Aerobars on a Dahon Speed?

Hello,

I'm interested in getting aerobars for my Dahon. Looking for something that will give my Dahon more speed and ability to cut through the wind, and thus the aerobars.

I know that this will affect my fold, but I do believe that aerobars can be removed, so I shall remove them if I forsee myself folding. But I was wondering, do you need to remove everything on the handlebar (i.e. grips, shifters, etc.) before you can take it out? Or can you just loosen the aerobar by itself?

you could try a santori QR quill stem.

yes you can just release the areo bars by them selfs.However I would not recomend this as due to the long leverage they have to be very secure so as not to move on the handlebars. I would just work out how to incorate it in to the fold. I should be too hard on a dahon.

IMO, this is not a great plan.

1) In general, using aero bars makes handling a bike much more difficult. Combine that with the responsiveness of the Dahon Speed bikes (due to wheel size and geometry), the bike will be very hard to handle.

2) The handlepost on a Dahon is too tall to make putting so much weight on it advisable.

3) Since the Dahon Speed has minimal positional adjustment, it will be difficult to get aerobars in the optimal spot.

Clip-on aero bars won't permanently cripple the fold. However they need to be pretty tight (you're in big trouble if they slip), need to be adjusted properly and are usually attached using allen screws (not QR's). I.e. you can't just pop it off every time you want to fold, without investing significant time to the process.

There are very few folders or 20" wheeled bikes where aero bars are feasible, e.g. Air Friday and maybe more solid and adjustable bikes like the Swift, Pacific Reach, Dahon mini-bikes (e.g. Hammerhead).

If you're out for speed, better options include:
1) Training
2) Lower the handlebars
3) Training
4) Faster / slicker / high pressure tires
5) Training
6) Using a different bike (if you have the budget and/or space)
7) Yet more training
8) Scrupulously cleaning the drivetrain

yes, its not a great plan. But lets look at the options. What about changing bars to a set that also give the position you want, or compromising and fitting a more forward stem or bar ends in a narrow postion near the stem? Remeber you can only set up gears and brakes to be on the normal bars or the aero(unless you do something clever, or ride with one hand on each if you think you may need to brake). if you have long interrupted rides areo bars are fine, but if you dont use them enough they are a weight and handling burden as they tend to make the bars less stable no handed ect.

I had aerobars on both a speedpro and a helios sl. They worked fine for me, as my primary folding need was to put the bike in my car trunk and they didn't interfere with that. I didn't feel any more unstable with aerobars on the dahon than a full-size roadie. Yes you do have to take a hand off the bars to shift, but the same is true for clip-ons on a road bike.

If you're talking about having to completely remove the clip-ons to fold, that will be time consuming. Even loosening all 4 allen bolts so you can rotate it down will get old afterwhile.

I once tried a home mode "quick release" aerobar option - I cut the part that sticks out front off, epoxied an outer sleeve on it, then used quick-release clamps to hold it back together. My kludged homemade version didn't work too well but if the idea of "quick release" aerobars for folders caught on maybe somebody would come up with a better design.

TRiathon bars seem a better idea to me?

Hi,

Forgive me for not knowing well, but is the clamp of your Helios and Speed Pro TT the same as the one on my Speed D7? Which is, a quick release clamped handlebar. I suspect it isn't. Taking into consideration the suggestions of others, it would be great to know if our clamps are the same, because as far as I know, Dahon has different handlebar clamps, which have a direct connection to rotational stability.

As for TT Bars, I've seen them around too, would be considering them, but perhaps I will still have to use the gripshift shifters to shift, so I just need to get non-shifter brake levers. I don't think anyone makes shifters for seven speeds.
