Shimano CS-HG31 Altus 8 Speed Cassette
Genuine and nice product.
I purchased it for my btwin 520. It was not available with decathlon. It is a very good product for the pric. Very happy
Upgraded from a 7 speed system to this. It Is running on my cycle with absolutely no issues.
As usual, fast delivery, quality product. Keep up the good work. See you next time
