New Chain Noise

I just got a new chain but it's a little crunchy on every crank. I know each sprocket and chain wears together so the sound may be a mismatch between my old sprocket and new chain. The teeth on my old sprocket aren't perfect, but they're not really sharktoothed.

Would it be worth it to drop $55 on a new sprocket or will it still continue to crunch and feel terrible even after replacing the sprocket because the chain just has to wear in?

I would buy a new sprocket. But then again I can't stand funky noises

It's fine let it wear in.

Make sure your sprocket bolt is tight enough

When you get a new chain it's good to get a new sprocket so they both wear into eachother evenly. The old sprocket might have been work differently from the old chain then the new chain is shaped so that might be it .

Also chains are weird too , a buddy had a BSD chain on a coaster and it sounded so bad I thought he blew his bearings . It was just the chain , pretty nasty sounding . I wouldn't worry about it . Give it time

The old chain was stretched, new one isn't, so it has to basically stretch to the old chains level OR wear your sprocket to something closer to the new chain level of stretch. Keep it clean, lubed and over a little time the noise will go away, but ideally replace both around the same time.

That tip sort of contradicts your signature. "If it ain't broke..."

Thanks for the advice guys, I decided to order a La Guardia since I didn't want the new chain to wear and stretch to an old sprocket. I've been wanting a guard sprocket anyway and a new sprocket needs a new chain so it makes more sense to get both now rather than buying another chain down the line.
