Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

aero bars on a mountain bike?

Any reason I couldn't put aero bars on mountain bike handlebars? I have a mountain bike on a trainer and it seems like I could get some pressure off my elbows if I could get down on aero bars.

Thanks,
Derek

shouldn't be a problem. i'm guessing you could clip the aero bars on the mountain bike straight bars. just make sure that the straight bars have room on them where the aero bars need to clip on.

On a trainer, if it gives you more comfort over the hours you will spend on this over the winter, do it. The diameter of you MTB bar may differ to your roadie making mounting difficult but not impossible.

Also, if you take your MTB w/ aerobars up to a ski resort to do some gravity runs, please make sure your health insurance is paid up in full and have a buddy come with you to take pictures of the high speed crash.

Thanks for that second piece of advice.

There does seem to be something fundamentally wrong about aero bars on a mountain bike, but I do think it would help.

jhota is that your bike with the Scott Bars? I had the same bars on my 1990 Diamondback Apex. Man, those must have been the heaviest mountainbike bars ever! Getting the grips on those puppies was such a pleasure.

7rider - yep, that's my 91 Trek 930. the bars don't seem that heavy, though. lighter than the stock bars, anyway.

putting normal grips on them is an absolute b***h. but i haven't used "normal" grips on them in ages. if you're familiar with those nasty foam drop bar grips you used to see all the time, Spenco used to make a neoprene version. i bought a set (four pieces) way back when - they're reuseable, and the last pair that hasn't worn out is on there now. tape the rest and et voila! only takes a few seconds to get them on, too.

It'd be fine for a trainer ridden indoors with the shades drawn. Just don't do it outside. A month or so I saw someone riding a comfort bike/hybrid with aero bars, and he was actually riding on them at the time. It was the stupidest thing I ever saw. His body position was still mostly upright due to the height of the handlebars and the aero bars were just doing nothing for him.

I have those Scott aero mtn bars as well. I put regular grips on them just fine. then wrapped the rest in road bar tape. I just took them off when I converted my mtn bike to a cross bike with drops. They actually worked great. I was able to get into a relatively aero position when on the parts that were basically straight and somewhat flat. The bars are not heavy, it was the plastic bridge that was heavy.

Does anyone remember what they were called? I am thinking it was the open 4 pro

there were two versions: the AT-4 and AT-4 Pro. the Pro version had a "dip" in the forward section of the bars.

I have aerobars on my Trek hardtail mountainbike with 1.25" slicks on it. Does double-duty as a road bike and a commuter for me. Thinking about picking up some rollers so I can use it inside, too.
