Standard rear derailleur setups rely on a factory B-link that introduces subtle lateral flex, resulting in delayed electronic shifting response under intense riding loads. This premium Italian upgrade completely bypasses the stock B-link, creating an ultra-rigid, direct-mount connection between your high-performance Shimano rear derailleur and any modern UDH-standard frame.
Engineered and manufactured 100% in Italy from aerospace-grade AL7075-T6 aluminum, it delivers an unparalleled stiffness-to-weight ratio while simplifying rear wheel removal. Built to withstand elite racing conditions, it features a engineered sacrificial breakaway point to protect your frame from catastrophic damage during severe crashes.
FEATURES
AL7075-T6 CNC Structure
Maximizes structural rigidity at the rear dropout while maintaining an incredibly low profile.
Direct Mount Integration
