At Escapa, we present the SRAM Force E-Tap AXS Shifters + Hammerhead Karoo Upgrade Kit, designed for the performance cyclist who understands that every watt and every decision counts. The integration of the SRAM Force AXS E1 groupset with the Hammerhead Karoo 3 bike computer isn’t just an upgrade—it’s a redefinition of the cockpit.
The SRAM Force E-Tap AXS Shifters + Hammerhead Karoo Upgrade Kit is the perfect symbiosis of mechanical precision and navigation intelligence, creating an ecosystem of control, customization, and confidence unlike anything before. This combination of elite drivetrain components and a smart navigation brain redefines performance on the road.
The SRAM Force eTap AXS HRD system is the performance core of this kit, designed to deliver maximum control, comfort, and safety. Its focus is on completely redesigned ergonomics, superior braking control, and the wireless customization that defines modern road cycling. These improvements ensure a lighter, more comfortable, and more powerful riding experience, eliminating fatigue and allowing the rider to focus solely on the ride.
• Optimized Lever Ergonomics: The new lever shape is designed to accommodate a wider range of hand sizes, a direct result of more than four years of rider feedback. This translates to a more secure and comfortable grip, significantly reducing fatigue on long rides.
• Powerful and Precise Braking: The system enables “one-finger braking” thanks to stiffer calipers. This increased stiffness reduces system flex, ensuring that braking force is transferred directly to the pads for superior modulation and
exceptional stopping power, rather than being lost to component flex. The result is superior control with less effort and no hand fatigue during extended descents.
• High-Performance Materials: The use of carbon brake levers not only reduces the overall weight of the assembly (“lighter weight”) but also improves tactile feedback and dampens road vibrations, helping to reduce rider fatigue on uneven surfaces.
• Intuitive eTap Shifting Logic: The eTap wireless electronic shifting system is renowned for its simplicity and reliability. Its operating logic is clear and intuitive, ensuring precise and rapid gear changes in any situation.
• AXS Customization: The AXS platform allows for easy configuration and customization of shifting behavior via an app. This gives the rider the power to tailor the system to their specific riding style.
• Bonus Button: The shift levers include an additional button that can be configured to control ANT+ devices (such as the Karoo 3 bike computer itself) or to function as an auxiliary shifting option, adding an extra layer of functionality.
• Reach Adjust: The ability to customize the reach of the brake lever is essential for ensuring a perfect fit for any hand size, improving both comfort and safety.
• Bleeding Edge Technology: This technology simplifies the process of bleeding hydraulic brakes, making it faster, cleaner, and more accessible for routine maintenance.
