Review on 🚲 Upgrade Your Ride with the SHIMANO HG51 8-Speed Cassette by David Estevez

Bought to replace the cassette on the 2007 Kona Blast. The existing cassette teeth were visibly worn and moved sloppy - perhaps from running 1,400 miles a year on sandy Florida trails. The new part fits great and is exactly what I needed. The full part number on the cartridge is shown as "CS-HG51-8 aw". It came with a snap ring as expected. I installed it with no problems and so far it runs as expected. I am deducting 3 stars as it appears to have a manufacturing defect. There should be 3 pins in the gear stack, but there are only 2 (see image). We hope that the serrations on the hub and the 40Nm torque on the locking ring will solve any problems. The time will show.
