No discipline is as broad as the “Enduro” segment. The Bikes used here are true all-rounders which can used on the big all day rides to DH level bike park excursions. And that’s what the Black One was built for!
The Black One is for the rider who pushes hard on their aggressive trail/enduro bike and needs stiffness, strength and responsiveness to match. Reverse built the Black One stem to be durable, create quick handling and with a wide clamping to provide stiffness while running 760-800 mm+ handlebars.
This stem was tested in the toughest fatigue lab test available. Even after hundreds of thousands of load changes in the lab, this stem could not be brought to its limits. In order to take even more load away from the handlebar, Reverse has developed the “Stress Reduction Clamping” (SRC) technology. The most stressed areas are at the transition between stem and handlebar. Especially at the lower gap from the clamping area where there are large loads.
The SRC-Technology prevents the normally shown notch effect in this area of concentrated stress because the gap that creates a sharp edge that could crush or indent a handlebar. The gap only exists at the upper clamping area which is essential for the clamping effect.
This technology allowed Reverse to create a nearly 360° clamped handlebar with an optimized load transmission and reduced notch effect. Even in the laboratory tests this benefit is clearly demonstrated. Especially for carbon bars Reverse recommends this.
With its "length" of 35 mm the Black One stem is the perfect choice for modern frames with their long top tubes / reach. Even with a clamping diameter of Ø 35.0 mm, the Black One Enduro is with just 130 g still the lightest stem on the market in its class!
