Moment many of you have been waiting for. RaceFace Cinch Oval rings are here!

Lighter than original round ones, with great oval shape and possibility to adjust the clocking position of the ring if you want to. This is the Ultimate solution for your RF crank.
Our oval 32T ring is only 62g vs 68g from RF. But oval 32T rides almost like 34T round equivalent (RF 34T is 70g). That makes RF Next SL crank with our 32T oval ring lightest possible setup on the market (for that crank of course).


Long description:
Our main/recommended clocking position is a fantastic setup for everyone (same as our other rings in the line). However some more experienced riders may like a bit more aggressive clocking. RaceFace oval chainring allows you to change clocking position by 22deg both ways from initial setup.
RF Cinch mounting pattern is the only one out of all direct mount chainring patterns on the market (like Sram/Hope/E13) that can be rotated by every 22.5deg (16 spline design). That coincides with 2 positions that oval users love.

Our main (signature) position is located around 3.30 oclock. That means crank arm is located at 3.30 oclock when major axis of the oval is at 12 oclock (vertical). That gives greatest benefits and excellent feel of the ring.

Our second position in RF oval rings is located at 4.30 oclock. That is 22deg later than our main position. You need to turn the ring clockwise by one notch on the spline pattern. This position is favored by some experienced riders out there who already rode oval rings for few years from various manufacturers. We do not recommend it for people who just started the experience with ovals as this position is more pronounced and aggressive. We encourage customers to play with second position only when they have ridden on the main position for minimum 5-6 months (or ridden other ovals for longer period of time).

Chainring has a mark on the back side of where the main position is. That mark needs to be located in the middle of crank arm.

I was wondering when someone would get around to making something like this! Few questions, how does the 3:30 position compare to the middle position of Rotor's QX1 ring, and how does the 22 degree compare to their adjustment angle? And as the other poster asked, what are the max/min effective tooth sizes of your 32 ring?
