ABSOLUTE BLACK chainring Direct Mount Oval Race Face crank RCA green
The best chainrings for Race Face cranks RCA in the market. Absolute Black chainrings are CNC machined from billet aluminum and then anodized, the result: an extremely rigid and durable chainring.
They were developed 11 Drive for a 1 x 9, 1 x 10 or 1 x. The chainrings have special teeth that prevent the chain may come off prematurely. The principle follows that of SRAM chainrings with X-Sync teeth.
The ovalization of the rear sprocket also boosts performance by variation in the drive train and optimizing the resistance. When contact with the legs, the natural strengths and weaknesses to be reconciled. To make better use of the stronger muscle groups is achieved, creating a balance in the working path (lower hub) in the weaker muscles.
By OCA system (Optimum Chainring Adjustment), the position of the chainring in 22 ° increments are set optimally and thus offers the best performance for beginners to experienced riders.
