The bottom line on these bikes (really!)-the frames and components aren't bad. Folks around here get hot and bothered when the subject comes up because of where the bikes are from. Dick's is not a bike shop. They are a general sporting goods store. Service after the sale, if provided at all, will be of a poor standard, when compared to that offered by a real bike shop. You are the one who has to pay for, and ride, the bike. What is most important to you?
If it were me, and I was going to spend $799 on a bike, I wouldn't buy at Dick's. Lots of great choices in your price range.
