I know there has been many threads about road bikes vs. tri-bikes, but I have another newbie question.

In an oly or sprint distance, what speed and/or efficency is gained with being down on aerobars vs. down in the drops? I do not have much money to spend and I was wondering if I can ride down in the drops for the majority of a race ride would it be that much slower than when on aerobars (assuming all other things equal).

Thanks for your advice.

For some reason a rule stands out in my head....only ride your drops when you are going down hills....on flat ground ride the brake hoods, and uphills put all of your weight towards the back of the bike, and little weight on your handlebars (holding your handle bars on the front portion near the stem).

For a sprint or oly, I don't think there would be any major advantage in having aerobars. You'll probably be able to draft for most of the race anyway. I'm planning to do a HIM without aerobars on a road bike. I think the only difference is comfort, with it being hard to stay on the drops for any length of time.

I'd disagree that aerobars are not valuable in sprints or oly races (unless they're uphill)...from my limited experience (3 oly's), i noticed it can be the difference between pedaling and not pedaling to keep a particular speed on a downhill...extrapolating that to other grades, it must be pretty valuable to your speed in general and the way you feel hopping off the bike...

A proper aero position isnt just about being low, its streamlining your proile, too. Your elbows come in closer to you body, improving airflow. A decent aero position is MUCH faster than the drops or hoods on a road bike for the same effort.

This means that yes, it does make a difference even in short races. You wont have to work a hard on the bike, saving energy for the run.

I've just got aero bars and i've found that effort vs speed, there's a fair amount of difference, especially in windy conditions..
And I dont know about over there, but in my part of the world almost all sprints/oly's are non drafting..

Riding in the drops is almost as aero as clip-ons. Before I had aerobars I always rode in the drops for races. Road races, crits (well you have to be in the drops for cornering because your center of gravity is lower and you can lean your bike farther before you'll skid), time trials, triathlons, everything...

The difference between hoods vs drops is bigger than the difference between drops vs aerobars...

Depending on your bike's set up (make sure you have proper fit), riding in the drops may compress your hip angle and possibly take a little pwoer away. Also, the aero position, with a foward seat can make a big difference in a short race as you can really hammer the quads on the bike and save the hammies for the run. It may only be a few seconds or minutes gained, but look at the time differences in a sprint or oly -- every second counts.

The drops to do compress the hip angle a tad...but riding aero up hills compresses the chest when you need it most. That's when you should be on the cow horns...
Really...we go back and forth about this once in awhile... Friel,Byrne and Charmichael all state that you can produce more power especially on hills with drops (years ago they were called Maas handebars). Drops allow you to move around more and use different muscle groups.Better in the long haul...Myself...I think you can descend more aggressively with traditional bars...You can definately climb better with them.
There are those that will disagree with me...
Find what works for you and in which configuration you produce the most power.

I'll climb in areo for all but the steepest climbs. I feel like I have more power that way. Don't have a powermeter - so don't really know. I use the drops on a fast downhill if it is technical.

I agree with you here, BUT just because you can push the same speed in the drops as you can on aerobars (assuming a proper set up, of course) doesnt mean its as efficient. My money says that a power meter would show a significant difference in power spent to keep the same speed for X distance.

Per Charmichael: "The most economical climbing position is seated with your hands on the top of the handlebars....Not only is your heart rate lower but you also breathe more easily because your upper body is not crunched up." (Friel also makes this point. Pg 76 "Going Long")
Friel: "For all athletes there is a trade off between power and aerodynamics. When you need to make a choice between the two.you are usually best served by choosing power.It takes alot of aero to overcome any material loss in power." And "Keep in mind there is no right bike or right position....As pro and elite age-groupers show,a wide range of setups can be both comfortable and powerful." More: In setting up your position,remember that nothing matters as much as achieving one that is comfortable." Still more:Generally the steeper setups that are appropriate for bullhorns don't climb as well..."
And finally..."So long as your bike is both safe and comfortable,you'll be fine."
From the USA Cycling Level Coaches manual: "Although aerodynamics is important to the racing cyclist they should not be overemphasized. Many gadgets and gimmicks claim to cut the wind for cyclists, but the aero advantage comes primarily at the higher speeds maintained by elite cyclists. It does not make sense for a NOVICE (emphasis mine) rider to spend money on equipment that reduces air resistance in an effort to increase speed."
Find what works for you as we all have...comfortable and powerful....with of course the underlying theme being,"Bike handling skills or Hospital bills!"

Due to the limitations of their Flash based site, this link requires some clicking to get to the video but it's an excellent example of what can affect aerodynamics on a bike.

Obviously we're not going to run out and buy aero helmets and wear full skinsuits but if something like a steady head position can shave a minute on a 40km TT then imagine what settling down into your drops or aero bars will do for you compared to sitting back on your hoods.

Great point. I agree that it may not be the diffrence between being a mid-packer and an elite, but having more energy off the bike to run is a key part of shaving time.

Is there any one who has made the transition from drops to a clip on aerobar who has seen improvements in performance?

There's definitely an advantage to having aero bars over just using the drops. Even in bike races when everyone sits on their drops, I'll get on my elbows on the bars if I'm up on the front of a breakaway or chasing through straights. Last week I won nice little beer cooler in a prime at a crit (it was obviously a joke prize, but I've already gotten some good use out of it!) when a teammate and I attacked off the front of the peloton. We went side-by-side on the home stretch, he in his drops, me on my elbows, and even though he's a stronger rider, I took the prime. I can feel an obvious difference with my elbows tucked in on aerobars compared to using drops.

I think it depends of your goals and kind of races.

If you're a finisher and no matter with your ranking perhaps better save your money for another think.
On second place if most of the race your are planing to do is allowed drafting better save your forces inside the group :rolleyes: and if you give relief you can use the drops for this short times;) .

I have one of these on my road bike. It's a nice compromise. It would easily help you out in a sprint distance triathlon. I typically use it when I'm out in front of the pack taking my turn at pulling. It definitely helps.

Here's a nice, but technical, article on why just slapping clip-on tri bars on a road bike may not be the way to go.
