Adapters!!! Time will tell if I give it one more star.
It came with two adapters to choose from. Not advertised. I didn't buy an adapter because someone else said that it came with one but I didn't know which one. Now I know what comes with both.

This sprocket is straight as can be
This sprocket is true,there is no bend what so ever. This is my first sprocket that I ever bought that doesn't have a bend lol the chain tension is the same all the way around . Great product

Excellent upgrade to a Tony Hawk BMX department store bike chain ring!
My 10-year old son has a single speed Tony Hawk BMX department store bike, and the stock chainring was a ridiculously large 44T, which was way too big for him to climb the hilly streets here in our neighborhood where we have 250' of elevation profile. One of the reasons I bought it for him was the 3 piece crank, which provides the option to swap out the chainring. He was so upset the day he wanted to go riding with Daddy, so I quickly made some gear ratio calculations with the 16T freewheel on his rear wheel compared to the gears I use on my bike, and I felt 28T would be ideal compromise for him. I wanted him to have a good hill climbing gear yet a ratio high enough to get some speed on the flats. My son sure likes to ride fast.My calculations turned out to be dead on- a perfect gear ratio for his little legs! From day one, he climbed the hills right alongside me, and the smile on his face is a memory I'll remember forever. Upgrade was really easy to do. His bike has a 3 piece crank, so all I had to do was remove the crank arm on the chainring side, and the gear just slides off the hub. The chainring is splined, and held in place by the crankarm and the drive pinion.This new gear fits like a glove. Build quality is first rate- looks like it was machined out of a solid block of aluminum alloy, with a lovely gold anodized finish. Looks so trick on his Tony Hawk Homer!

Ordered Wrong Size, Right Size Unavailable, Fixed It
I ordered the sprocket for 1/8" wide chain, but my chain is 3/32" wide. Tried to find this sprocket in a 3/32" width, but wasn't available. Learned that bicycles and parts are way back-ordered due to the virus.I made a setup so I could machine down the width of the sprocket teeth on my benchtop milling machine. Did that, and the sprocket works great.I suspect that many of the negative reviews for these sprockets are due to ordering the wrong size, like I did.

Kinda sketchy
Even though it took some time and difficulty to get the tracking information I am very happy with this product. One tooth appears to be chopped but not entirely sure. Looks better in person then in the picture.
