I was putting a cassette from my parts bin on my new wheels and encountered a very bizarre but of kit. Can anyone help with identifying this, no manufacturer markings and under 200g, 9 speed. Each sprocket is constructed in two parts; sprocket with a universal spline (looks like titanium) and then a second inner steel? splined ring for the freehub (shimano in this case), same principle as the Miche track cogs that come in two parts. Furthermore, it looks like this doesn't have the normal hyperglide ramps so I'm guessing this can be assembled without worrying about the radial position of sequential sprockets. Any help please as I want to find the manual so I can put this together properly
