Simple Question - Bike Chain
Hello! I have a question that I'm sure will be really simple for people who know about bikes; unfortunately I am not one of them.
I have a Bianchi Ocelot 21 speed mountain bike and I need a new chain. Someone is going to fix it for me (thank goodness), but I need to get the chain first. For the life of me I can't figure out what chain size I should get.
Is it a simple thing to find out, or how do I go about finding what kind of chain I need?
Thanks for your help in advance!
