Oval chain rings
Why oval?
Oval chainrings don't produce more power, they increase your pedalling effectiveness. This means they reduce the component of your pedal pushing force, which doesn't contribute to moving your bike forward. The less force you waste the more energy you preserve, allowing you to push harder when it counts or simply reduce tiredness. This is the reason why you can ride faster with our ovals.
