ABSOLUTE BLACK chainring Direct Mount oval Cannondale Hollowgram crank | black
Premium chainrings for Cannondale Hollowgram cranks with 1-speed drivetrain. Absolute Black chainrings are CNC machined from a single piece of aluminium and then anodized. The result: an extremely stiff and durable chainring designed for 1 x 9, 1 x 10, 1 x 11 or 1 x 12 (SRAM Eagle) drivetrains. The chainrings have special teeth that prevent the chain from jumping off prematurely. The principle follows that of the SRAM chainrings with X-Sync teeth.
The ovalization of the chainring also increases performance by varying the drivetrain and optimizing resistance. When pedaling with the legs, the natural strengths and weaknesses are harmonized. This results in better use of the stronger muscle groups and compensates for the weaker muscles in the work stroke (shorter stroke). The ovalization and the point of maximum power transmission have been adapted separately for each chainring size to ensure the greatest possible efficiency.
