Well, it worked. They jumped on me on the 11th and 13th when Sprinting and I saw that there was a possibility to change the crowns industrially, and I wanted to try it and it was a success. I feel more at ease now, I had also bought a cassette but now I can enjoy my scooter a little more.

The order arrived, as expected, it took a little while. But it arrived okay. It would be ideal if you sent it with another courier other than Mail Americas, since you can never know the real status of your product. Entering to track your order doesn’t tell you much, but regarding the product, it’s compliant.

I bought these sprockets and the delivery company Ecoscooting, which is complete garbage, did not deliver them to me even though I had indicated a pickup point. I contacted the seller and they quickly refunded me the amount. I bought them again and they finally arrived. They are of good quality and 100% compatible with a Shimano cassette.

In the same order, I bought the 11 and 12 teeth crown.
When I installed this chainring, the 12 and 11 teeth ones, the chain would skip because they were misaligned, solution, leave the old one that wasn’t as worn as the small ones.
Now they are working quite well for me.

Good, really strong, but the ends are closed so can’t put it at the middle of the free wheel, just need to grind them, took 3 days
