140mm Single Piece Square Taper Crank Arm for Cycles

This cycle hardware crank arm is a single piece cycle component built for crankset use, with a square axle bore at one end and a threaded pedal hole at the other. Its straightforward construction makes it easy to identify as a practical replacement part for riders or builders working on a compatible setup. With 140mm crank arm length and about 170 mm overall length, it offers a compact format that fits bikes and exercise equipment needing a shorter lever arm. The curved, slightly tapered shape helps define the part’s aerodynamic profile, while the measured 12.8 x 12.8 mm square hole size, 24 mm crank end section, and 12.5 mm pedal end section show the fit of the component. Finished in glossy black, this black crank arm has a clean, simple appearance that blends well into a variety of builds. It is intended for cycle and exercise bike crank use, making it a practical exercise bike crank arm for indoor training equipment or everyday bicycling hardware maintenance.
