I'm selling the product because I bought the wrong model for my 12-speed drive, but I can't return them because they were put on the bike to check if the drive is working properly - then I realized that I didn't buy the correct model (narrow-wide).

I have the original packaging
Color: Blue
Number of teeth: 11
Fits 9-11 row drives,
The wheels were not ridden under load, but as much as they were spun on the bike in an attempt to adjust the derailleur
Bought from German store R2 Bike
