Technology

HollowTech Crank Arm

Hollow forged crank arms; a light weight 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.
