absoluteBLACK Premium Race Oval SRAM Inner Chainring
Proven to feel more natural and rounder than standard chainrings, absoluteBLACK's Premium Race Oval SRAM Inner Chainring's elliptical shape delivers optimum pedal efficiency and reduced risk of muscle cramps or injury. Perfect for hill climbs, the oval shape utilises more muscle groups throughout the gyroscopic pedal motion, meaning fresher, more energetic legs, increased power output and a higher maintained speed.
Additionally, this unique chainring has been designed with smoother gear shifting in mind. Constructed with 12 downshifting and 6 upshifting points, this inner chainring ensures seamless gear transitions with improved chain stability.
