Which pedal is reverse threaded?
Remember, the left pedal spindle is reverse threaded. Turn it clockwise to remove the pedal when facing the crank arm. The right side is normal, so turn it anti-clockwise to loosen it.
Which way do pedals unscrew?
Use a pedal wrench or hex key to unscrew the pedals from the crank arms. Right pedals loosen by turning counter-clockwise, left pedals loosen clockwise.
Why are left bicycle pedals reverse threaded?
Relative to the crank arm, this radial force rotates CCW, which – via the process of mechanical precession – creates a CW torque on the pedal spindle (thus tightening it). The rotations on the left side are all reversed, so it must use the opposite threading to prevent the pedal from coming loose.
How do you tell if my pedals are 1 2 or 9 16?
If the cranks are THREE PIECES, meaning two crank arms bolted to a spindle, it will be 9/16 thread on the pedals. If the crank is ONE piece through a large bottom bracket housing, it’s 1/2 thread.
