HOW TO MOUNT RACEFACE CINCH OVAL CHAINRING:
The chainring has a mark on the backside that you need to line up with the center of the crank arm to achieve the main/recommended position. Once this is done use BB key to lock the lockring. If you wish to try more aggressive setup, rotate the chainring from main position clockwise by one notch on the splines. This will rotate oval by further 22deg. We do Not recommend second position for beginners. Before you start experimenting with the clocking of the ring, make sure you ridden minimum 5 months in the main position first.
OPTIMUM CHAINRING ADJUSTMENT (OCA):
Our main/recommended clocking position is a fantastic setup for everyone. However some more seasoned riders may like a bit more aggressive clocking position. RaceFace oval chainring allows you to change clocking position by 22deg both ways from initial setup. This is the only chainring in our line offering this adjustability.

It also does not require chain tensioner when using in Singlespeed application. It is the most advanced oval chainring currently on the market.
