Be well aware that when installing the PEDALS that there is in fact a RIGHT AND LEFT pedal , this being said, look carefully at each pedal as they are indicated as being either right or left! If you try to screw a right pedal on the left side crank it simply will not work,and worse if you begin threading a right pedal in the left crank,or vice versa, it will surely strip the threads!

ALSO: The right hand pedal (chain side) screws in CLOCKWISE. The left hand pedal screws in COUNTER CLOCKWISE.
