Shimano SLX HG81 10 Speed Cassette

The Shimano HG81 10 speed mountain bike cassette out of the SLX series. Made for all Shimano 10-speed mountain bike groups.

Dyna-Sys technology and Chrome/Nickel coating: relatively light and durable
The HG 81 SLX cassette uses Dyna-Sys technology. This means the teeth are closer together, so less force is needed to shift gears. This Dyna-Sys cassette is made up of a lightweight aluminium spider with three sprockets, for a large surface area and high durability. The remaining cassette sprockets are made of steel, coated with a chrome/nickel coating. This benefits durability and wear resistance.

HyperGlyde: a refined tooth profile
The cogs on the SLX HG81 10 speed cassette feature HyperGlyde technology, which means you'll be shifting nice and quiet with this cassette. This cassette also works perfectly with Shadow rear derailleurs.

Mounting with special tools

Don't forget the assembly grease!

How often should I clean my bike? Regular cleaning ensures that your material lasts longer and that you can enjoy your cycling for longer. How often you need to clean depends on the weather conditions in which you ride. Do you cycle through all kinds of weather, or do you only go out when the sun is shining? It all affects the degree of wear and tear and some people will have to clean their bikes more often than others. Use the schedule below as a guide:
