Hot News: Easton releases Haven 35 oversized handlebars and stems

Upsized 35mm diameter strengthens, stiffens trail- and enduro-focused line

Components News

The new Easton Haven 35 Carbon bar is available in hi- or lo-rise and in four accent options—black, red, blue or green.

Easton Cycling has released its new Haven 35 range today—a system of handlebars and stems with a 35mm clamping diameter, that’s said to be stronger and stiffer than the conventional 31.8mm interface. Easton introduced the oversized standard a couple years ago on their Havoc gravity line to address the diminishing stiffness that ever-growing handlebar widths created.

Now the company has migrated the concept to their Haven line of trail components, offering the 35 on 750mm-wide bars in both carbon and alloy in 20mm low- and 40mm high-rise versions. The aluminum Haven 35 stem comes in lengths from 40, 50, 70 and 90mm.

“Our market-leading Havoc 35 bar and stem have proven the benefits of the 35mm system,” said Easton Cycling Brand Manager Dain Zaffke. “Now our popular Haven line is evolving in the same way—the result is a handlebar that’s wider and stronger without compromising weight or stiffness. Not to mention, we now have more options than ever before with bold colors—two rise options and four different stem lengths.”

Haven 35 aluminum bar is available in hi- or lo-rise and in three colors—black, blue or green. The Haven 35 stem is designed for both the carbon and aluminum bars.

At 750mm wide, the Haven 35 Carbon gains only 10 grams from the previous 711mm wide generation, but makes big gains in strength and ride quality, according to the company. Easton utilized a premium blend of ultra tough composite material that’s ride tuned to balance stiffness and damping. Both carbon and aluminum bars maintain virtually the same weight as their predecessors while gaining almost 40mm of width—a feat the company says is only possible because of the the 35mm bar diameter and the use of its vaunted TaperWall butting process.

    Can someone please explain from a physics perspective how it is possible to increase the lumen and width of a hollow bar while increasing stiffness and maintaining the same weight?

    It seems to fly in the face of logic. If if is simply a matter of superior materials, couldn’t the same thing be done on the previous standard instead of introducing a whole new size for us all to buy?

    • Eznitram says:

      Increasing the diameter means you can have thinner walls, less material and therefore less weight. That’s simple mechanics. That’s why our aluminum frames got fatter yet lighter over the past years. I don’t think the effect alone is enough to increase width and still save weight, so I guess you’re correct, the rest is improved materials.

  • Cracker4942 says:

    If it ain’t broke, reform it, redefine it, remake it, tout it, sell it – I got sucked into 31.8 mm and having learned my lesson (ie there is no discernible difference), I see no need to venture further. Do they really expect us to believe that this is a limiting factor for any ride ?

  • JRT says:

    Easton’s new Haven 35mm carbon bar is exactly what I had been looking to buy, but wasn’t finding. But the stem appears to be a half-baked design.

    It would seem that Easton’s model year 2014 Haven 35mm stems are intended to be used with Easton’s model year 2014 Haven 35mm carbon fiber handle bars; but there is little evidence of that in the design of the stem aside from the ~35mm diameter bore through the clamps to hold a 35mm handle bar. The stems have no markings or geometric features to align with the indexing marks printed on the handle bars. The stems have relatively small clamping surface area, and that will concentrate clamping stresses into a similarly small region of the carbon fiber handle bars, creating stress risers near the boundaries of the interface. And the finish seems similarly poorly thought through, with the stems finished in a gloss sheen that is a poor match to the matte sheen of the finish on the handle bars. Bad design is just that.

      JRT- We’ve been riding the 35 Haven for a couple months now and would have to say that in terms of performance and stress dispersion, you’re completely wrong about the Haven stem. The stem employs Easton’s TopLock features ( in which you tighten the top side bolts all the way and then do the lower bolts to the recommended torque setting. This system is designed to work with the curved opening on the faceplate which is purposely designed to maximize contact area and distribute stress while keeping the weight low. That curvature also helps prevent straight-line stress risers that other stems create–the opposite of what you describe. We’ve seen Easton’s torture testers in these videos in person for fatigue ( and impact testing (, as well as the numbers for competing bars and think these guys really know what they’re doing.
