rotating mass that is crucial for acceleration. The challenge is to reduce the weight of the crank without compromising stability and load capacity. Shimano's state-of-the-art forging technology offers an ideal solution with the Hollowtech crank. Just like a high-quality frame tube, the hollow-arm crank is enormously stable and resilient at a very low weight. \u003c\/p\u003e\u003cp\u003e\u003cb\u003eHollowtech II\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eThe concept of the Hollowtech II technology was designed to produce an optimized crankset that minimizes the amount of effort the rider has to put into the drivetrain. The high stiffness of the crankset ensures the efficiency of the power transmission when pedaling, while its light weight relieves the rider, especially on longer distances. The crankset was developed with an optimal balance between stiffness, rotational efficiency, light weight and attractive appearance in mind. Hollowtech technology allows for extremely lightweight, hollow crank arms that are manufactured using Shimano's exclusive forging technology to achieve maximum stiffness. In addition, the Hollowtech II crankset has the right crank firmly connected to the axle of the bottom bracket, achieving an optimal balance between maximum stiffness and minimum weight. The externally mounted bottom bracket offers better weight distribution and more stability, which ensures more efficient power transmission. \u003c\/p\u003e\u003cp\u003e\u003cb\u003eHollowglide\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eHollow outer chainring: The extremely stiff hollow structure reduces weight while maintaining strength.
