Wolf Tooth SDM Boost Chainring

The 3mm offset is specifically designed for Boost-spaced frames, which typically have a 148mm rear axle width. This offset positions the chainring to achieve a 52mm chainline, ensuring your drivetrain runs smoothly and shifts accurately on Boost-compatible bikes.

This chainring is compatible with most SRAM direct mount cranksets, including DUB models. However, it is not compatible with SRAM 12-speed Red and Force AXS cranks, as those use a different 8-bolt mounting interface.

Wolf Tooth’s patented Drop-Stop wide/narrow tooth profile is engineered to keep your chain securely on the ring, even over rough terrain. The design also helps shed mud and debris more effectively than standard chainrings, reducing the risk of dropped chains.

Yes, this is a direct mount chainring, meaning it replaces both your current spider and chainring with a single, integrated piece. This simplifies your setup, reduces weight, and increases overall stiffness.

You need a 3mm offset if you have a Boost-spaced frame (148mm rear hub spacing). If you have a non-Boost frame (142mm spacing), you would typically need a 6mm offset chainring instead.
