L / R marks are embossed on the spindle of each pedal, ensure they are assembled on the correct side (when riding the bike the left pedal should be on your left hand side, right pedal on right hand side). The right pedal has a right-hand thread (removes counterclockwise, installs clockwise). The left pedal has a left-hand thread (removes clockwise, installs counterclockwise).
3.Thread both pedals into the crank arms as far as you can by hand, then fully tighten them with the wrench. If the pedals are not fully tightened, they may become loose and damage the threads, we will not be responsible for such damages.
