Truvativ have long been proponents of the 31.8mm clamping diameter for their handlebars, but the times are changing, and after releasing a 35mm carbon DH bar earlier this year they've now announced even more 35mm diameter handlebars and a stem to go with them. But don't worry, those 31.8mm options aren't going anywhere -- the new sizes are additions, not replacements, at least for the time being. Keep on scrolling for images, prices, and specs of the new products, which will be available in January 2018.

I'm just bummed I can't swap freely with other bars/stems.
I had 35 renthal alu bars and they were way too stiff, I switched to sixc 35 carbon and the difference is way greater than 31.8 alu vs carbon.
They are actually very comfortable and feel solid. Will not go back to 31.8.
We are not here to be fair.
And F e-bikes as well.

Because it's a popular steel tube size that came off the shelf from tube suppliers......
Needles to say it didn't take off, Dia tech (cane creek) did change their brake levers to accommodate the new size but no other companies took it on board.
This is what most PB'ers are gonna hate... The guy had the right idea! I wanna see a new bar size that has a bigger Dia at the grip area!! Yeah it's gonna be a pain with new standard brakes an shifters an such BUT, in the long run we'll have stronger lighter bars, cheaper to produce, lighter grips an more choice for those of us with bigger hands, and most importantly LESS hand fatigue an maybe late life pro lems like arthritis an RSI's in the hands..
It's a big change but one that's worth it..
Like when disk brakes, suss, an threadless H'sets changed things for the better for the industry, the bikes and the riders.
And I HATE new 'Standards'
No doubt. The wheels that came on it were trashed after 10 rides too. Amazing spec in terms of suspension, seatpost, drivetrain, etc though.
1. Take a random component
2. Make it bigger
3. ???
4. Profit!
Who cares about improvements?
And of course, I used it on a bike with an internal lower headset cup and then on a bike with an external lower headset up and it was roughly 5.5% more torsionally rigid.
In short, more research is needed.
Biggest reason to run 35mm is for aesthetics.
How about a bar that is big enough that the steer tube passes right trough the bar. Completely replacing the stem (weight loss benefits).
I have 35mm Raceface Atlas on my Swoop - I don't like the look campared to regular 31.8mm, they seem stiffer than my 31.8mm Easton Havoc Carbon bars not sure I like them at all may have to down grade back to 31.8mm
Just like when we were told that 29ers were great only to quickly back track (when it became clear that the early ones sucked) and introduce the mid-size wheel 27.
So something like 33mm bars will probably air soon....
Serious question
So... if you have a problem with your bars rotating, I would suggest using the WCS Bullmoose bars. I have their predecessor on my 1980 Ritchey, and they NEVER slip. And being steel, they are a whole lot more rigid than any new bars you will buy today.
If you don't have a problem with bars rotating, I would suggest that they are more related to the other end of the moose. Pure marketing hype.
Let me point out that many motocross motorcycles still use 7/8th inch bars, and the "fat" bar for them seems to be a 1_1/8th inch bar. I know that the forces played into the bars on the MX motorcycles I used to ride were pretty high: much more than anything a MTB can generate.
If you have a problem with rotating bars you just need to tighten some bolts.
At some torque bolts break. Even very high strength bolts. Or the clamp will crush the bars. Or the clamp itself will fracture. Or... yeah, tighten the clamp bolt. Occam's razor rules.
