Build Your Dream Enduro Machine: The Antidote Carbonjack 29 Frameset - Ex-Display showbike
The Antidote Carbonjack 29 frameset is a masterpiece of design and engineering, crafted by hand in Poland for the rider who demands uncompromising performance and a truly unique aesthetic. Far from a mass-produced product, this frameset is a testament to meticulous craftsmanship and a passion for pushing the boundaries of mountain bike technology. It provides the perfect, high-performance canvas for your ultimate custom enduro or all-mountain build.
With its striking raw carbon finish and futuristic lines, the Carbonjack isn't just a frame—it's a statement, offering a ride quality that is as impressive as its looks.
The Antidote Carbonjack 29 frameset is the definitive choice for the rider seeking a bespoke, high-performance platform that stands out from the crowd. It’s an elite-level frame with a unique soul, built for pure riding.
Handmade Carbon Fibre Construction: Each Carbonjack frameset is built by hand in Antidote’s Polish factory, using a unique composite blend that includes Vectran fibres for enhanced strength and superior impact resistance. This results in a frameset that is both lightweight and incredibly durable, backed by the integrity of a small-batch, artisanal process.
Patented FDS Suspension System: At the core of the frame is Antidote’s proprietary Floating Damping System (FDS). This unique 150mm travel platform compresses the rear shock from both ends, creating a sensitive and highly efficient suspension feel. The shock is mounted perpendicularly within the frame, ensuring seamless access to all your damping and rebound adjustments while keeping it shielded from trail debris.
Balanced Enduro Geometry: The Carbonjack 29 is designed to be a versatile and capable all-rounder. With a well-balanced 65-degree head tube angle and a solid 450mm chainstay length across all sizes, it offers stability at speed without sacrificing a playful and agile feel on the trail.
Modern Standards & Smart Features: The frame is designed with practicality in mind, featuring a traditional threaded bottom bracket (TBB) for easy maintenance and long-term durability. It comes with integrated chainstay and downtube protection, internal cable routing with guided tubes for easy installation, and is compatible with Boost 12x148mm rear axles.
Unrivalled Attention to Detail: Every element of the Carbonjack is carefully considered, from the raw carbon finish to the CNC-machined anodised links and titanium bolts. With ample space for a water bottle in the front triangle, this is a frameset that combines exotic performance with everyday usability.
