28t is super small and makes the bike bog down a lot. But it’s made well
Perfect grain had evrything popping

Changed out for a 32 tooth and on a 20" wheel gained speed and lost minimal torque

It doesn't seem like a bad product, the adapter is offset which would be great if only it was compatible with my other cdh 40 tooth sprocket. The included sprocket doesn't make sense to me cause why off set the adapter if the sprocket is not going to go around the hub but just bolt directly to it.

Doesn’t have any threads for the brake to screw on the adapter has to be fully removed for the sprocket to be put on correctly even then 3 on the holes are way to big for the bolts

I got two pieces of aluminum, no hardware of any kind. Sounds like some customers got hardware to attach the two pieces together just not the hardware attaching to wheel.Nowhere do I explicitly read hardware is even included so can ya just tell me which to buy? I got the M5 25 to 30mm size but not the other.

Took a little bit of time to get everything adjusted properly but all in all a solid product. I ended up drilling out my old sprocket to fit the disc rotor adapter only because my 36t was better then the 28t where i live.
