King of the Ring.
Narrow-wide chainrings are one piece of the puzzle allowing for game changing single-ring drivetrains. Tooth retention on the OneUp Direct Mount Narrow Wide Chainring works in conjunction with a rear derailleur's clutch so you can run a 1x drivetrain without any chain guides. The alternating tooth profile fits closely to the chain's inside plates holding the chain securely in place. A reinforced wide tooth design provides maximum ring durability when run without a bash guard and the aggressive crud chamfers offer excellent mud shedding performance and extend the ring's life. The Race Face Oval Cinch Direct Mount model allows you to mount the chainring directly to the crankarms, shaving the unnecessary weight of the spider and chainring bolts and allows for smaller chainring use to tackle the steepest climbs. These oval chainrings feature 12% ovality at 115-degrees clocking from the crank arm to put the major axis of the oval in your most power position of the pedal stroke. This efficiently utilizes your strongest muscle groups for the most efficient power, while speeding up the stroke through the weaker zones smoothing out the torque to the rear tire and allowing for a perfect spin. Available in even sizes between 30-34t and in the color black.
