Wolf-tooth Wolf Tooth Direct Mount Chainring For Sram Boost 3 Mm Drop-Stop A Black

These direct mount chainrings will replace your existing chainring and spider or replace the direct mount ring on Sram cranksets including the DUB cranks. The ring is attached via 3 bolts on the back side of the spider near the spindle.

Features:

• Offset: 3 mm (Boost).
• Chainline: 52 mm.
• Tooth profile: Drop-Stop A.
• Weights: 59 g (28T) / 65 g (30T) / 70 g (32T) / 75 g (34T) / 81 g (36T).
• Material: 7075-T6 aluminum.
• Made in the USA.

Compatibility:

• These direct mount chainrings will replace your existing chainring and spider or replace the direct mount ring on SRAM cranksets including the DUB cranks. The ring is attached via 3 bolts on the back side of the spider near the spindle. Note that the SRAM 12spd Red and Force AXS use a different 8 bolt mounting interface that is not compatible with these chainrings.
• Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability.
• There are 3 offsets:

1. Standard Road/CX/Gravel: 6mm offset for cyclocross and road crank applications with 47mm chainline.
2. Standard MTB: 6mm offset for non-Boost mountain bikes, GXP and long spindle BB30 cranks for 49mm chainline.
3. Boost: 3mm offset for 52mm chainline.
4. BB30: 0mm offset for BB30 short spindle cranks for 49mm chainline.

• Fat bikes: If your fat bike has a 170/177 rear hub spacing, use the standard 6mm offset.
• Praxis Works Road/CX cranks use the 6mm offset. Praxis Works mountain cranks use the 3mm offset for their DM-A and 0mm offset for their DM-B chainrings.
• 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).
• Drop-Stop A tooth profile is for all 9, 10, and 11spd chains or 12spd Sram Eagle, KMC, Connex or Wippermann chains.
• NOT compatible with 12spd Shimano HyperGlide+ chains.

Recommendations:

• Recommend the use of a clutch style rear derailleur for the best chain security.
• An L-wrench works best since the crank spindle may contact a socket adapter and prevent it from engaging properly.
• Use the same 3 bolts to attach the Wolf Tooth ring or we carry replacement bolts.
