Spindle Interface Type The crank arm uses a Square Taper spindle interface. Please verify that your crank orientation is square and ensure both the left and right sides have the same hole.
Installation Tips
This crank arm is divided into left (L) and right (R) sides.
The markings "L" and "R" indicate the correct side for installation:
L is installed on the left side.
R is installed on the right side.
Incorrect installation will result in the crank arm not functioning properly.
