ABSOLUTE BLACK chainring direct mount oval Cannondale Hollowgram crank | black
Premium chainrings for Cannondale Hollowgram cranks with 1-speed drive. Absolute Black chainrings are CNC machined from one piece of aluminum and then anodized. The result: an extremely stiff and durable chainring. They were developed for 1 x 9, 1 x 10, 1 x 11 or 1 x 12 (SRAM Eagle) drives. 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 drive train and optimizing the resistance. When kicking with the legs, the natural strengths and weaknesses are brought into harmony. In this way, better use of the stronger muscle groups is achieved and a balance is created in the weaker muscles on the way to work (lower stroke). The ovalization and the point of maximum power transmission have been adapted to each chainring size separately in order to ensure the greatest possible efficiency.
