I'm working on the chain. I ordered a new chain. I hung both chains from a nail and I see the new chain is three inches longer than the old chain. So I need to shorten by three inches? I ordered a chain pliers but didn't change the address on the Amazon account and it was sent to my brother who's in prison.

Hoping the guards don't assume it's something to help him escape. Regardless, are there any online primers for replacing bicycle chains? I used a grinder to get the old one off.

TIA,
