This is an interesting design from LDG:

“We took a different approach to traditional cog design and started thinking out the box. The outer teeth are CNC’d from 7075-T6 heat-treated aluminum and mechanically fastened through six stainless steel, and two brass pins, to the body. The body is sculpted from a solid piece of stainless steel and precision crafted to house the outside teeth. The amount of precision it takes to pin the outer cog to the body meant that we had to machine all facets of the material to ensure the pins would properly seat. The outside cog was anodized black and then further machined for a two-tone look.

The first production run of 15T will be available soon, followed by a release of the 16T, 17T and 18T sizes shortly after. Pricing will be set at $59.99 each.”

I feel like companies come out with versions on this design every few years but this one takes an interesting approach. Thoughts?
