Wolf Tooth has been making their popular 
Drop-Stop chainrings for a few years now out of aluminum which makes for a light and stiff chainring and is great for XC riding but doesn't hold up all that well when you introduce logs and rocks into your ride. If you prefer durable vs lightweight 
Wolf Tooth now makes the 
Drop-Stop chainrings in 
416 Stainless Steel. 
This version of the 
stainless steel Drop-Stop chainring is made to work with 
SRAM cranks that have a removable spider. The 
6mm offset is designed to work with 
GXP and 
Long Spindle BB30 cranks. Not sure which crank you have? Wolf Tooth has a chart 
here. If you are going to use this chainring on a fatbike crank you can find out more on proper chainline with Wolf Tooth Chainrings and fatbikes 
here.
Wolf Tooth Stainless Drop-Stop Direct Mount Chainrings can be used with 9/10/11-speed drivetrains but it is recommended that you use a 10-speed chain with a 9-speed drivetrain.
