Race Face: Own recipe for oval chainrings
The new oval chainrings from Race Face are designed to distribute power unevenly when pedaling. The largest circumference is used in the pedaling phase when the most force is applied to the pedal. The smaller circumference is used to accelerate overcoming the dead spots. According to the manufacturer, oval chainrings make the pedaling motion rounder and facilitate pedaling on climbs. Compared to conventional round chainrings, they are said to offer improved traction control, especially in situations with high torque and low cadence.
The oval chainrings from Race Face allow you to vary the degree setting up to 22 degrees in two directions from the initial set-up. It is the only chainring with this adjustment option. By turning the chainring 180 degrees during assembly, the sprocket is Super Boost compatible.The Race Face cinch chainrings are available in four different sizes: 28, 30, 32 and 34 teeth. Race Face arrived at an optimal 112.5° "clocking", the angle between the crank arm and the largest diameter of the oval. This is measured counter-clockwise from the crank arm. This clocking angle can be achieved both in the normal and inverted position after aligning the crank arm with the chainring. The chainrings have an "ovality" of 10%, so the ring diameter varies between 95% and 105% of the corresponding round chainring.
The new chainrings can be combined with all Race Face cinch cranks, are made of aluminum and can be used with 1x10, 1x11 and 1x12 gears. The scale shows 72 grams for the 32-tooth chainring.
