The Shadow Conspiracy Cranium Sprocket combines function and fashion to create a great aftermarket part for your bike. This sprocket gets its strength from the 7075 alloy material that it is constructed from and you can't go wrong with the skull and bones graphic. Available in 2 sizes and multiple colors.
Size: 25T or 28T
Material: 7075-T6 Alloy
Adapter: 19mm & 22mm Included
Weight: 2.6 oz (25T)
Skull&Bones looks awesome on my bike. It has a tasteful thickness, but I don't know how it holds up to smashing it on rails or ledges.
You might need a review from a more hardcore rider.
