Brompton Crank Only Spider Type LH Silver

Genuine Brompton Left Hand Crank Arm. This crank arm is suitable for the modern Brompton Spider Crank, which has a replaceable chainring.

The left-hand crank arm (non-drive side) has a built-in tab on the back of the crank to prevent the pedal from hitting and scratching the frame when folded. If your crank arm continually comes loose, then chances are the square taper has been damaged, and you need to replace the arm.
