Why choose Premium absoluteBLACK Oval narrow wide chainrings

Absoluteblack believe that using oval chainrings bring significant efficiency advantages to cyclists. Oval chainrings do not produce more power, they allow you to unleash your true potential. They achieve this by optimising the pedalling torque you generate, reducing your effort on the climbs and increasing your speed at the same time - so you can be faster and more efficient. Naturally, we’re obsessed with making the finest oval chainrings in the world. We do this by spending countless hours refining the design and detail of each product. Then we use the best possible materials and high-tech, state-of-the-art CNC milling machines to produce oval chainring perfection. All Absoluteblack chainrings are compatible with 10 and 11 speed drivetrains.  

Our studies led by University of Primorska, Slovenia show on the below video significant differences when using Oval chainrings compared to round. Up to 9% increase of Force effectiveness, up to 7% less oxygen consumption, up to 15% less Ventilation (breathing) and up to 10% heart rate decrease when using oval chainrings versus round. What that means? In short, You will consume less energy at the same power output using oval chainrings so you can ride for longer and/or faster. Our data show that the higher you climb themore effort you have to put in, therefore it's important to maximize efficiency and effectiveness and you can improve both of them by using oval chainrings.
