These new chainrings come with a new design, more compatibility and lighter weight. ROTOR engineers have worked in detail on these chainrings, solving the problem of compatibility of the previous Direct Mount chainrings with the new Shimano 12-speed groupsets. They also incorporate our patented Universal Tooth® technology to ensure total compatibility with 11-12 speeds groupsets.

The new design is more than just aesthetically pleasing: we've worked on a sleeker, more robust and precise structure, with clean lines that reflect our obsession with engineering. Refined CNC milling, coupled with a deep, durable anodised finish, delivers a sophisticated look that also stands up to the most demanding conditions.

ROTOR's Universal Tooth® Technology is a patented tooth design for 1X and 2X chainrings that is specially optimised to offer compatibility with any chain on the market.

Thanks to a complete redesign and direct integration to the power meter or crank, we've managed to reduce weight by 30 grams compared to a traditional configuration with BCD110x4 12-11 speed chainrings. Every gram counts when it comes to performance, and this improvement translates into a more responsive, more agile bike with a cleaner look.
