HOLLOWTECH Crank Arm
Hollow forged cranks
An ultralight crankset not only reduces the weight of the bike, but also reduces the mass in rotation, facilitating accelerations.
The goal is to reduce the weight of the crankset without reducing its strength and rigidity.
SHIMANO's advanced forging technology has solved the problem with the HOLLOWTECH crankset.
As in the case of high quality frame tubes, a hollow crank can guarantee incredible strength and rigidity with a very low weight.
