Wolf Tooth direct mount for sram bb30 short spindle cranks

These are Direct Mount chainrings for SRAM BB30/PF30 short spindle cranks. This will replace you 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 SDM ring.

The 3rd product picture shows you how to determine if you need this ring or the SDM for GXP/Long Spindle ring. This BB30 short spindle ring is flat whereas the SDM is dished in 6mm.

** Note that these also work great on fat bikes with 190 mm rear hubs when using the X9 or XX1 GXP fat crankset -- they provide a great chainline and offer plenty of clearance for the largest tires! **

BB30 Direct Mount chainrings fit on short spindle BB30 SRAM S2200, S2210, X9, X0, X01, and XX1.
Newer S1400 (or X7) cranksets with removable spiders will work with these rings too rings. Older versions of these cranksets do not have removable spiders. If the crankarm and the spider are all made from the same piece of aluminum it is not removable.
Chainline is 50mm on a BB30 / PF30 short spindle crankset. About 55mm on GXP or BB30 / PF30 long spindle crankset.

All chainrings feature our Drop-Stop tooth design and are made from 7075 Aluminum, color is black unless otherwise specified.

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.
