OSX

CHF 85

We've been making handlebars for over 20 years now and the OSX is evolved from our originial alloy handlebars.  It has a reputation for its proven combination of bend and upsweep that has been copied by countless others.  The OSX features a balanced flex vs stiffness that gives the rider amazing feel and control. These characteristics and geometry combined with an array of colour choices has made the OSX a popular choice for pretty much any discipline of mountain biking.

The current OSX is 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!

  • 31.8mm clamp

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.

Best in the biz

I rode my first set of purple OSX bars in 2013 and absolutely loved them. Fast forward 10 years and after trying several other cockpit setups I always come back to Chromag. OSX bars are strong, reliable, and light and Chromag always kills it with their beautiful finish and graphics, making any bike look baller. I strongly recommend these bars for DJ, DH, trail riding, or anything in between!

Standard to which others should be measured

Fantastic bars - I have been using these bars on a number of different DH and enduro bikes and they have always been top notch and I've never had a single issue with them. Would highly recommend these bars and the brand as a whole.

Best looking and feeling bars in the game

My first ever Chromag product was a black chrome OSX and it just felt right from the first minute. Several colours and bikes later it's still my go-to bar. The only thing left to desire is the resurrection of the black chrome colourway, I loved that first one so much I've hanged it on the wall.

They fit just right

I've been running these bars for 5 years now. I've tried a few other well-reviewed brands over that time as well, but they have only ever stayed on my bike for a couple of rides before I swap back to the Chromags.
The geometry of the bars works well for me, they have enough flex to not destroy my arms, and the finish holds up well.
All-in-all good bars that, to me, are worth the small premium over some of their competitors.
