Bicycle Pedal Removal

In order to tighten the pedals you must use a long 15mm wrench and turn toward the front of the bicycle. Drive side is standard clockwise to tighten, counter clockwise to loosen. However non drive side is the opposite counter clockwise to tighten and clockwise to loosen. Many customs strip the non drive side crank by rotating the pedal the wrong way....please do not make this mistake.
