Do you think I need to lube my new chain and cassette before first ride?
Chain maintenance is one of those religious topics; i.e., the "correct" way to clean a chain, the "correct" lubricant to use, the "correct" frequency to clean the chain, etc.
I'm convinced that whatever chain maintenance routine you use is better than doing nothing. Chains -- like any moving parts -- need to be cleaned and lubricated periodically. It's a fact of life that your tires will kick up dirt and that dirt sticks to the lubricant, thus making it look dirty again, generally very soon after you cleaned it.
New chains come with factory lubricant that is generally better than anything you could have put on yourself because the factory can get the lubricant where it actually needs to be -- on the inside. Don't touch it; just install it and ride.
Again -- unless you cleaned a new chain with a sandblaster, there is no possible way you wrecked it within a two week span.
