14 days from order to arrive - very fast shipping! the first impression is good but now i can't say how it works. it's not the first freewheel from ztto - so i think anything is ok! i recommend the item and the seller.
the 11 and 12 tooth cogs are loose. The rest of the cogs 13-28 are one piece that is screwed together. Solid and should prevent bite marks in on your free hub. Have not tested shift performance yet.
