SRAM DM DROP-STOP CHAINRING – BOOST – SHIMANO HG+

Our 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/Superboost 0mm offset.
These direct mount chainrings will replace your existing chainring and spider or replace the direct mount ring on SRAM cranksets, including DUB cranks. The ring is attached via 3 bolts on the back side of the spider near the spindle.
The Shimano XTR, XT, and SLX 12spd Hyperglide+ chain works differently than other products on the market, so Wolf Tooth engineers developed a completely new tooth profile to provide optimal chain retention and durability when using this new chain technology.

The new HG+ chain interacts with the chainring differently than a traditional wide/narrow design. Wolf Tooth engineers spent the time to understand how the system works and design a new tooth profile that is optimized for this system.
Engineered proprietary tooth profiles maintain the quiet and smooth performance of the HG+ drivetrain with legendary Wolf Tooth chain retention.
Prevents premature ring and chain wear that can come from non-optimized profiles.

CHOOSE YOUR OFFSET

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.

DROP-STOP TECHNOLOGY
Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile delivers ultimate chain retention and mud shedding ability.

RECOMMENDATIONS

We recommend the use of a clutch style rear derailleur for the best chain security.
We recommend using a T25 L-Wrench or similar for removal and installation of the bolts. 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
For a longer lasting and more durable option, check out the CAMO System that offers stainless steel chainrings.
