I either strip or etch the chrome with either emery (abrasive) cloth or bead blasting, or more often combinations of above. This is done according to the condition of the chrome, the amount of chrome to be removed or saved, and how well the chrome is adhered to the substrate.

It's difficult to be precise without the frame in hand, and the process sometimes evolves as the frame is being prepped and the surface does or does not do as is expected.

Shooting in the Dark...................

First, wash and degrease the frame thoughly, then.................

I would mask the chrome to be saved, then gently bead blast the areas to be painted.

If you can put a lightly frosted/matte surface on the metal without causing the chrome to lift/pucker/peel......... you have succeeded, congratulations you're ready to begin cleaning/ degreasing (again) /etching the frame for primer and paint.

If-/-where the chrome starts to lift,

a) there is corrosion (rust, oxidation, etc.) under the chrome 1) strip more aggressively in the areas with corrosion, and/or 2) if chrome starts to peel, switch to abrasive cloth, or adjust technique with bead blaster

b) if there is no corrosion, 1) switch to abrasive cloth, mild pressure, buffing action 2) adjust bead blast technique, reduce air pressure, or increase nozzle to object distance, or change the angle you are directing the spray at the object (should be approximately tangental, more or less)

When you have a uniform matte finish, with any lifted chrome removed back to sound well adhered material, quit, you're done, move on to the next step.

I hope this helps, if it's as hot there as it's been here the last few days a few pints or a nice cold gin-n-tonic will help even more

Good luck, you're welcome to send pics and questions directly (off list) and I'll be able to offer more specific suggestions.
