Absolute Cannondale 30T Chain Ring
Hollowgram direct mount chainrings allow for flawless 1x9/10/11 drivetrain setup. Reliable, extremely light, stiff and clean looking on the bike. Chainring's specific offset creates a lot better chainline compared to other offerings on the market.
Its specially designed narrow-wide tooth profile keeps the chain really snug, allowing you to leave your chainkeeper in the garage.
Generously grease the waved shape of the crank arm, then put the chainring so that fits completely(convex side to the crank arm). Put small amount of 17px strength Loctite on the lockring threads and tighten it with torque of about 47-54 Nm.
You will need "Cannondale Hollowgram Spider Removal Tool KT012" or similar to open and close the lockring.
The most advanced, Patent Pending tooth profile on the Market guarantee minimum 12 months of excellent chain retention capabilities! We mean it. You can finally take your chainkeeper off of the bike. Tested by XC Silver World Champion Marek Konwa.
