I think someone who wants to spend this much money on a product, and is not super familiar with the products should do their own research or seek expert opinions, in order to make the best decision.

If they want to spend $4000 on something, I think they should know enough to be confident they're spending it on the right thing, with some justification beyond 'it looks cool and the ads say it will be faster than my current bike'.

In my mind, an 'average joe' doesn't ride a whole lot, so why spend that much on something they won't use that often? Plus it can be difficult for most people to fathom the diminishing returns of spending money on bikes, and cut through the marketing BS.

I don't know what OP's expectations are, and regardless of what they end up doing, I think it would be unfortunate if they bought a bike that didn't meet those expectations.
