The ROTOR Round rings 2x Direct Mount 12-11s offers you our ultimate and most advanced technology now 12 speed compatible. There is no better balance of weigh to stifness at the market due its construction.

Made from a single piece of 7075 aluminium, these are lightest and stiffest chainrings for a 2x assembly you can have on your bike. You can save up to 30g versus a ROTOR 110x4 assembly. And improve significantly the stiffness, without any nuts or bolts between the spider and the rings.

In addition, these chainrings feature redesidned teeth to work with 12 or 11s chains and to improove the shifting. But also fully compatible now with any Shimano® or SRAM® chains, thanks to our registered Universal Tooth® technology.

Minimalist and avant-garde design

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.

Universal Tooth® Technology

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.

Lighter and stiffer

Thanks to a complete redesign and direct integration to the spindle, we've managed to reduce weight by 30 grams compared to a traditional configuration with BCD110x4 12-11 speed chainrings. In addition, this chainring needs no bolts, nuts and spider, this also translates into one of the stiffer power transmissions at the market between the chain and the spindle.
