Shimano Dura Ace FC-R9200-P Power Meter 2x12v crankset

Hollowglide

Hollow technology on the outer crown, the high-rigidity hollow structure reduces weight while maintaining rigidity. More efficient power transfer and more immediate and precise chainring change.

Hollowtech

An ultra-light crankset not only reduces the weight of the bike, but also reduces rotating mass, making acceleration easier. LThe goal is to reduce the weight of the crankset without reducing its strength and rigidity. LSHIMANO's advanced forging technology has solved the problem with the HOLLOWTECH crankset. As with high-quality frame tubes, a hollow crank can provide incredible strength and rigidity at a very low weight.

Hollowtech II

A perfect balance between rigidity, robustness, weight and efficiency. Hollowtech II technology is aimed at producing a superior crankset, capable of maximizing power transfer. The rigidity of the crankset guarantees Lpedaling efficiency, while lightness, a key element of the crankset, facilitates the cyclist on long distances, where it is necessary to pedal more. Of course, Shimano has worked hard to ensure a super-light and extremely stiff crankset, two conflicting goals. Hollowtech technology, which consists of an ultra-light hollow crank arm that maintains the rigidity unchanged, was developed by Shimano with Lthe use of its exclusive forging technologies. LThe addition of Hollowtech II technology integrates Lthe bottom bracket axis with the right crank, ensuring greater rigidity, weight reduction and high dimensional stability. The bottom bracket's axial bearing system ensures better weight distribution, which translates into more efficient power transfer. The Hollowtech II crankset was developed pursuing an optimal balance between stiffness and rolling performance, and thus an ultra-light and very elegant design was achieved.
