- High rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and quicker and more precise front shifting
HOLLOWTECH Crank Arm:
- A lightweight crankset not only reduces the bike’s weight, but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. SHIMANO’s advanced forging technology has solved the problem through the HOLLOWTECH crank. Just like high quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very lightweight.
- HG-EV cassette sprocket is for rider-tuned gear combination & cadence management. We provide optimal 11-speed drivetrain gear ratio; you can choice wider and closer gear combination available to match various riding disciplines. HG-EV cassette sprocket is obtained 11-speed gear without compromising the 10-speed durability and improved HYPERGLIDE shifting.
- HG-X11 directional chain realize more smoother shifts and greater overall performance. Right and left sides are optimized for front and rear shifting respectively.
- The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider’s power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. Naturally, SHIMANO strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company’s own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer.
The HOLLOWTECH II crankset has been developed by pursuing the optimum balance of stiffness & rotating performance in a lightweight and beautiful crankset design. High Precision Sealing Moreover, HOLLOWTECH II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods.
