ABSOLUTE BLACK Chainring Direct Mount oval BOOST 148 | Race Face Cinch Crank black
The best chainrings for Race Face Cinch cranks on the market. Absolute Black chainrings are milled from a single piece of aluminum CNC machined and then anodized, resulting in an extremely stiff and durable chainring. They were developed for a 1 x 9, 1 x 10, 1 x 11 or 1 x 12 (Eagle) drive. The chainrings have special teeth that prevent the chain from jumping prematurely. The principle follows the SRAM chainrings with X-Sync teeth.
The ovalisation of the chainring also increases the performance by varying the drive train and optimizing the resistance. When walking with the legs, the natural strengths and weaknesses are brought into harmony. In this way a better utilization of the stronger muscle groups is achieved and in the weaker muscles a compensation in the working path (lower stroke) is created.
Thanks to the OCA system (Optimum Chainring Adjustment), the position of the chainring can be adjusted optimally in 22 ° steps, providing the best performance for beginners as well as for experienced drivers.
This chainring is specially designed for the new BOOST 148 standard. Due to the light offset, the chain line for the new single drives.
