CARBONJACK 29”
Design & Innovation Award
WINNER 2021 CATEGORY MTB
“In many ways, the Antidote Carbonjack 29” is an exceptional bike. The most unique aspect of the carbon frame, which is made by hand in Poland, is the distinct visible carbon finish. But the small brand is also setting benchmarks with the design of the bike, combining a futuristic look with a high level of functionality. Thanks to the low-slung top tube, the bike offers a huge amount of freedom of movement. The balanced geometry is perfectly tuned for high-speed riding. Paired with the first-class Öhlins suspension and Antidote’s patented suspension, it results in a very capable enduro bike. The bike communicates precise feedback from the ground without overwhelming the rider. The Antidote Carbonjack 29” isn’t just a beauty, it’s also incredibly fast and a worthy award winner!”

GEOMETRY
“Golden Ratio Geometry” is the best overall geometry that we have ever designed. Why? Because the proportions between the front and rear triangles are most effective for the type of riding the Carbonjack is designed for. Our special balance distribution between the „Front Center” to „Chainstay” means better rider mass distribution, it doesn’t matter whether you are climbing or descending. The new Carbonjack geometry gives the rider confidence to progress.

Ohlins TTX 22M Custom (regular doesn’t match), Fox Float X2, DVO Topaz T3 Air

FDS SUSPENSION
- Pedalling efficiency with no feedback
- Superb small bump sensitivity
- Excelent traction during technical climbs
- Progression giving place to abuse
even on downhill tracks - Inline shock compression
UNIQUE SHOCK MOUNT
- Floating shock design
- Easy acces to settings
LOW CENTER OF GRAVITY
- Better cornering
- More control on ground and in the air
DAMPER ASSEMBLY
Through 90 degrees damper rotation, we have
obtained seamless, easy access to adjustment.

Equipped with 150 mm travel, slack geometry and short rear carbonjack gives the rider perfect balance while blasting down the trails. An upright seat tube angle and pedal efficient suspension makes climbing easy, giving you even more energy for fun parts!
Our floating damping system is patented. No shock mounts in the front triangle or swingarm means better stress distribution. A simple and effective suspension design with unique shock access combined with lightweight and aggressive geometry will improve your riding skills dramatically, before you realize it!
REVIEWS & TESTS
The Antidote Carbonjack 29 is a unique bike both because of its eclectic look and particular handling. While it proved to have an authentic character, this only comes to life on fast descents. The quality of workmanship and the details on the handmade carbon frame testify to the painstaking attention to detail and perfectionism of the small brand. If you’re looking for a unique and capable bike, the Carbonjack is a great option. The first scratch on the beautiful frame will hurt a lot though!
Mit dem Antidote Carbonjack 29 zeigt die polnische Manufaktur, dass äußerst hochwertige Carbon-Verarbeitung auch im kleinen Maßstab und in Europa gut funktioniert. Das Rad ist exzellent verarbeitet und vor allem optisch ein Leckerbissen für alle Kohlefaser-Fans. Im Einsatz giert es trotz moderaten 150 mm Federweg am Heck vor allem nach schnellen Strecken und überzeugt hier mit einer hohen Laufruhe sowie einem exzellenten Fahrwerk.
La première impression à son guidon est celle d’un mini-vélo de descente et elle est vite confortée lorsqu’on enchaîne les premières sections à bonne allure, mais des sorties plus tranquilles ont également montré que le Carbonjack savait se faire doux et “léger”. C’est un très bon vélo polyvalent pour celles et ceux qui s’amusent plus dans les descentes que dans les montées et, s’il sera toujours plus à l’aise sur les gros chocs et à bonne vitesse, il ne se montrera jamais encombrant dans les autres situations.
Super-fast on the descents, with a smooth ride feel that still manages to keep you connected with the trail. Beautifully sculpted frame and superb components. Pedals well too.
