How much time will clip on aero bars shave?

Say you were doing a 7 mile tt. First time you did it, it took 17:12. How much time would a set of aero bars take off?

Yes. The absence of humans won't mitigate perceptible vibration and sound waves. The question is what the sound will be, depending on the variability of the tree that has fallen.

Oh, come on guys, be nice :-)

Obviously, we can't say how much time you'd shave, but you'd probably shave time. It depends on the wind conditions, how comfortable you are in your aero position (if you are unstable, or just not used to pedaling in that position, you could lose some power), and how good that aero position really is. Practice riding in your aero bars, go out and time trial again, and tell us how it went.

Something that was strongly impressed upon me by taking my TTs last year and comparing them to this years was the accumulation of (smallish) advantages.

Some advantages are larger than others, and certainly, aerobars can be a significant one.

In no particular order, small advantages to accumulate:
Accurate pacing (collapsing shortly after crossing the line can be almost ideal)
Fitness (always handy)
Aero helmet
Skinsuit
Efficient position (bio-mechanically & aerodynamically)


Aerobars may help, maybe a lot.
Other things will certainly help, maybe a lot.

I finished my last TT in the top ten, previously I'd finished 3.5' down on the exact same course.
I haven't turned into a TT beast in the last year - but I've spent the last year accumulating a bunch of advantages, some small, some larger.

go read the stickied TT thread at the top of the page - it's got everything you really need to know. There is no way to accurately predict what you are asking, but luckily, the biggest (percentage-wise) time gains to be found in a TT tend to be inexpensive.

best of luck as you work to get faster :-)

This.

I going out on a limb. We have a 9.7 mile training TT with flat to rolling terrain. It has many categories such as aero, Merckx, teams, men, women and tandems. We get about 100 entries per event and I have seen a lot of data on racers riding on their TT bikes and Merckx to get an idea of how much better they are on the TT bike. Typically, there is about 1:30 to 2:00 minute spread for riders doing it aero and non aero. So you can ratio off this to get a "gross" idea. Keep in mind the men who switch from aeor to Merckx ALSO are very good time trialists at making high power in the aero position. So as others have said, it really depends. If you execute poorly with aerobars or the setup is poor, you may be slower. It took me some time to get good at producing power in the aero position on a TT bike.

Sorry to hijack the thread, but I was wondering the same thing.

When im using my aero bars I can't seem to get comfortable and it doesn't seem like I'm getting enough power down,
whereas if im on the drops I not only feel more comfortable but I feel like I can get more power down.
So much so that the increased power feels more aerodynamically advantageous than using the aero bars.
Could this be because of my poor position/bike fit or do I just need to put the miles in on the bars and get more comfortable?

Thanks for your replys..

Make sure that you can still see and avoid the potholes on Angle Road when riding with aerobars. (You are talking about the Cemetery TT, right?) Your time will really suck if you have to repair a pinch flat.

If you have to apologize for something you say before you say it, it may not be a good idea to say it. Apologizing for hijacking a thread does not magically make the fact that you are hijacking the thread go away.....just saying.

Those on tt bikes and aerobar clip-ons roadies that were ahead of me all season - I rode the Merckx divistion - (10 mile tt once a week during DST) were not when the omnium specified Merckx for the tt - one to two minutes.

My power difference in a TT position versus in the drops vs on the tops is negligible.

My guess would be 20-30 seconds at a minimum, more if you go faster.
