FAIR Bicycles Hybrid 31.8+35 Handlebar: Best Of Both Worlds
FAIR Bicycles launch ‘best of both worlds’ bar technology
Every few years, the cockpit wars flare up again. Not in the way drivetrain standards do—where the “new” thing arrives with a proprietary tool and a credit-card-shaped apology—but in a quieter, more personal battle: comfort versus stiffness, vibration damping versus steering precision, and the eternal question of whether the newest standard actually makes your ride better or just makes your parts bin obsolete.
FAIR Bicycles’ latest bar technology pitch lands right in the center of that debate with a deceptively simple provocation: What is the result when you add the 31.8 handlebar standard to the 35 handlebar standard? (Yes, they’re asking it like a riddle—twice, if you’ve read their blurbs.) The editorial answer, in plain language, is this: you get a cockpit concept that tries to preserve the ride feel and compatibility of 31.8mm while borrowing the localized stiffness benefits of 35mm—without forcing riders into the harshness or fit headaches that can come with going “all-in” on oversize.
The standards problem: 31.8 vs 35 is more than a number
The 31.8mm clamp diameter became popular because it offered a meaningful step up from 25.4mm in stiffness and strength while remaining forgiving enough for long days, rough pavement, and mixed-surface riding. For many riders—especially those who value “hands-on-the-hoods all day” comfort—31.8 has been the sweet spot.
Then 35mm arrived, driven largely by the mountain bike world’s pursuit of precision. More diameter at the clamp area can allow manufacturers to tune stiffness, potentially reduce weight in some designs, and offer sharper steering response. But oversize bars also have a reputation (fair or not) for transmitting more vibration to the hands and upper body, and for pushing riders into a narrower ecosystem of stems and accessories.
So when FAIR says “best of both worlds,” they’re speaking to two big anxieties: the fear of losing comfort, and the fear of losing compatibility.

So what happens when you “add” 31.8 to 35?
In the simplest conceptual sense, you’re looking at a hybridized clamp-and-taper approach: a bar that acknowledges the mechanical advantages of a larger clamp zone while aiming to keep the rest of the bar’s shape and compliance closer to what riders associate with 31.8.
There are a few ways brands typically attempt this “hybrid” outcome:
- Localized stiffness at the clamp (where loads concentrate) with a deliberate return to more compliant tubing as you move toward the drops.
- Transition zones engineered to avoid stress risers—because abrupt changes in diameter can create the very durability issues standards are supposed to solve.
- Accessory friendliness—keeping round sections and common diameters where computer mounts, lights, and aero clip-ons want to live.
The result—if executed well—is a handlebar that feels calm over chatter, holds a line under sprint torque, and doesn’t demand you replace half your cockpit to participate.
Why riders should care: ride feel is not marketing fluff
Handlebars are one of the most influential touchpoints on the bike. Changing a bar can subtly (or dramatically) alter your perception of the entire frame. A bar that’s too stiff can make a fast bike feel nervous and fatiguing; a bar that’s too flexy can make a stable bike feel vague when you’re descending with intent.
That’s why this “31.8 + 35” framing matters. It isn’t about chasing a number; it’s about acknowledging that stiffness is not a universal good. What most of us want is appropriate stiffness—a measured response in the steering plane, with enough vertical give to keep the hands quiet over long distances.
For riders building modern all-road bikes—especially those running wider tires but still logging serious road miles—the cockpit becomes the final tuning fork. A hybrid bar concept could be a genuinely useful evolution if it preserves comfort while improving control under load.
Compatibility and the hidden cost of “upgrade” standards
Let’s be honest: the real reason some riders resist 35mm isn’t fear of stiffness. It’s fear of the domino effect. A bar swap becomes a stem swap. A stem swap becomes new mounts. New mounts become new lights. Suddenly you’re two clicks away from a full “front end ecosystem.”
If FAIR’s approach aims to bridge standards—either through thoughtful tapering, clever clamping interfaces, or simply maintaining usability for common accessories—that could lower the friction that keeps many riders locked into legacy parts.
And while we’re talking cockpit practicality: if you’re assessing any bar change, it’s worth refreshing the basics—torque, paste for carbon interfaces, and the right tool for the job.

The editorial verdict: a sensible direction—if the execution is honest
I’m receptive to FAIR’s “best of both worlds” thesis because it addresses real rider priorities instead of pretending every cyclist is a criterium sprinter or a downhill racer. But the difference between a meaningful cockpit innovation and a slogan is in the details: wall thickness, taper length, fatigue testing, and whether the bar’s stiffness curve actually matches its intended use.
What I want most from FAIR isn’t a new standard for the sake of it. It’s a clear explanation of what they tuned for: where stiffness increases, where compliance returns, and how the bar behaves under real-world inputs—seated climbing, rough tarmac, loaded gravel turns, and hands-in-drops braking.
Because the “result” of adding 31.8 to 35 shouldn’t be confusion. It should be choice without punishment: better performance for those who want it, and better comfort for those who need it, with fewer compatibility traps along the way.
FAQ
What is the result when you add the 31.8 handlebar standard to the 35 handlebar standard?
In practical terms, you’re aiming for a hybrid bar concept: stiffness and support where the clamp loads are highest (a “35-like” benefit), while preserving the comfort, ergonomics, and broader compatibility many riders associate with 31.8mm cockpits.
Is 35mm always stiffer than 31.8mm?
Not always. Diameter is only one variable. Layup, wall thickness, material, and bar shape play huge roles. Some 31.8 bars can feel stiffer than certain 35 bars depending on design intent.
Will a hybrid-style bar fit my current stem?
That depends on the specific clamp diameter the bar requires. Even if the bar is “inspired by both,” it still needs a single stem clamp interface. Confirm the clamp spec before buying.
Can a stiffer bar reduce fatigue?
Sometimes—if it improves steering accuracy and reduces the micro-corrections you make to hold a line. But excessive stiffness can increase vibration transfer. The best bars balance precision with damping.
What’s the most important thing to get right during installation?
Torque. Use a calibrated torque wrench and carbon paste where appropriate, and follow the bar and stem manufacturers’ specifications to avoid slipping or damage.
