Samox JIS Square Taper Crank Arm - Left Info
The Samox JIS Square Taper Crank Arm - Left is a straightforward replacement crank arm built around the JIS square taper interface — the standard found on the vast majority of traditional Japanese-spec bottom brackets. When your original left arm is worn, damaged, or simply needs replacing, this gives you a clean, compatible solution without pulling apart an entire drivetrain.
The JIS square taper spec is subtly different from the ISO standard, with a slightly shallower taper angle that positions the crank arm closer to the bottom bracket shell. Using the correct standard matters — pairing a JIS crank to an ISO spindle, or vice versa, affects chainline and can cause premature wear. This arm is the right tool when your bike calls for JIS.
