Absolute Black premium 1X RaceFace direct mount compatible Oval chainrings are designed for the CINCH system RaceFace uses to mount chainring directly to the crank. If you have 4 arm RF crank, look at 104bcd Oval ring. Advantages Direct mount chainrings: We mastered our oval chainrings to perfection, so you can get best possible advantage from the oval/elliptical shape. Finest design to provide excellent weight to strength ratio One of a kind special oval shape (Patent Pending) Greatly improves traction and climbing abilities Unique Patent Pending narrow-wide teeth profiles to keep your chain in place for minimum 12 months! Special 3D teeth machining for ultimate mud relief decrease wear and noise dramatically They save weight because they don't need the spider and chainring bolts. The ability of installation of a smaller ring sizes that can't be mounted on regular spider. Superb quality and great look. You will ride faster using ovals. If you keep using round ring then others will get quicker. You will not "feel" the oval shape at all Reduces stress on knees Why Absolute Black RF oval chainrings work: Absolute Black Oval chainrings work because a rider does not produce power evenly through a pedal stroke; they maximize the part of the stroke where power is produced and minimize resistance where it isn't. Oval rings make the spin cycle a lot smoother and are easier on legs while climbing. Believe it (or not), but a round chainring doesn't transfer torque to your rear wheel as smoothly as an Oval one. You will actually feel your stroke to be more "round" with an Oval shape than with a round chainring. Why it matters: Traction, Traction and Traction. With oval rings rear tire traction improves greatly on loose and slippery terrain. Smoother power delivery to your rear wheel means that you will be able to maintain better, constant cadence; get less stress on the joints (knees) and therefore be able to keep certain level of effort for longer. This results in higher average speed. More...
