The visually appealing 4-arm construction with hollow-forged crank arms and integrated Hollowtech II axle stands for an optimal ratio of weight and stiffness for maximum drive efficiency. The cranks and chainrings themselves are made of anodised aluminium, while the fibreglass-reinforced plastic ribs on the back of the large chainring embody the SHIMANO 105's special structural design, which allows for significant weight savings with crisp shifting performance. \u003cbr\u003e\n\u003cbr\u003e\nWith a difference of 16 teeth, the chainrings in combination with the matching 12-speed cassettes from SHIMANO ensure a high bandwidth with fast and easy gears and fine gear jumps at the same time.
