SKU: OVAL-SDM30-BST-B

DM chainrings for SRAM cranksets replace your existing spider and chainring with one clean looking, lightweight, and stiff piece of machined billet

Description

More power, better traction, less shifting. Wolf Tooth oval chainrings use the brand's proprietary PowerTrac design that has all the benefits of oval, but without the funky, uneven pedal stroke. Ride one once and you’ll wonder why you waited so long to try oval!

Oval DM chainrings for SRAM 3-Bolt cranksets are available in 3 different offsets: 6mm offset for 49mm chainline, 3mm offset for 52mm chainline, and 0mm offset for 55mm chainline and SRAM Transmission optimization. They are available in various tooth profiles to suit your drivetrain, including Drop-Stop B, which is optimized for SRAM T-Type Transmission and compatible with many other chains.

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
Also compatible with Cane Creek eeWing cranksets
There are 3 offsets:
- Boost: 0mm offset for 55mm chainline required for SRAM Transmission
- Boost: 3mm offset for 52mm chainline or Transmission compatibility with Super Boost bikes
- BB30: 0mm offset for BB30 short spindle cranks for 49mm chainline
- Standard MTB: 6mm offset for non-Boost mountain bikes, GXP and long spindle BB30 cranks for 49mm chainline
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 0mm offset ring. 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 you have a BB30 crankset (30mm diameter aluminum spindle) the measurement pictured below will help you determine whether it is a long or short spindle
You will need chainring to chainstay clearance for a chainring two teeth bigger than the elliptical chainring (max diameter is that of a chainring two teeth bigger)
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)
