Quick Answer: Do all bike pedals have the same thread?

Why do bike pedals have different threads?

I read the question and your response regarding why left and right pedal threads are the opposite of what one might, at first glance, expect. The reason for this is due to the effects of precession, where one round object rolling inside another will turn in the opposite direction due to the clearance between the two.

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.

Do bike pedals screw on clockwise?

At a Glance: 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. Apply bike grease to the new pedals and screw them in at an even 90 degree angle.

Are all bike pedals 9 16?

Most pedals have 9/16″ x 20 tpi threads. Pedals for one-piece cranks are 1/2″ x 20 tpi. Older French bicycles used a 14 mm x 1.25 mm thread, but these are quite rare. French-threaded pedals are commonly labeled “D” and G” (French for “droite” and “gauche” (right and left).
