I am currently riding a Truvativ T30 10S flat handlebar which is 700 mm wide, and has 10 degrees of backsweep.

I am thinking about moving to an AX Lightness Poseidon Oversized 12 (up to 780 mm wide, 12 degrees of backsweep).

Has anyone got any first-hand experience with going from 700 mm wide handlebars to something like 740 mm?

The bike will be used for technical XC riding, including some jumps (but nothing huge).

Yes.

I was on an ENVE flat bar, switched to a Syntace Vector Carbon Low10 740mm 12*.

It's amazing. They had them on Amazon for a steal last week; might still be there. The listing was for the 680mm version but it was actually the 740mm. Fulfilled via Backcountry.com.

700mm. I'm only 5'6", but for technical climbing or descending, the 740mm, -10mm bar, with FlatForce stem, gets me low and wide.

I use them on both my HT and FS "trail" bikes.

Last summer, I switched from a 680mm flat bar to a 720mm 9 deg bar. As much as I want to rave about the new bars, I honestly cannot tell the difference. I have a pair of pretty sweepy (probably 12 deg) 700mm bars on my ss, and don't feel much of a difference going between them either.

I have a 710mm on my 29er HT and 740mm on my 26FS. The difference is in the steering. The 710 feels a bit more responsive. The 740 (just installed 750mm) on the FS feels more stable when you're hauling ass over more technical terrain. I'm about 173cm.

I have found that the more sweep...the less I can get my elbows out when in the "attack position". Two degrees probably won't have a big difference.

I went from 700mm 3T last winter to a 750mm Tune Türnstange. Felt pretty good but for my new bike this year I'm down to a 720mm Tune Türnstange handlebar. Should be perfect for me.

For me, the switch to a 12 deg bar is more important the the extra width. I run between a 700 and 710mm. The Syntace factor 12 degree is awesome. I used them back when they only had the +10mm in 680 width and loved it back then. Now, I have one of the +5mm and a -5mm, both in 12 degree. LOVE them.

I also have Enve sweep flat bars, at a 9 degree and the Niner RDO at 9 deg.

The 12 degree bars are a bit heavier, but the angle feels great. Just remember, you can always trip it down if you find it to be too wide. I think you'll love the extra sweep.

Thanks. I'm probably going to try it out.

As Getter mentioned above, less sweep will help you get into a elbows up/out "attack" position, whereas more sweep will tend to tuck your elbows in toward your body more, putting your forearms parallel to the bike.

I think that it's no coincidence that you see most DH and trials riders running bars with less sweep, for their short and intense efforts that require a lot of body english, whereas a lot of long distance marathon/endurance gravitate to more backsweep or even "Alt" bars with extreme backsweep. This allows them to get the upper body into a nice relaxed position for hammering out long days with maximum efficiency.

Having said all of that, the wider the bar, the more backsweep it should have, all else being equal. You can see this simply by holding your closed fists out in front of you side by side and then spreading them wider and wider apart. You will find that the natural angle of your wrists changes to match a greater bar sweep.
