The Pedal Kickback Revolution: Is DT Swiss and Others Changing Mountain Biking Forever?
The mountain biking world is buzzing, and the source of the energy is pedal kickback. It’s a phenomenon that’s been a thorn in the side of riders for years, and finally, major players like DT Swiss are stepping up to address it. Their “Degrees of Freedom” upgrade kit signifies a significant shift, moving this tech from the fringes to the mainstream. But what exactly is pedal kickback, and why is it suddenly such a hot topic?
Understanding the Problem: What is Pedal Kickback?
Imagine you’re bombing down a trail, and suddenly, your pedals feel like they’re fighting back. That’s pedal kickback in a nutshell. It occurs primarily when your rear suspension compresses, causing the distance between your rear axle and the bottom bracket to change. This chain growth pulls the chain backward, rotating your cranks and making your pedals “kick” against your feet.
This issue is most pronounced on bikes with longer travel and specific suspension designs, like those using a high pivot. These designs often use an idler pulley to mitigate chain growth, improving the feel of the bike, especially during high-speed compressions.
Did you know? Pedal kickback can not only be uncomfortable, but it can also throw off your balance and rob you of valuable control, especially in technical terrain.
DT Swiss’s Solution: Degrees of Freedom Explained
DT Swiss’s “Degrees of Freedom” (DF) system offers a clever solution. Rather than a direct engagement, the hub allows for a degree of free movement before force is transferred to the pedals. You can choose between 0, 10, or 20 degrees of “freedom”. This means when your suspension compresses, and the wheel moves, the hub can move those specified degrees before engaging with your pedals. It’s a smart approach to reduce that kickback sensation.
The great news is that the DT Swiss system is backward compatible with existing Ratchet DEG freehub systems, including their popular 240 and 350 hubs. Upgrade kits are now available, offering an accessible path to anti-kickback tech for existing DT Swiss hub owners. An eMTB version is also in the works, limited to 0° or 10°.
Beyond DT Swiss: Other Players in the Anti-Kickback Game
DT Swiss isn’t alone. The demand for solutions has spawned innovation across the industry, with different approaches to achieve the same goal: a smoother ride.
Williams Racing Products offers “Zero Drag” kits that fit DT hubs, showing the market’s demand.
O-Chain (now under SRAM) and Rimpact take a different approach by mitigating kickback at the chainring. This allows for movement between the chainring and the cranks, and allowing the chain to pull the chainring backwards slightly without the force being transferred to the pedals.
e*thirteen offers its Sidekick hub, which uses a proprietary freehub mechanism to disengage the rear wheel from the drivetrain while coasting, creating an adjustable “deadband” to isolate the chain movement.
Who Needs Anti-Pedal Kickback Tech?
This technology isn’t for every rider. The primary target market is gravity-focused riders, particularly downhill and enduro racers and riders who prioritize descending performance.
Pro Tip: If you’re a cross-country or trail rider who values immediate power transfer, you might prefer a high-engagement hub over an anti-kickback system.
The Future of Pedal Kickback: What to Expect
The adoption of pedal kickback mitigation technology is still in its early stages, but the momentum is undeniable. Here’s what we can expect in the coming years:
- Wider Adoption: More major brands are likely to release their own anti-kickback systems, driving down costs and making the technology more accessible.
- Refinement: Expect further innovation, with manufacturers continuously refining designs for improved performance and reduced complexity.
- Integration: As suspension designs evolve, we might see anti-kickback systems integrated directly into frame designs, optimizing performance from the ground up.
- Specialization: Different levels of pedal kickback mitigation will be offered to cater to various riding styles and preferences.
- eMTB Application: eMTBs, with their added weight and power, are a natural fit for this technology, and we’ll likely see more eMTB-specific solutions emerge.
FAQ: Your Questions Answered
Q: Does anti-pedal kickback technology affect pedaling efficiency?
A: Yes, to a degree. The amount of free movement can mean a slight delay in power transfer, especially when pedaling hard. However, the benefits in descending often outweigh this.
Q: Can I upgrade my existing mountain bike with an anti-kickback system?
A: Yes, depending on the system. DT Swiss, for example, offers upgrade kits that are compatible with their existing hubs.
Q: Is anti-pedal kickback technology worth the investment?
A: If you are a gravity-focused rider, the improved ride quality and control can make it a worthwhile investment.
Q: Will this technology eliminate pedal kickback completely?
A: No, but it will significantly reduce the effect, making your ride smoother and more controlled.
The pedal kickback story is far from over. It’s an exciting time for mountain biking, with innovation focused on enhancing the rider experience. As more brands get involved and technologies evolve, expect to see the anti-kickback revolution continue to shape the future of mountain bike performance.
