Rotor DM R RING Chainring
The ROTOR Round rings 2-speed Direct Mount 12-11 speed 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. Combined to an optimized pedaling experience thanks to its oval design.
Made from a single piece of 7075 aluminium, these are lightest and stiffest chainrings for a 2-speed 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 11 speed chains and to improove the shifting. But also fully compatible now with any Shimano® or SRAM® chains, thanks to our registered Universal Tooth® technology.
