I have Rant cranks and they make a loud ping noise every so often. Did I break the weld or something?

Bearings are fucked.

YES. I didn't want to spend $150-200 on new cranks. What are some good mid bearings?

you can just go by looks. whichever one you think looks the best or matches a theme on your bike, get it. most bottom brackets consist of the same quality bearing.

This. Most beautiful way I've ever heard it said.

if it's only every so often that it happens, it could be your cassette skipping too

it could also possibly your chain, I had the same problem and thought it was just my hub skipping then my chain snapped and I ate shit

Not necessarily, could be loose, could need grease, could be cracked, hard to say.

INSPECT THEM.

Take your chain off the sprocket and spin them by hand slowly, you can typically feel if bearings are bad.

Check your pedals, could be them clicking.

Don't just take someone's word who isn't there inspecting them.

Hell it could be your chain pinging off you frame on hard landings.

When does the sound occur? Landing? Pedaling? At a certain point in the pedal stroke?
