These oval 1-fold chainrings for SRAM Rannrad cranks , you will optimize your performance in the triathlon, time trial or Kriteritum. Excellent aerodynamics, top stiffness values and a performance-oriented processing ovalization will bring you to your goal a crucial step closer. Absolute Black chainrings are CNC machined from billet aluminum and then anodized, the result: an extremely rigid and durable chainring.
They were developed 11 bike drives for 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.
