The direct mount chainrings for SRAM cranksets replace your existing spider and chainring with one clean looking, lightweight, and stiff piece of machined billet. They are available in 3 different offsets: standard 6mm offset, Boost 3mm offset, and BB30 short spindle 0mm offset.


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:

Standard Road/CX/Gravel: 6mm offset for cyclocross and road crank applications with 47mm chainline

Standard MTB: 6mm offset for non-Boost mountain bikes, GXP and long spindle BB30 cranks for 49mm chainline

Boost: 3mm offset for 52mm chainline

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.
