Function of aero bars? How I'm I gonna benfit?Trevo

I like going fast, will aero bars make me go much faster?
I see them a-lot on time trials bikes, dont see them much on regular bikes.

I've read things about century bkes and touring bikes having them. Anything about that?
Iam looking at something simple like the nashbar road add- ons.
Info appreciated!

The function of aero bars is simply, as the name implies, to make you more aerodynamic on the bike. If you are slow because of poor aerodynamics, they may help you. On touring bike they are there for comfort, which is an oxymoron. The people who put them on touring bikes set them up totally wrong and only to take the stress off their hands and place it on there forearms. But if you look at their position, it is most likely not aerodynamic at all. An aerodynamic position is not cycling efficient. That is why you don't see pros on normal days riding with them. They are there to serve the purpose of putting a rider in an aero tuck for a short time trial. You will benifit much more from drafting someone than using aero bars.

So they relieve stresses hands while touring?
If I could find a cheap deal on some bars would they be beneficial for downhills If I just wanted to go really fast?

Thanks for the info

Let me say this harshly, but honestly.. you would be stupid to go really fast down hills on aero bars. Your wieght will be too far forward, you won't have a firm grasp on your bars, and you won't have your brakes within instintaneous reach. You would be risking the biggest crash of your life.

Stick with my earlier advice.. if poor aerodynamics are what is holding you back, they may help..but if that is the case, learn to sit on your bike better. And you will ride faster if you draft something.... like a truck. But have your hands where you can reach the brakes while you do.

Please don't go downhill on aerobars! Your skin and bones will thank you. If you want to go fast downhill then grab the drops and use a good downhill form.

I use aerobars on my TT bike and they make a big difference but I use them on the flats when I'm by myself. When I go down into the aerobars I can see an immediate increase in the speedometer of about 1 1/2 MPH. Then I find that it becomes alot easier to crank the speed up from there and hold it.
wow thanks! I was thinking about that NMTrevo

Russ, I have to disagree here that the aerodynamic position in not cycling efficient. Power is generally the same between a good TT position and a good road position. Look at some of the top triathletes posting average speeds of 24-26mph over 112 non-drafting miles, while saving enough energy to run a sub 3 hour marathon. That also goes to prove that they arent only for short time trials.

The reason you dont see pros riding aerobars in the peleton is because the road position is more maneuverable, and because individual aerodynamics are not a major player when sitting in a pack. You want to be able to maneuver your bike and have it handle well/quickly while in those close quarters.

Like you said, there is much more benefit from drafting than from aerobars. However, if solo efforts are the focus, like a time trial or non-draft legal triathlon, then aerobars properly fit on a bike will yield great benefits. Just slapping them on a road bike usually yields sub-optimal results.

But I thought aerobars were not allowed, other than timetrials, in pro or even amateur racing. They are considered a hazard in a peleton. Read that somewhere, can not remember where. Can anyone comfirm this?

You are correct, they are not allowed for the reasons i said: They arent good for bike handling. Some short aerobars are legal such as the cinelli spinacci (sp?), but full fledged aerobars are legal only for time trials.

Trevo,
I rode with aero bars on my road bike for some years. You do get an immediate speed benifit of 1-2 km/h average on the flat. The problem is that if they are adjusted for 'good' aero position your head is right down and in order to see you have to extend your neck to look forward. After a period of time this ended up giving me some serious neck and shoulder pain. Now back to a normal road setup and couldn't be happier. You might be luckier?

If you compress your chest with your legs when you're on the aero bars, the reduced effort for your legs will be canceled by the inability to breath properly. This is one of the major reasons that TT bikes have steeper seat tube angles, so that the angle between the legs and chest can be kept more "open" when in the aero position. A properly set up TT bike is good for around 1.5 mph vs. a standard road bike. As others have noted, they do allow you to rest your hands and arms, which is why you sometimes see them used by touring riders.
