From Google...
The OneUp Carbon E-Bar (35mm rise, 800mm wide, 8° back, 5° up) features etched degree markings in the stem clamp area designed to align with your bike’s head angle. By matching the marking to your head angle and aligning it with the stem faceplate, you create a neutral starting point for optimal vertical compliance and proper sweep.
However, when I set to 64° them to match the HA on my bike they're rolled super far forward and the upsweep feels crazy. To get what I feel is a comfortable position when sitting on the bike I have to roll them back to the 70° HA marker.
I normally just set my bars by feel but as these are ovalised to offer a certain amount of flex/compliance, -6° seems a bit far from the suggested neutral starting point. 2 or 3° either way I could understand but 70° is the very last marker line.
What say STW, other than "you're over thinking it" (which I am 😀)?
Show us a wider pic of the bike's front end please.
But yeah, probably just ride it 😀
Ummm, there are instructions?! For a handlebar? I just put mine on like I do with any other bar, set by eye, rode them, tweaked slightly, then they blended into the background!
Surely lining then up with the gap only works if the gap is in the same place on every stem, which it's not. Unless that's a OneUp stem, which is likely what they modelled it on, making my point moot...
Reading those instructions again, bear in mind the phrase 'neutral starting point'.
To quote kids, 'just send it'.
Do what feels right, handlebar roll is a very personal thing. I hate the feel of rolled forward bars.
@Ben_Haworth The sun is out for the first time since 21st Jan so I'll try and take it out for a quick lunchtime ride and get some photos.
@submarined Indeed. The only instructions I usually pay attention to for bars are the torque values. It probably is designed to work with the OneUp stem.
@dc1988 Yeah that's what I've always done, go by what feels right. I was just confused as to why the numbers didn't seem to align with the suggestion. I hate forward roll too.
It probably is designed to work with the OneUp stem.
This.
I Just set mine by eye - combination of looking at the roll, and trying to align the narrow bars of the ovalisation roughly perpendicular to my shoulders.
Fantastic bars, feel great, really comfy and I'm a fan of the flex.
Eye ball and feel it is. I'll stick with tried and tested methods!
Really looking forward to trying them out as everyone who has them always seems to sing their praises.
Oneup bars are designed to give the most flex when the rise is perpendicular to the ground - ie straight up.
You can roll them back however you like. The two normal starting points for handlebar roll are rise in line with the steerer (ie rolled back), or straight vertical (like Oneup recommend here). I tend to treat these as upper/lower thresholds and settle in-between these points.
IIRC the V2 bars have different markings, and allegedly give more flex over a wider angle range.

Did a quick 10 miles on my lunchbreak including some gnarly stairsets and didn't think of the bars once, which I'll take as a good sign.
Not being very clever, I'd imagined that maximum flex ought to be perpendicular to the head angle, i.e. the direction of force coming up the fork and so you'd NOT compensate for head angle (shruggy emoji)??
I set them up so the rise is vertical…and just to ensure I get all the flex, I put them on a rigid bike 🙂
In combination with some revgrips it solved my painful golfer’s elbow problems without resorting to squishy forks!
I've had two rides on mine now and they feel good, though I might roll them forward a degree or two just to see what it feels like.
