SDM (SRAM Direct Mount) Narrow wide chainrings

For those running a SRAM crank with a removable chainring spider, the direct mount ring can be used to save weight while looking nice and simple! It also allows for the use of smaller chainrings, ideal if you find yourself in the lowest gear too often.

The 10 blade design is optimized for maximum stiffness.
