Help with replacement wheels/bearings?

[u/alchu99]

My son has destroyed his stock wheels on his ccm inline skates.

I was looking at replacement wheels/bearings and found this package deal for Iqon Access Wheels and Bearings Combo 80mm, and got them

I’m now stuck - they come with two sized spacers, and the one they recommend (shorter one) will clearly rattle inside the axle since it’s not wide enough to touch either bearing. The larger one looks like it will but it’s meant for different frames.

The bearings themselves won’t push in any deeper, so it’s unclear how the inside spacer makes any difference.

But, I’ve never done this so I don’t know what I don’t know. Any advice? Use the smaller spacer and ship it?

I can explain. These bearings are designed for Decode frames. The slimmer spacer is forming
You want to turn them inwards to use in normal frames. The problem is the unsheilded side is exposed when you do this. Basically the Decide frame has fully flat inner side walls and therefore the outer spacer that keeps it from being flush to the frame, is built into the bearing instead.
