Although we offer Titanium Nitrided cassettes (Listed above), which are harder then any material your cassette is ever likely to come into contact with, we always like to go one step further...
We are constantly researching into the latest technical advancements, producing test pieces and prototypes, with the sole intention of providing the best products in the world... Our Titanium Nitrided cassettes provided the ultimate durability and shifting performance, and still do under most circumstances, although we now have an even harder, slicker product available!
Titanium Aluminium Carbonitride is a blue/black coating with hardness rating in excess of 3000HV (Practically Diamond!). It has the lowest friction and highest coefficient of wear available.
This process allows high speed cutting tools to work at temperatures in excess of 800degrees, outperforming (TiN), as it can be used under much heavier loads and even 'dry machining' without lubricants...
"Why do we produce the hardest cassette in the world? Because we can...!"
We offer custom Tune full titanium cassettes with ceramic spacers, for Shimano 9 speed
