Butterfly/Trekking bar and stem length

Hi,
There is nothing wrong with my current setup but I'm contemplating the butterfly bar for my rig. Seeing how the open end, where the shifters/brakes will be, would be closer to me then my current flatbar/barends, I imagine a longer stem would be needed for the butterfly bar. So for those who had used it before, how much longer stem do I need?

My set up is higher .. the ends of the Figure 8 bend Butterfly Bar are like the bar ends ..

Threadless fork, open face stem? you can always change that later..

since you dont say how long a stem you have I cannot guess for you.

ride it with the other bars first.

I always thought the idea was to bring the bars up and closer to you. I think a longer stem would defeat the purpose.

I always thought the idea was to have more stability as well as more usable hand positions without drops. That's kind of why mine are there.

I've also contemplated putting a set on my re-purposed Kona Lava Dome. My suggestion would be to mount the bars on what you've got and go from there. Stems a relatively cheap and it will become very apparent very quickly if you need to make an adjustment. Al

I replaced a 90mm 10 stem with a 120mm 6 stem (from my parts bucket) when I put the Nashbar bar on a Trek FX7.1. I was expecting to have to get a longer (expensive) stem but the 120mm worked fine.

I wasn't sure - there doesn't seem to be a lot of info on "how" to mount trekking bars.

I guessed, and got one 10 or 15mm longer. Well, that didn't work out.

I ended up getting an adjustable angle stem, about the same length as my original one, and fiddled with it for awhile until it felt good. Of course, It probably also depend on how you set up the bars. I set mine up, open end to the rear... but I know people put the open end front, back, up, and down...

These are mine, on a Giant Nutra I have set up as a Tourer/Commuter. I can control brake and shift from the same hand position this way.

hyhuu, I suggest you use the trekking bars on the present stem and see how you like it.

I used an adjustable stem, I have my bars fairly high.

My husband and I both switched from drops to butterfly bars this year. I find the stem I already had ismthe right lenghth, but my husband finds he's too stretched out and will be looking for a shorter one. So you really can't tell, it's probably best to switch the bars and ride with the stem you have at first.

Thank you for the responses. I intend to position the bar the same as shown in pic posted by "Gravity Aided" with the shifters/brakes at the opened end. Just looking at the photo, it is obvious that hand positions on the brake/shifter as well as the sides will be much closer to the body compares to those of the flatbat with the same stem lenth so hence the questions. But as suggested, I'll try my current stem 100mm 6deg first. My intention is to get more hand positions. I don't want high bar.

There's really a crazy amount of ways that people mount those bars and stuff on the bars. Do a little looking around before you decide on your set up. I started here: https://www.google.ca/search?q=butte...w=1506&bih=973

And ended up with this:
