Reach Rule of Thumb (Obscured Hub)

Notices
Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Reach Rule of Thumb (Obscured Hub)

Does the rule of thumb where the handle bar should obscure the view of the front hub apply when on the hoods or the drops?

Also, how should your back be positioned when you are on the hoods properly?

Whose rule of thumb? Position the bars so that your bike fits you properly and you feel comfortable riding.

I guess what I'm asking is, how do you tell if your reach is too long, or if you just aren't assuming a proper position by leaning forward enough when on the hoods?

My bike the "rule of thumb" applies to the handle bars blocking the hub when I am on the drops, but not when on the hoods. When I'm on the hoods, I feel like I'm reaching too far and I have to consciously bend my elbows. I'm new to this, so I don't know if I should try a shorter stem or just get used to forcing myself to stay down.

It's a legitimate question. The hub will be obscured at certain positions while not at others. I'm not certain of the 'rule' myself, but as for my own set up, (professionally fit), my hub is obscured when on the hoods with elbows bent and back pretty low. Change those inputs a bit, and I can see the hub. So, who knows.

On hoods, in riding postion. It's about as useful as calculating your MHR instead of measuring it.

"Wait! Rule of thumb? In the early 1900s it was legal for men to beat their wives, as long as they used a stick no wider than their thumb."

"Rule of thumb, eh? Can't do much with that, shoulda been called the 'Rule of the Wrist!.'"

Honestly, if I used the hub-obscured rule then I would be reaching way too far on all bikes that "fit" by fitter's standards. I guess you could say that it's almost obscured when I'm on the tops, but not near it when on the hoods or on drops.

Get theeself comfy.

Real men play hide the sausage, not hide the hub.

As a rule of thumb it only applies to some riders on some bikes who chose some styles of riding. If you are one of these then it may well work but it is not universal or helpful.
Peter White has a useful guide on general bike fit and addresses the issue of back angle and reach. This is a personal choice and for performance riding varies between 45degrees for tourists to almost horizontal for competative time trialists.
