Absolute Black recently expanded their lineup of direct mount chainrings to include these Cannondale Hollowgram compatible rings. Like all Absolute Black spiderless chainrings, this single ring replaces both the spider and chainring to create a lighter and stiffer drivetrain than the stock setup. The chainring is perfectly machined with the correct offset to create an ideal chainline for any single speed, 1x11, or 1x10 setup.
Like the previous iterations of Absolute Black's 1x chainrings, the Cannondale Hollowgram rings come with a narrow-wide tooth profile. With this alternating pattern of thick and thin teeth, the ring firmly grips the inner and outer plates of the chain. Secure contact is thus maintained through some of the roughest terrain without the need for a chain guide. Absolute Black's single rings were originally designed for use with SRAM's 1x11 drivetrains, but they are fully compatible with a variety of drivetrain combinations, including Shimano chains and drivetrains.
Proper installation of this Hollowgram-compatible chainring will require a Hollowgram spider lockring tool as well as a Hollowgram crank extractor. We recommend that this chainring be installed by a reputable Cannondale dealer.
