The CELOS pioneers modern geometry: slack front and steep seattube. Handmade in Germany

“The CELOS surprised me totally, because it is not only fast but also super agile! The riding position is impressively efficient, so that you want to accelerate permanently, even uphill. The smallest steering impulses are immediately implemented by the CELOS, so that I can direct it effortlessly, which is perfect for my playful riding style.”

CELOS - The Concept

The CELOS is our definition of the ideal short-travel bike: agile, playful to ride and efficient. For Alexander Kopp, it is the ideal bike for ultra-endurance races like the Silk Road Mountain Race; for us, it is the fastest bike for the after-work ride. The frame is built as a seamless monocoque from the highest-grade prepreg in an autoclave process, which makes it extremely light. The latest SUPERLIGHT layup version includes practical features such as the large storage compartment and the tool mount. The CELOS features durable bearings and is based on our robust frame platform, approved for ASTM Category 5: by swapping the rocker, it can be converted into an ASCO, CINTO or TARVO. You can configure your bike or frameset individually online. We are happy to advise you by phone, by email or in person in Dortmund, where you can also test ride all our bikes. To ensure this service and the quality of our frames, we limit the CELOS to 100 units per year.

CELOS

Geometry

Recently, slacker head angles and steeper seat angles have found their way into cross-country, too. The CELOS is one of the first short-travel bikes to consistently embrace this approach. The result: a bike that is faster and easier to control on descents. On climbs, the steep seat angle puts you in an efficient riding position for optimal power transfer. The chainstays grow with the frame size. Each size is named after the typical rider height, e.g. 170 for riders from 165 to 175 cm. Thanks to the short seat tubes and the wide variety of available seatpost lengths, up- and downsizing according to personal preference is easy. Forks with 130 mm of travel are also compatible, making the seat and head angles approx. 0.5 degrees slacker.

Suspension System

Progressive Suspension System

With its highly progressive suspension system, the CELOS has another unique feature among short-travel bikes. The suspension responds very sensitively at the beginning of the stroke and generates plenty of traction. From the sag point to the end of travel, the rocker provides 32 % progression, continuously increasing mid-stroke support. This effectively prevents bottom-outs. With a 55 mm stroke shock, rear wheel travel increases to 130 mm. The CELOS uses our proven Flexpivot: instead of a heavy pivot near the dropout, the necessary movement is fully elastic and therefore maintenance- and friction-free.
Anti Squat

Size-specific Anti-Squat

The anti-squat value describes the pedaling efficiency of a bike very well. In theory, 100 % corresponds to neutral pedaling behavior. In practice, values slightly above 100 % have proven to be optimal, since other influences besides inertial forces shape the overall impression. Excessive anti-squat values lead to a noticeable stiffening of the rear suspension when pedaling and reduce grip and comfort. To always achieve the optimum anti-squat value, we adjust the position of the pivot points for each frame size. The blue curves show the anti-squat values for the four frame sizes depending on the selected gear. For comparison, the gray curves show the values that would result without size-specific adjustment. It is clearly visible that the optimized curves are closer together and practically identical in the low gears.
Anti Rise

Anti Rise

To make full use of the CELOS's suspension travel under braking, the rear end must not stiffen when the brakes are applied. This behavior is described by the anti-rise value. Values slightly below 100 % – i.e. a slight softening of the suspension – are optimal for maintaining grip. Thanks to the size-specific optimization of the swingarm pivot, which is decisive for anti-squat, the blue curves are practically identical for all frame sizes.

Geometry

The geometry of the CELOS supports the rider with an efficient riding position and makes it easier for him to control the bike. The steep seat angle in combination with the generous reach results in an optimal top tube length. We recommend matching stem lengths around 50 mm. For riders taller than 185 cm we recommend about 60 mm. The steering angle of just over 66 degrees and the growing chainstays guarantee agile and safe handling. The naming of the sizes corresponds to the typical rider size. Up- and downsizing according to personal preferences is possible due to the short seat tubes and the variety of available seatpost lengths.

Progressive Suspension System

Leverage ratio With its highly progressive suspension system, the CELOS has a unique characteristic in the field of downcountry bikes. The suspension is sensitive at the beginning and generates a lot of traction. From the sag point to the end of travel, the system generates 32 % progression and thus increases mid stroke support continuously. Bottom outs are effectively prevented. If a damper with 55 mm stroke is used, the suspension travel at the rear increases to 130 mm. The CELOS uses our proven Flexpivot, which replaces a heavy link near the dropout. The fully reversible deformation is maintenance and friction free.

Size-specific Anti-Squat

Anti Squat The anti-squat value describes the pedaling efficiency of a bike very well. In theory, 100 % correspond to a neutral characteristic. In practice, values above 100 % have proven to be optimal, since other influences besides inertial forces determine the overall impression. Too high anti-squat values lead to a noticeable stiffening of the suspension and reduce grip and comfort. To always achieve the optimum anti-squat, we adjust the position of the pivot points for each frame size. The blue graphs show the anti- squat values for the four frame sizes depending on the rear cog (x-axis). For comparison, the gray 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 To be able to use the short suspension travel of the CELOS while braking, the rear triangle must not stiffen due to braking. This behavior is described by the anti-rise value. Somewhere below 100 % - a slight softening of the suspension - is optimal to maintain grip. The size-specific optimization of the swingarm pivot point, which is decisive for the anti-squat, results in the practically congruent, blue-shaded curve for all frame sizes.

Features

Superlight Layup

Introduced in 2026, the SUPERLIGHT layup is the result of years of optimization and experience in material selection and manufacturing. Our lightest layup – from 1.95 kg – with storage compartment and tool mount is approved for the most demanding ASTM Category 5, which also includes downhill use. Since the components typically don't allow for this, you shouldn't use the CELOS for downhill riding. But you can, for example, convert it into a TARVO and use it for enduro racing. The improvements are based on a new material mix with higher-performance fibers, a more elaborate lamination process and technological advances in manufacturing.
CELOS - Layup Options
Laminating of the carbon parts

Laminating of the carbon parts

In addition to the quality of fiber and matrix, manufacturing quality is decisive for the lightweight construction potential. Only if the prepreg layers are optimally compacted can a load-bearing structure be created. This requires craftsmanship and care as much as the manufacturing process itself. In the autoclave process, the material is strongly compacted by high pressure. At the same time, a vacuum is drawn in the laminate to prevent air inclusions. Careful process control using measurement data allows the quality of each individual frame to be verified. Monocoque construction requires elaborate mold design. All cable channels are laminated directly in the mold.

Lightweight Construction and testing at EFBE

Our frames make targeted use of the directional properties of carbon composite material. Strength, stiffness and weight are in the best possible balance. The elasticity of the material enables an elastic and maintenance-free joint – the Flexpivot – which saves additional weight. In addition to practical testing, we rely on extensive bench testing and work together with EFBE Prüftechnik GmbH in Waltrop, just north of Dortmund. For us, function and safety are just as fundamental as lightweight construction. The frame is suitable for use in Category 5 according to ASTM F2043-13. In order to use the entire bike in this category, suitable components must be specified.
CELOS - Lightweight construction and testing at EFBE
CELOS - Custom painting

Custom Painting

Weighing approx. 100 grams, Velociao's paint jobs are very light and leave plenty of room to customize the frame. After the surface has been lightly sanded, the filler is applied. This is followed by the paint layer, the decals and finally several layers of clear coat. Single-color paint jobs can be specified according to RAL and other color systems; car paint color codes are also possible. More complex and multicolored paint jobs can be realized after consultation.

Spare Parts Availability and Carbon Repair

Wear parts such as downtube and chainstay protectors, bolts and bearings are available at short notice. All bearings have standard outer dimensions, so in an emergency you can quickly find a replacement locally. The bearings we distribute are always full complement type and some are made of stainless steel. These bearings by Enduro Bearings feature improved seals and are filled with special grease. We keep spare parts in stock long term, so nothing stands in the way of riding your frame for many years. If repairs to frame parts are necessary, they can be carried out in our own carbon workshop. We offer this repair service exclusively for our own frames, as we know their construction and can therefore carry out repairs reliably.

LAST BIKES - Crash replacement

Crash Replacement

With our crash replacement program, we want to help you with damage that is not covered by our 6-year product warranty. Crashes are part of our sport. Even a small mistake can set off a chain of unfortunate circumstances that ends with you crashing into a tree, for example, and your frame being irreparably damaged. In such cases, we give you a discount on a new product or the necessary frame parts. Since we can stock or re-produce the individual parts of the frame, it is usually not necessary to replace the entire frame. The crash replacement program is valid for the first 3 years after purchase. You can find all the details on our crash replacement page.

RESPONSIBILITY AND ENVIRONMENTAL PROTECTION

When selecting our partners and suppliers, we attach great importance to good conditions, both for the environment and for employees. Therefore, we prefer suppliers from free democratic countries. In concrete terms, this means: the carbon fibers come from Japan, and the processing into prepreg takes place in Italy. The frames are laminated in Germany, the milled parts also come from Germany, and the storage compartment bags are sewn in Portugal. Colored frames are painted by Velociao in Berlin. Finally, all frames are assembled and tested by us in Dortmund and, if desired, built up into complete bikes. We work with 100 % green electricity (Naturstrom). We reuse packaging and protective materials as well as cardboard boxes wherever possible.
