The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimanos advanced forging technology has solved the problem tough the Hollowtech crank. Just like the high quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very low weight. The concept of Hollowtech II technology is focused on producing a superior crankset, which will maximize a riders power transfer. The rigidity of the crankset ensures pedalling 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. Outboard Bearings: For most frames with 68 mm bottom bracket shells, Hollowtech II with 24 mm axle can set the bearing position outside of the frame to provide better weight distribution and more stability. High Precision Sealing: Hollowtech II cranksets have a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods. Highly rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and more precise front shifting. Original Shimano parts guarantee that all components work perfectly for optimum performance and maximum safety and longevity. ALL ITEMS ARE BRAND NEW UNLESS SPECIFIED.
