Wolf Tooth Chainring: 38T XT8000 Cranksets with a 96 Asymmetrical BCD

Drop-Stop technology. On Wolf Tooth's patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction, Alternating wide/narrow tooth pattern also prevents chain derailment.
