The quality is appropriate for the price, but I expect durability.
[How is it used?
Since we wanted to change the number of Sprocket pins on the ESTRELLA and the Chain that was attached to it had deteriorated, we decided to take this opportunity to replace the front and rear Sprocket and Chain at the same time.
ESTRELLARear Sprocket was only available in the same size as OEM from all manufacturers, and the only way to change the GEAR ratio was to adjust the Front. Therefore, the Rear Sprocket is not that important, so we chose NTB because it is cheap and we can expect durability in terms of material.
Was the one you received as per Image?
The color is silver, the same as OEM. However, the machining accuracy is commensurate with the price, and there are scratches like dents on the surface, and the corners of the teeth have rough surfaces as if they were left uncut.
I'm not that concerned about it since my use is for commuting Main city driving, but it might bother some people.
Was the installation difficult?
If you can remove the Rear wheel and remove the Nut from the hub, you can do the replacement work yourself. ESTRELLA is especially good because it has a center stand, so you can do the work without a maintenance stand.
As a side note, if you are replacing the Chain or Sprocket at their wear limit, I would recommend replacing the Hub damper together. I was concerned that the hub damper was too thin and the hub was rattling when I replaced it, but I forgot to prepare the hub damper.
How was your experience with it?
It works fine as a Sprocket. The color matches the silver color of the surrounding plating parts and rim.
[Included Parts:were they on?
[Was there anything that disappointed you?
Although in line with the price, the machining accuracy is not that good.
