Details
When developing the Bergreif, the goal was to maximize the aerodynamic benefit of every gram. The result is a wheel weighing 1200 g, a weight normally only achieved by absolute specialists.
The combination of low weight and aerodynamics makes the Bergeif a wheel that is the best choice for most rides. Already on gradients of just 2%, it goes faster than deeper wheels. The lightweight rim also has a positive effect on handling: the wheel accelerates effortlessly, handling is lively and agile, and thanks to the low rim, crosswinds have little effect on steering..

Features
Maximized Aerodynamics for Every Gram
We chose the rim profile so that each additional gram of weight brings even more aerodynamic benefits than the previous one. A taller rim would be even more aerodynamic, but the aerodynamic gain per additional gram decreases. The weight is invested more efficiently elsewhere, for example in our Luftschneider cockpit.
Wind Tunnel Tested
We tested the Bergreif in the legendary GST wind tunnel. Compared to the significantly heavier DT Swiss ARC1400 with 55 mm high rims, they performed surprisingly well and came much closer to the aero specialists than other wheels in this weight class.
Well-Proven Components
When it comes to hubs and spokes, we rely on tried-and-tested components. DT Swiss 240 and 350 hubs are considered the most reliable on the market, offering durability and lightness.
DT Aerolite spokes are the best DT Swiss has to offer. They combine minimal weight with an aerodynamic cross-section. We opted for the classic version with a J-bend head, as our measurements showed that this contributes to a stiffer and more aerodynamic wheel.
Modern Rim Profile
With an inner width of 23 mm, we have maximized the width for 28 mm tires within ETRTO regulations. For a reliable tire fit, we use a rim profile with hooks that is optimized for use with tubeless tires.
