    I have tried other brand oval chainrings on my bikes, and found the Absolute Black work best for my application. Long rides with the oval chainring ease the soreness in my knees/legs, and I found it easier to manage my cadence on tough climbs. PMC had the exact size and color I wanted, and I could not be more stoked!
