Thread SizeUpdated 2 months ago
Thread size for pedals is determined by your cranks. Most modern day BMX bikes (that aren't cheapies from the department stores) will be running 9/16 Inch Thread.
9/16 Inch Thread- Will fit 2 Piece, 2.5 Piece or 3 Piece Cranks
1/2 Inch Thread- Will fit 1 Piece Cranks
