Cotter Pin Continental 9.0mm - each

Many older bicycles use wedge-shaped fasteners called "cotters" to hold the cranks onto the bottom bracket axle.
These cotters have a nut to hold them in place after they have been driven or pressed in.
They can be difficult to remove, especially if they have been in place for a long time
The diameter of the round part of the cotter tends to be standardized according to nationality. Most use 9.5mm, including British, Asian and most German bicycles. French and Italian bicycles used 9mm, or sometimes 8.5mm
