My only concern would be after use repairs, if you need for whatever reason to take it in. Dicks (at least the few I've been in) don't have a "shop", they have a guy that assembles. I've had occasional conversations with these folks and never got the impression they were particularly experienced but possibly had been moved up recently from hunting.

REI, even though a big'ish store, does certify it's bike shop folks and they do actually know what they are doing. It's also a shop. Plus if you're an REI Co-Op member, you get a 10% dividend at years end. I'm not, mind you, all that thrilled at REI's prices sometimes, but they do typically have good gear at a reasonable price.
