PATHSEEKER

A suspended gravel bike, where we have designed the suspension not as a mere copy of MTB solutions, but to meet the specific demands of its segment. Without hydraulics or complex systems, our solution offers the right amount of antisquat and reliable damping at an optimal travel range. The fork also takes on part of the work, ensuring smooth traction without unnecessarily absorbing pedaling energy. When designing the frame, we developed a composite using four materials: carbon fiber, flax fiber, basalt fiber, and bio-based resin, creating a truly ecological solution—one that works and offers unique advantages. By properly layering these materials and leveraging the characteristics of natural fibers, we have eliminated a significant amount of vibration, which traditional suspension cannot fully absorb.
PATHSEEKER represents a new dimension of material synergy. It’s dynamics without loss of comfort. Efficiency with the potential for fun. Sustainability that works and outperforms traditional solutions, shaping the future. This is a bike where you have everything you need and nothing you don’t. Just the right amount, taken from all the bikes in the world. And if you ever have to choose which bike to take to a deserted island, we’ll be confident in our recommendation: Antidote will open new, undiscovered trails for you.

NANO FLEX

NanoFlex is a proprietary suspension system designed by Antidote. There are several rear wheel suspension solutions for gravel bikes on the market, but our system stands out significantly. The key feature of this concept is the direct transfer of MTB suspension principles, meaning it has four pivot points and full lateral stiffness. Two of these points are virtually fixed—traditional pivot axles have been replaced with the flexibility of the chainstay tubes. The remaining pivots function through an eccentric mechanism placed in the front triangle, acting similarly to a cam pushing the shock absorber. The system integrated into the frame allows the components to rotate relative to each other, with the entire structure stabilized by an elastomer. The elastomer controls suspension travel and vibration damping. It is replaceable, enabling a full range of stiffness adjustments.

The suspension fork, on the other hand, is an integrated system combined with a carbon fork. It operates using either a spring or an interchangeable elastomer. A convenient lockout mechanism is located in the steerer cap. In the event of fork damage, the suspension-fork system can be separated for replacement or repair.

Nanoflex was created based on the individual needs of the gravel segment. It is not just a comfort buffer, as is the case with many such solutions, but has the features of a real system that would meet the requirements of mtb:

the suspension reacts to any type of bump – from small to the biggest impacts
the suspension works at any speed pedaling has no effect on the suspension
braking has no effect on the suspension
the rear triangle of the frame is rigid, does not move sideways
the suspension system is laterally rigid
all construction parts are easily serviceable (replaceable)
there is a progressive characteristic – the suspension hardens with increasing deflection, which prevents hard bottoming out
construction of suspension system is pretty light
the design is as simple as possible, while maintaining high kinematic parameters.
