If you take a look at either of my bikes, you’ll see my handlebars are much lower than my saddles, by as much as 3-4" on my road bike. To me, this is absolutely the most comfortable position to ride in.
Tell a non-biker how high you like your saddle, and you’re likely to hear them scoff about how your butt is too high in the air, and how it must be uncomfortable to be leaning that far forward. Most people haven’t ridden a bike since they were a kid, a point in time when it’s best to have your seat so low that you can put your feet on the ground when you stop. These people, of course, have no idea what they’re talking about.
However, there are plenty of more casual riders, such as recreational types and commuters, who do know what they’re talking about, and they still prefer their handlebars as high as their saddles, if not higher. I think both methods have their benefits, and each rider needs to determine what works best for their own body and riding style, as opposed to trying to look like Lance, when you ain’t Lance (or even close–yeah, I’m talking to you, Mr. Elderly Guy whose belly is about to burst out of that too-small, highly decorated cycling jersey), or sitting bolt upright simply because you think it looks more comfortable.
With that in mind, there’s a great discussion going on over at EcoVelo, with plenty of valid points being made in the comments section. If you’re happy with your current seating position, by all means, leave it alone. However, if you think there’s room for improvement–either racier or more relaxed–then maybe you’ll get some ideas based on others’ input.
