Zedler Institut, Germany

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. 

testing

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.

key features

More than meets the eye, our bars are a carefully tuned piece of kit.

UCX Carbon Layup

Our UCX carbon layup has been refined with years of experience to result in a strong and reliable handlebar with great flex characteristics. The hand laid process gives us full control of the material thickness at all points along the handlebar. This gives the same result as the variable butting of our alloy handlebars, with material and strength where it is needed most.

ISO 4210

We test our handlebars to a far more rigorous standard than that required by ISO. We see this as part of our due diligence to create strong, safe and reliable products that our customers can trust.

Variable Butting

Variable butted wall thickness optimises strength in areas where needed, while maintaining flex for a great overall feel and optimised weight.

Bar FAQ's

Nowadays there are really only two bar clamp diameters, 31.8mm and 35mm. You should check your stem to see what you currently have.

If you are buying a new stem, be sure to match up the clamp size.

There is no real lifespan to our alloy bars, however if you've had a big crash it's probably a good idea to change your bar.

You should frequently inspect your bars for bends or signs of damage.

You absolutely can (and likely should) cut your bars down! They will still be covered under our warranty and crash replacement programs.

Remember to cut them down evenly on both sides.

Wrapping tape around the bar at the cutting location can limit chips, splinters etc. A carbon-specific blade is recommended however a regular hacksaw (we recommend 32tpi) can also be used – with care. Note that aggressive cutting can cause a carbon bar to splinter. Cut slowly.

This is the source of great debate. We can't really offer an exact rule other than to try and test what others have, and don't be hasty to cut too much off.

In short, start small!

Technically our carbon bars produce stronger test results, however they are more likely to pickup damage in a crash.

If you are the sort of person who doesn't like inspecting their bike after a crash and changing out parts as a precautionary measure, we recommend going with alloy.

You can read the full user guide here, but mainly make sure the clamping surfaces are clean, the stem faceplate is installed evenly, and always follow the torque specifications for the stem, grips and controls.

As a general rule, you should be able to move your controls by hand, after tightening.

Cutlass bars

These bars are light and stiff - love them!

Cutlass bars are dope

The stock carbon bars on my bike were super stiff and was getting a lot of forearm fatigue/pump. At the suggestion of the friendly and helpful Chromag staff I tried the Cutlass in a 35mm rise. Problem solved! Between the super comfy magic Chromag angles and the 31.8mm diameter I have a comfortable and precise ride.

Tough and comfortable

This bar replaces another Cutlass bar that I used on multiple bikes over the past 4 years. That Cutlass has been ridden for 6k miles on rocky trails with a few hard crashes thrown in. It is only being replaced as a preventative measure. The original bar isn't showing any signs of damage.

Cutlas Review

I recently switched from an aluminum bar to the Cutlas and I immediately felt more confident. The 9 degree back sweep puts you in the ideal riding position. These bars have a little flex to them which allows for a smoother ride resulting in less arm pump. I have always struggled with arm pump on long descents or race runs so these are a game changer for me. I look forward to putting these on all my bikes.

Nice bars

Replaced the flat bars on our two carbine fibre gravel bikes. Originals were too short and too heavy. These bars are attractive light and have the perfect combination of angles for what I wanted. Good value as well. I would buy them again in a heartbeat.

Primer build

Chromag’s customer service is always otop notch, keeping you informed every step of the process. I have nothing but great things to say about all my purchases with the company and would not hesitate to recommend their product to all riders who ask when I’m out for a spin.

Less vibration yet still stiff in a good way

Impressed with these bars so far on my hardtail. I ran Fu40 Chromag bars for about 4 years. Loved the ride and sweep of them, but they had a wee bit too much trail feedback. I then had We Are One da package bars/stem on my rig for about a year, but they were a little too flexy for my 185 lbs. I just found myself having a hard time holding a precise line in the fast technical riding. I’ve now been running the cutlass for a half a dozen rides and really dig them. A little more trail feedback than the Da Package bars/stem, but they’re stiffer in a good way allowing me to hold a line in spicy situations. Safety third! Good on ya chromag
