The disappointment, if there is any, comes as you move up through the levels. Here's the first blind test you can conduct. Take those beloved 930s that are being talked about here. Find a 530 and 730 frame from the same year in the same size. Paint/decal them up the same where they look exactly alike. Put identical components on them. Your choice. Don't weigh them, although there will not be too much variance in the weight. Now go out and take them on blind test rides. Who amongst us thinks they can pick out the 930 frame? Who thinks the 930 frame will be their favorite? Now lets expand that some. Let's get other manufacturer's competing frames from that year with the same size and similar geometries. Let's paint/decal them up where they look the same as the 3 Treks. Let's mount identical components/groups and take them all on blind test rides. Who thinks they can identify the 930? Who thinks it will be their favorite? After the rides, the most likely outcome is that the 930 will not be identified. Might not be the favorite either. Might not even be in the favorite top 5. The sentiment will be they are all great bikes. You can't go wrong with any of them. You might prefer one or two a smidge more than the rest of them. That's the reality, I'm one of the few that will admit it. That's what makes the hobby fun. Searching for the one that will change that. It's not out there.
