BERG 155

Master of the mountain

Enduro geometry paired with a lightweight chassi makes BERG 155 ready to tackle every part of the mountain. The working name Mini-Superenduro picks the best from the all mountain and enduro category to end up with a poppy, fast and fun enduro.

light weight suspension chassi

With 155mm of progressive rear suspension and 160mm up front there is no chance for the suspension platform to feel sluggish or heavy. BERG 155 offers an optimal balance between agility and power, primed to tackle every mountain challenge. 29 inch wheels help you roll over and create unrivaled grip in all situations.

super enduro geometry

A stable 64° fork angle, paired with a “low, long, and slack” design philosophy, positions you perfectly to master everything from winding mountain trails to adrenaline-pumping descents. Our goal designing the bike was to never run out of geometry.

Front and rear carbon triangle are connected by a CNC-machined one piece aluminium rocker making the rear end stabile and robust. This makes for immediate and predicted response on your riding input.

    We help you to choose the correct size for you and your riding style. In general a smaller sizes will be a bike with shorter wheelbase that is more playful. In the opposite a larger size will have a longer wheelbase and be more stable.

    Words from our engineer

    “What started out as a blank canvas to discover the perfect blend of suspension performance and chassis feel has resulted in a bike that does everything that was asked for at the beginning.The heart of the chassis all stems from the 1 piece CNC Aluminium rocker that was designed with manufacturing accuracy in mind and this marries together perfectly with the high performance carbon front and rear triangles. 

    This is a bike that will excel not only on the Swedish trails, but across the globe as a bike that punches well above it’s weight.”

    Swedish Craftsmanship & Global Quality

    Both the front and rear triangles boast a sturdy carbon fiber structure, complemented with a one-piece CNC-machined 6082 aluminum link, delivering both durability and stiffness.

    Like a piece of jewelry, our rocker link doesn’t just improve the bike’s performance; it also brings a sleek, minimalistic design. And it’s all manufactured with care in Sweden.

    frame highligts

    • The chain stay protection follows the shape of the frame and protect against annoying chain slaps

    • Internal cable routing

    • UDH (Universal derailleur hanger)

    • Threaded bottom bracket for easy maintenance

    • ISCG05 for installment of bash guard

    • Oversize upper headset bearing creates the possibility of a fully integrated cockpit. 1,5″/1,5″

    • 5-year frame warranty

    • Weight 2900g in size M/L


    The matt colors of the frame are all found in the Nordic nature. The main colors of pine, bark and black granite are matched with accent color in a nearby spectrum for a discreet Scandinavian design.

    Progressivity without fuss

    By working directly with the engineers at the suspension manufacturers, we ensure the correct level of damping in all situations. The natural kinematics of the frame are matched and tailored with the perfect shock characteristics. Delicate at the beginning of the stroke, efficient and supportive in the middle and good bottom out control.

    leverage ratio

    We settled on a 30% progressive leverage curve that starts quite high and then falls evenly through the travel.  The progressive frame increases the ability to experiment with the air volume in the shock to achieve the desired feel. This is also a requirement to be able to run a coil shock. Since the spring compresses linearly, the shock needs a progressive frame for the bike’s rear suspension to be progressive.

    adapted for any climate

    The Nordic environment can be extremely testing, so our bikes are built to excel in these conditions. All components are tested with elements in mind and no detail is left to chance. Some examples are:

    • We use only 4-piston calipers  ensuring maximum bite in every condition or environment.

    • High-quality suspension for a buttery experience.

    • Tires containing several different rubber compounds for the right grip level in all wheel angles.

    choose BERG 155

    If you are looking for a full-suspension mtb that  doesn’t flinch when thrown in at the deep end, but instead begs to be challenged further.  

    Thanks to an all-carbon frame, modern geometry and only carefully selected, high-quality components. the BERG 155 is capable of tackling any terrain you can throw at it, while maintaining an composed and enjoyable riding experience time after time. 

    Buying directly from the manufacturer, you not only get more for your money, but also a greater freedom of choice as the bikes are hand-built in Sweden.

    We love suspension

    We delve deeper into shock absorption and how much you really need. We match this against our various models. A pro can ride fast and master different bikes in the same terrain, while a less experienced MTB cyclist can get a lot of support by choosing the right bike for the purpose.
