OSX 35

$125 CAD

The OSX35 is built off the foundation of the classic, standard setting OSX, with a 35mm stem-clamp diameter.  It features our benchmark 8° / 5° bend and usweep geometry, a full 800mm width (which can be reduced), and comes in both 25mm and 35mm rise options.

The OSX35 features a balanced flex vs stiffness that gives the rider amazing feel and control while being impressively durable both in long term fatigue situations, as well as impact resistance.  It's the result of years of refinement and iterative improvement. By refining the shape, and utilizing variable butting, high grade alloys and advanced heat treatment techniques, we have increased the fatigue life to many times the ISO industry standard. So much so, that we’ve seen fatigue test results reach over 1 million cycles.  This creates not only a strong, reliable bar, but one that feels great with a balance of flex and control for the best ride possible!

  • 35mm clamp
  • 8° bend / 5° upsweep
  • 800mm wide (can be reduced)
  • 7000 series alloy provides optimal strength to weight.

7050 Series Aluminum

We use aerospace grade aluminum to achieve our required properties of strength and toughness, with added resistance to stress and corrosion.

Advanced Heat Treatment

Heat treatment gets thrown around a lot, but most of the time the word consistency doesn’t come along with it. Depending on the batch an individual bar might be subjected to vastly different temperatures during the process. HTX ditches the disparity and provides uniform, quality heat treatment on every single bar.

Refined Geometry

By increasing the tapered sections and using a larger radius we have inherently built more strength into the shape of the OSX.

Variable Butting

Varying the wall thickness of the bar allows us to add strength where it’s needed, and keep the weight down in less strategic areas. The OSX has 7 different butting locations.


Zedler is known within the cycling industry as the foremost test institute for bicycle frames and components.  Based in Germany, they have been making test equipment and conducting third party testing for 30 years.  In the cycling industry, the most common testing standard for bicycles and components, the EN/ISO Standard, is decades old and not really relatable to the kind of loads that modern components see.  For this reason, Zedler have created test standards that test up to the EN/ISO standard and then far beyond this, to simulate the most extreme scenarios that today’s components will see in use. 

Part of the latest evolution of our handlebars was to ensure that all of the design improvements we’ve made translated in to real-world, measurable increases in performance.  Part of this was to build our own test lab and equipment, where we can test prototype and also production batches of handlebars for safety and performance.  We also sent our new carbon bars to Zedler to test them to their high industry standard, which allows us to benchmark them against other products available on the market.

The tests in question relate to the fatigue life of the bar, and are designed to simulate the loads that the handlebar will see over its entire service life. These include a precisely designed and controlled sequence of loads on the handlebar in all directions, and also a ‘Push-Pull Test’ which as the name suggests, pushes and pulls on the bars with a high force, in the middle of the test. In the real world, this could relate to landing a large drop to flat after already riding the bar for a few years.

Both the Cutlass and BZA passed the highest test standard available from Zedler, the ‘Advanced Plus’ test. Both handlebars were intact at the end of these tests, and we stopped ‘End of Life’ testing when it became clear that it may take many more rounds of testing to see a failures from the bars.

Dope bars

Great bars, rise is just right for me. And they look awesome

Xavier H.
excellent bars

Awesome bars, I got those on my dirt jumper and I really like. Never went back!

So far so good

The allrounder

Perfect all-round bar, great balance between stiffness and flex and the angles/geo suit me perfectly. Just swapped these out from another brand's OEM carbon bar because I don't like the feel of carbon bars and these are amazing.

Great for bike parks!

Had the carbon Pivot bars that came with my Mach 6 ... Ride almost all park so wanted alloy ones, figured I'd ride the carbons for a few months though. Big mistake. Had a crash and they broke right at the brake. Killington Bike Park only had these OSX 35s so I didn't have a choice, but after riding hard on em for a week now, they're definitely something I'd buy again. They're the right width and have just the right combination of flex and stiffness. Plus they look sick!


Go to bars for my dirt jumper builds, haven't bend one. Solid!
