The age of the round chainring is over.Through an exhaustive R&D process to refine the oval chainring we discovered that optimum pedalling efficiency didn't come from subtly altering the circle, it came from a whole new shape we call the 'square'. By breaking the pedalling action into 90-degree segments the rider effortlessly puts four times more power to the rear wheel. In between these peak power moments, there is the restive stage of pedalling which riders report a 90% decrease in fatigue.The unique geometric shape of the 'square' also provides our Quadrant rings with the revolutionary Parallel Chain Retention Technology. While conventional chainrings can only have 180 degrees of chain contact, the Quadrant ring has up to 270 degrees of contact that eliminates all chain drop. Forever.Easier pedalling, more power, less stopping and dropping.The Future is Square.Visit northshorebillet.com for more.
