The Cutlass has been completely rebuilt from the ground up for 2020. Constructed using a premium unidirectional carbon weave, but with an updated layup schedule and forming process, we continue to focus on strength and reliability as our priorities.
The 2020 Cutlass is one of the strongest carbon bars on the market today, going well beyond ISO standards. It passes the renowned Zedler Institute's most rigorous tests, including multi-load fatigue, max strength and end of life.
The 2020 Cutlass is now 800mm wide with backsweep increased to 9°. It continues to come in the classic 25mm rise but we’ve also added a 35mm version for those who want a little more lift up front.

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.
