What It Is
This isn’t just a derailleur—it’s a transmission system that rethinks the very bond between cassette and drivetrain. By mounting directly onto your wheel axle (yes, that axle), it locks into both sides of the frame like a mechanical fist. The result? A connection so rigid, so precise, that every shift feels like a direct neural link from your thumb to the trail.

What It Does
🚀 Hangerless Full-Mount Attachment – Say goodbye to bendy, breakable hangers. This beast clamps straight to the axle, turning your frame’s weak spot into its strongest anchor.
🌀 Magic Wheel Pulley – Rocks, mud, twigs? Bring ’em on. The lower pulley keeps spinning even when debris tries to jam it up. It’s like a self-cleaning oven, but for your drivetrain.
⚡ Overload Clutch – Smash into a rock? The clutch gives way gracefully, then snaps back like nothing happened. Your derailleur survives. Your race continues.
🔧 AXS Pairing & Setup – Same intuitive, foolproof procedure you already know. Pair it in seconds, forget about it for months.

This is the lightest, strongest, most unshakeable transmission derailleur ever bolted to a bike. It shifts with surgical precision, survives apocalyptic impacts, and weighs less than a water bottle. If you’re not racing with this, you’re racing against it.
