Description

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 110×4 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
