HOLLOWTECH Crank Arm
Hollow forged crank arms
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.
Silky driving, accurate 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.
