15mm to 12mm Adapters on an SSR125

I bought a set like these and they were 15mm bearings but my axels on my ssr125 are 12mm so I bought 15mm to 12mm adapter sleeves. hopefully this will do the trick. does anyone have experience with what I am planning on doing? if so will it work?

You might want to just make sure the wheel spacers make contact with the inner races of the 15mm wheel bearings, in order to tighten up the rear axle properly.

We have sold quite a few with excellent results ...
