THE DETAIL

Precise Wireless Shifting: Experience crisp, clean, and instantaneous gear changes without cables, offering unmatched responsiveness.
Integrated On-Board Battery: This bike uses a removable battery (BT-DN320 sold separately) cleverly protected within the derailleur's linkage, offering a sleek look and enhanced durability.
Crash Recovery Function: This function automatically absorbs impacts and returns the derailleur to its original position, significantly reducing the risk of damage during unexpected knocks.
Advanced Connectivity: This product features BLE (Bluetooth Low Energy) and ANT private connectivity for seamless communication with your setup.
Shadow ES Design: A low-profile skid plate design and optimised slant angle provide excellent ground clearance, reducing snags and impacts.
Enhanced Chain Stability: The Shadow ES system incorporates a dual-spring chain stabilising switch that, when engaged, drastically reduces chain bounce on rough terrain, maintaining a more stable drivetrain and improving shifting consistency.
Zero Maintenance & Consistent Performance: Designed for superior durability with no performance degradation over time, ensuring a hassle-free experience.
Optimised Chain Wrap: A unique dual-spring structure provides a tighter chain wrap, improving shifting security with a 70% increase in spring force, which firmly meshes the chain with the sprocket and prevents skipping, even as cogs wear.
Efficient Pulley System: This system features 13T solid pulleys and decreased derailleur tension, preventing high chain tension in low gears for smoother operation.
Premium Construction: It boasts a full carbon fibre outer pulley cage for weight savings, an alloy inner cage for rigidity, cold-forged wide alloy links, and four fluorine-coated link pin bushings for smooth movement.
