I'm kind of confused:

Stampede 4x4 has 21 bearings:

5114 | 5x8x2.5 | 4 pcs
5116 | 5x11x4 | 7 pcs
5117 | 6x12x4 | 2 pcs
5118 | 8x16x5 | 2 pcs
5119 | 10x15x4 | 5 pcs
5120 | 12x18x4 | 1 pcs

Is this correct?

Does the Slash 4x4 has exactely the same bearings?

So why does the Slash 4x4 bearing Kit only count 20 bearings and the Pede Kit is 21?

For Example:

Here: http://www.avidrc.com/flexkit/?kit=2...name=Slash+4x4

and here: http://www.rcmart.com/yeah-racing-ba...?cPath=108_767

Seems as in the one bearing for the Slipper is missing.

I'm kind of confused.
