TARVO

The lightest
Enduro

The lightest Enduro frame. Engineered and manufactured in Germany.

When we took the first frame from the mould, we instantly knew: our vision takes off swimmigly. From the start it was our dream to make the TARVO the lightest Enduro bike of the world. It's consequently designed with performance, durability and weight in mind. Its production quality is so high, it looks great raw out of the mold. On the trail, the TARVO is absolutely thrilling: You feel the feedback of the progression and instantly the bike is pushing you into the next berm. It's direct, precise and damn fast.

Functional Lightweight – the TARVO's Concept

With our bikes, performance and riding fun are the top priority. In addition to their weight, the geometry and the suspension system form the basis for every bike. Our vision was not only to make the TARVO the lightest Enduro, but first of all to design a fast and easy to control bike. We didn't just build our tested frame concept out of carbon, we completely redesigned everything. We use the advantages of the material in a way that you can really feel: The TARVO is sturdy but still lighter then anything that we have built before. The frame weighs almost a kilogram less than our already light aluminium frames. The kinematics are very progressive, just like with our other bikes. This is achieved with a suspension system based on a flex pivot and a rocker arm. The directional stiffness of the carbon is used to form an elastic joint which is lighter, free of play and requires no maintenance. The TARVO is manufactured in a high-quality autoclave process as a monocoque without glue joints. The result is a highly functional frame that is extremely light, yet low-maintenance and extremely sturdy.

Geometry

For the fun of downhill riding, the TARVO is designed with a flat steering angle of 64 degrees. The balanced ratio of reach to chainstay length ensures a lively and playful character. The short seat tubes and the full retractability of the seat post allow every rider to choose between several sizes - depending on their preference for a longer or shorter bike. For the TARVO we adjust the chainstay length, seat angle and bottom bracket height to suit each frame size perfectly. Size 165 has a bottom bracket that is 5 mm lower, as we recommend shorter 170 mm cranks for shorter riders. The chain stay length of size 165 is 430 mm and increases continuously up to 444 mm for size 195. For the larger sizes we designed the seat tube a little steeper to get more pressure on the front wheel. To give a starting point for the size selection, we name the sizes according to the typical rider sizes: 165, 175, 185 and 195.

Suspension System

Progressive Suspension System

The TARVO provides a very progressive suspension system with a minimum of rocker arms and bearings. For the first time, a bike with 160 mm suspension travel is designed as a flex pivot and achieves a progression of 55 percent. More significant than the overall progression is the progression from the sag point to the end of the travel, which is 34 percent. This is made possible by the optimal choice of pivot points, so that the flex pivot is hardly stressed and an optimal durability is achieved. The progressive kinematics allow the use of both air and coil shocks.
Anti Squat

Size-specific Anti-Squat

Pedalling efficiency is generated to a large extent by a well-fitting anti-squat value. The value depends on the kinematics of the bike and the height of the rider's centre of gravity. To always achieve the optimum anti-squat, we adjust the position of the pivot points for each frame size and the expected height of the centre of gravity. The blue graphs show the anti-squat values for the four frame sizes depending on the rear cog (x-axis). For comparison, the grey curves show the values for a non optimized system. It is easily recognizable that the blue lines are closer to each other, especially for low gears.
Anti Rise

Anti Rise

The anti rise value determines how the suspension behaves during braking. A value around 100% is considered the optimum, since the suspension behaves neutrally at this figure. This means that the application of the brake has no disturbing influence on the suspension system. The size specific optimization results in four almost identical blue curves, that appear as one thick blue curve in the diagram.

Features

Lightweight Construction - the Basic Conditions

The TARVO is more than just light: it meets strength requirements that far exceed the norms. For two decades now, we have been working together with EFBE Prüftechnik, where the TARVO underwent the most demanding load tests. The result of these tests and practical trials is the approval of the bike for use according to the highest category (5) of ASTM F2043-13, making the TARVO a tested and safe lightweight construction according to the latest standards. The frame is laminated by the carbon-construction experts at All Ahead in Würzburg. We are so convinced of the quality and the result that the TARVO carries a 5 year warranty.
Lightweight Construction
Autoclave Process

Autoclave Process

In addition to the quality of fiber and matrix, the manufacturing quality is decisive for the lightweight construction potential. Only if the prepreg layers are optimally pressed together, a load-bearing structure can be created. This requires craftsmanship and care as well as the masterful control of the manufacturing process itself. In the autoclave process, the material undergoes strong compression due to the applied pressure. At the same time, a vacuum is created in the laminate to remove residual air. Careful process control using measurement data allows the quality of each individual component to be verified. The high processing quality makes it possible to reduce the amount of material to the required minimum.

Monocoque Frame

The front and rear of the frame are each produced as a whole in one mould. Due to the monocoque design, it features a consistent laminate structure without any weak points. Heavy joints where material is doubled up are completely eliminated.

Responsibilty and Ecology

Responsibilty and Ecology

In choosing our partners and suppliers, we attach great importance to good conditions, both in terms of the environment and conditions for employees. That's why we prefer suppliers from free democratic countries. For the TARVO, this means: the carbon fibres come from Japan. The processing into preimpregnated fibres is done in Italy. The frame is laminated in Würzburg at All Ahead in compliance with environmental standards. The colored frames are painted in Hagen, Germany. Finally, all frames are assembled, tested and, if desired, assembled into complete bikes in Dortmund.
