ABSOLUTE BLACK Chainring Direct Mount oval BOOST 148 | Race Face Cinch Crank | PVD rainbow
The best chainrings for Race Face Cinch cranks on the market are CNC-milled from one piece of aluminum and then anodized. The result is an extremely stiff and durable chainring. It was developed for a 1x9, 1x10, 1x11 or 1x12 (Eagle) drive. 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 resistance. When kicking with the legs, the natural strengths and weaknesses are brought into line. This achieves better use of the stronger muscle groups and creates a balance in the weaker muscles on the way to work (less stroke).
Thanks to the OCA system (Optimum Chainring Adjustment), the position of the chainring can be optimally adjusted in 22° increments and thus offers the best performance for beginners as well as for experienced riders.
This chainring is specially designed for the new BOOST 148 standard. The slight offset optimizes the chain line for the new 1x drives. Due to the special PVD Rainbow Titanium coating process, the chainrings are very durable and each color is incredibly individual.
