Absolute Black

Oval 76 BCD Chainring for Rotor, Black

Sale price Price $102.00 Regular price Unit price  per 

Our premium 1X Rotor 76bcd compatible Oval chainrings are designed for Rotor REX cranks with their original 1X spider. They are lighter and stiffer compared to the original chainring due to one optimized mounting position only. This enabled us to develop better performing chainring with super smooth pedaling sensation.


Almost all of our customers who tried Rotor before and now are using absoluteBlack, claim absoluteBlack chainrings deliver smoother pedaling sensation and allow them to pedal harder for longer. This derives from the fact that both companies have different objectives when designing the chainring. We focus on producing super smooth pedaling sensation that translates to higher cadence, increased speed, less stress on the knees and less tired legs after long ride. Rotor from the other hand focuses their efforts on theoretical gains in power and design their products with this in mind. While power gains are still not proven to this day; smoother pedaling is and you will be able to feel it yourself.
