Getting aero on a mountain or hybrid bike.

On this years RAGBRAI there were a lot of people on mountain & hybrid bikes. On the downhills some of them would lean way forward over the handle bars to get more aero. These people were so far forward they could easily rech down & touch their front tire with the palm of their hand. This looks dangerous. For one their center of gravity is pushed forward as is their weight. Though there were no accidents I saw as a result of doing this I could just imagine the result if a person on an mountain or hybrid getting aero by leaning forward hit a bump & went flying over the handlebars superman style.

If you want to get more aero that is fine, no problem with that, put aero bars on your mountain or hybrid. This allows a more aero position but keeps you from going to far foward liike I saw some of these people were doing. Ride a road bike & use either the drops or an aero bar. Or better yet ride a recumbent. But you should not put your weight or center of gravity that far forward to get a more aero position.

Maybe these people are good bike handlers, and why does it matter anyway?

I think we should have laws against getting aero on hybrids and mountain bikes, unless you have an aerobar or can prove that you have had a course by a certified "getting aero on a hybrid" instructor.

It's time for the bike safety police to take a stand and save us from ourselves.

They were doing this without their Saftey Harness!!!! Call NTSD and OSHA!!

N_C why did you go on RAGBRAI? All those miles on a bicycle sound very dangerous, especially surrounded with all those "bad bikers", not to mention the gobs of polution you were inhaling. Very iffy, you probably should have played it safe and stayed home.

As for going aero on a non aero setup, try it sometime, see how bad it really is. My guess is that rather than dangerous you will decide its just uncomfortable.

I sure as heck would not do it. Most mtbs have fairly strait forks hybrids have straitish forks. Weight that far forward will quickly put your center of gravity beyond the front axle i dont see this as bening at all safe. Personally if some one is doing that in frotn of me im gona be cuttign my speed back and let them get way way ahead of me.

not much difference from descending on a road bike. If you really want to get aero on a roadbike, you get your hands on the top of the bars right by the stem, chest on the top of your hands, face pretty darn close to the front wheel, and butt just touching the front of the saddle. Now is it safe going dowhill at 90 kilomters an hour like this? Safety's a relative thing, but people race like this all the time. I wouldn't do it in a non competive group ride, around others, but in a race, or just a descent i wanted to bomb if no one was in the way, I do it all the time.

The whole point of a MTB is that you won't go flying over the handlebars at the slightest bump. You would be amazed at the logs and boulders you can hit with a front suspension MTB without incident. I seriously doubt that there exists a bump in a paved road that will topple a MTB.

I will probably get harrassed for this but I have aero-bars on my Sirrus Pro for the off chance that I want to get out of the wind. Scarey as hell to use the first couple of times but made a big difference.

Looks can be decieving. The center of gravity doesn't change that much when leaning foward over the bars, wether the bars are flat, risers, mushtache, north road, bullhorns, trekking, or drops.

I said it looks dangerous, maybe it isn't. Maybe as diesel dan said looks can be deceiving. I've never tried it when I had a mtn bike. It does look uncomfortable though. But again maybe looks can be deceiving. I never said it was dangerous or I think it is, just that it looks as such. I never asked or said anything to anyone I saw riding this way either. All this was, was an observation I made while seeing this on RAGBRAI, nothing more.

Hell doing this was probably more dangerous on RAGBRAI then getting aero on a mtn or hybrid bike:

Picture this in your mind.

And I helped perpetuate it.
