    Advantages of Absolute Black Road Oval chainrings:

    • One of a kind special oval shape that helps you climb easier and faster (Patent Pending)
    • Over 15% stiffer than Rotor Qrings due to thicker, 5mm construction 
    • Bespoke Absolute Black 6 point ramp and recess shifting design shifts better than any other brand and model of oval chainring
    • Finest design that provides excellent strength to weight ratio 
    • You will not "feel" the oval shape while pedaling 
    • Your pedaling action will feel smoother 
    • Helps reduce stress on knees and helping your legs remain fresher for longer
    • You will be able to maintain better cadence while climbing
    • Reduces possibility of leg cramps
    • You will reduce chainring/cog shifts by at least 15%

    IMPORTANT: amps on big rings are specially configured for combinations: 50/34, 52/36, 52/38, 53/39T. If you wish to use other configuration it will also work, but shifting will be slower and may require more "adjustments" of front dérailleur to be acceptable. Also remember that front dérailleur can only accept max 16T difference between 2 chainrings - this is how Shimano and Sram designed them.

Wonderful !

Incredible piece of engineering ! Pedaling is more efficient, holding watts and cadence has never been easier. Going farther and quicker with no extra effort. And they are beautiful ;-) Love my ovals.

Will not fit stage power meter

The chainring is great and look great but doesn’t fit stage power meter (right side obviously). I had to re-machined the ring in order to accommodate the head of the stage power meter. AB should have looked into it when designing the ring. Beside that, it is very nice, light and well made. I will need a bit more time to see if it improves anything on the performances side.

Well worth the money

Really happy with these rings, my pedal stroke feels far smoother with them and nice bit of bling for the bike.
