Subrosa Devil Disc Sprocket

The design is bad ass and its fairly beefy for how machined it is. It comes in many colors and is easy to put on.

nothing. Maybe the price.

strong, thick, cool colors, light for how thick it is

if you don't use the adapter on the out side the cranks carve a groove around the spindle hole pretty quickly it happened to mine in like a week but i caught it before it got too bad, expensive
