Wolf Tooth Direct Mount SRAM 3-bolt 6mm Offset Chainring

Compatibility:

• These direct mount chainrings 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® chainring.
• There are 3 offsets:
• Standard: 47mm chainline, 6mm offset for cyclocross and road cranks
• Standard: 49mm chainline, 6mm offset for GXP and long spindle BB30  
• Boost: 52mm chainline, 3mm offset
• BB30: 49mm chainline, 0mm offset for BB30 short spindle cranks
• Fat Bikes: If you are planning to use this on an X9 or XX1 fat bike crankset with a 190/197 rear hub spacing use the 0 offset ring.  If your fat bike has a 170/177 rear hub spacing, use the Standard 6mm offset
• If you have a BB30 crankset (30mm diameter Aluminum Spindle) this measurement will determine whether it is a long or short spindle:

• Compatible with all 10, 11, and 12 speed chains (Including SRAM Eagle)
• If using a 9 speed drivetrain use a 10 speed chain (shifts and works well on a 9 speed drivetrain and fits the ring tighter for better chain retention).

Complimenting Products:

• For a longer lasting and more durable direct mount chainring with a bashring option, check out the Stainless Steel SDMs our the CAMO System that offers Stainless chainrings.
• We recommend using a T25 L-Wrench like this one or similar for removal and installation of the bolts.
• The stock bolts are easily damaged when removing them to install a direct mount chainring. We have replacement bolts if you need them.

• 47mm on cyclocross and road with 6mm offset ring
• 49mm for standard non-boost (135/142mm rear hub spacing) with 6mm or 0mm offset (see compatibility above for which offset you need
• 52mm for Boost with 3mm offset (148mm rear hub spacing)
• 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.
