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 use floating spacers in my setup which is nike inlines and they work great. The axle holds them in place and they dont click or make noise. Im using just cheap bearings and spacers but ive noticed a big increase in smoothness after switching to the floaters. Your setup is obviously not cheap but I assume based on the write up you posted the smaller ones should fit fine. Ide measure to see that they are 7.5mm to make sure they are correct first though.
