This ring is functionally the same as our Direct Mount for SRAM 4 spoke ring except the 4 Spoke Rings will accept the SDM bash guards and the 5 Spoke will not.
These are SDM (TM) direct mount chainrings for SRAM GXP crank and BB30 Long Spindle cranksets with removable spiders. This will replace your existing chainring and spider, which is attached via 3 bolts on the back side of the spider near the spindle. You will use these same 3 bolts to attach the Wolf Tooth SDM (TM) chainring. We recommend using a T25 L-Wrench like this one or similar for removal and installation of the bolts.
SDM chainrings fit on SRAM cranksets with removable spiders: S2200, S2210, X9, X0, X01, XX1, X1 1400, Truvativ AKA Cranksets (GXP version), and newer S1400 (or X7) . If the crankarm and the spider are all made from the same piece of aluminum it is not removable. If you are planning to use this on an X9 or XX1 fat bike crankest, check out this explanation of chainline and hub spacing.
This decision tree will help you determine if you have a removable spider, and if you do what ring you need for your cranksets (there are 2 different ring offsets used by the BB30/PF30 cranksets):
Chainline is 50mm.
All chainrings feature our Drop-Stop tooth design and are made from 7075 Aluminum or Stainless Steel.
Stainless steel rings will last 5x or more longer than Aluminum rings
Use a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring.
A T25 Torx wrench is required to remove the bolts that secure the the chainring or spider to the crankarm. An L-wrench works best since the crank spindle may contact a socket adapter and prevent it from engaging properly.
