Frienda 10 Pieces Bike Bicycle 7 8 9 10 11 Speed Cassette Washer Anodized Aluminium Alloy Flywheel Hub Washer 1mm 1.5 mm 2 mm 2.5 mm 3.0 mm Bottom Bracket Washer

I bought these to help me fit a 10-speed cassette on an 8-speed hub (requiring 1x1mm spacer). The spacers themselves aren't great quality but worse still they were far too loose around the free hub, so wouldn't sit evenly. The cassette once fitted would spin at an angle. Very poor purchasing decision and I will be looking for genuine Shimano parts going forward.
