ABSOLUTE BLACK chainring Direct Mount oval | 12-speed HG + for Shimano XTR M9100 / XT M8100 / SLX M7100 crank | PVD rainbow
High quality direct mount chainring in stylish PVD rainbow look.
The matching oval direct mount chainrings for Shimano 12-speed cranks . Absolute Black chainrings are CNC-milled from one piece of aluminum and then PVD coated, the result: an extremely stiff and durable chainring. 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. With an offset of 51 millimeters, the chainrings are suitable for both 142 millimeter standard and 148 millimeter BOOST rear wheel hubs. Thanks to the special PVD Rainbow Titanium coating process, the chainrings are very durable and incredibly individual.
The ovalization of the chainrings increases the 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).
Note:
The teeth of the chainrings are specially designed for Shimano 12-speed HG + chainrings and only work with the corresponding Shimano CN-M9100 / M8100 / M7100 HG +) chain.
