A Front Derailleur Alternative That Delivers
Are you searching for a front derailleur alternative that offers the same functionality without the downsides? Look no further!

Here's what you gain:
? No Front Derailleur: Say goodbye to front derailleur hassles.
? Reduced Aero Drag: Embrace enhanced aerodynamics for a faster ride.
? No Cross Chaining: Enjoy improved efficiency with straighter chainlines.
? No Small Chainrings: Experience a 45% reduction in chain forces for superior performance.
How It Operates
Performance That Matters
When compared to a 1x setup, Classified minimizes cross chaining, adopts larger sprocket and chainring sizes, and reduces chain tension, crank, and hub bearing losses. Unlike a 2x system, the 0.7 hub ratio continues to utilize the large chainring upfront, leading to a 30% reduction in chain tension and fewer losses.
You'll find yourself using the Classified hub more frequently than a traditional front derailleur, minimizing cross chain losses. The hub exhibits negligible losses in the 0.7 ratio, expertly balanced by the big chainring and straighter chainline unique to Classified.
Furthermore, Classified hubs are built to outlast your bicycle's internal systems, requiring zero maintenance. Only wheel bearings are subject to wear, which can be effortlessly replaced.
Shift Under Any Circumstance
Classified stands out as the only system capable of shifting under load. Shift without holding back, even under intense power outputs of up to 1000 watts. Shift while coasting, back pedaling, or when stationary—the hub seamlessly completes shifts, ensuring faster, trouble-free gear changes.
Unlock Performance with Classified
By combining 2 gears with a standard derailleur setup, we provide a wide gear range and small gear steps you're accustomed to. Eliminating the front derailleur gives you the reliability and performance you've always craved.
Our mission is simple: optimize your drivetrain for peak performance. We believe in the potential of chain-based drivetrains but aim to eliminate their weakest link—the front derailleur. Classified offers a wide gear range and small gear steps, making it operate just like a traditional 2x-setup.
The gear ratio/set size of the Powershift hub (1:1 ratio in the virtual big gear and 1:0.686 ratio in the virtual small gear) is meticulously designed for flawless Powershifting.
Experience the future of cycling with the R50 Carbon Wheelset with Powershift. Upgrade today and transform your riding experience.
