WELCOME TO
Prime9

Prime 9™ Technology is a counter-intuitive philosophy based on the less is more theory. It embraces range without adding complexity. The outcome is fewer parts, reduced weight, and increased durability.




Less aggressive chainline vs. a 12-speed system. Be prepared for less system wear and tear.




All those clicks add up. Spend less time shifting and more time riding.




Fewer cogs on the cassette reduce system weight.
