This is a one piece takes 1/2" pedals.....



This is a 3 piece takes 9/16" pedals....




....thats it really one piece is one piece and three piece is three pieces!

God bless you Laz.

When I saw yours was the only reply, I was to say the least, slightly concerned.........

Maybe a stupid question too!

BUT........... Why do the cranks take different size pedals. Anyone know?

Sounds as easy as the definition of a looptail......

I was always led to believe it was just a size and strength thing.  3 piece cranks wre an upgrade in every way, pedal axles included.

I think its cos you have:

"Normal" size pedal; 9/16, that every type of bike uses

Then you have the USA, opc, Large BB, Beach cruiser 1/2" pedal (Beach cruisers heavly influenced/evolved into early BMXs).
