Since Tree had a few issue with the original 4130 sprockets, they decided to change the material and make it stronger. They machined a piece of 4130 chromoly, made it thinner, but yet stronger. The sprockets are available in 25t, 28t and 30t sizes, all with spline driver and in two color options black and raw. If you are a minimalistic person and love clean style, this is definitely something you need to check out.
