a regular, non-shifting tooth, but the other teeth are thicker, with additional "spines" on either side of the tooth. This combination fits into the chain's different-sized links, and practically eliminates the chance of chain drop. The Direct Mount attaches as part of the Race Face Cinch system (using common Park BBT-22 bottom bracket tool), allowing to switch between DM rings/spiders with ease.
