CUBE Stereo C:62

The C:62 carbon frame combines low weight with high stiffness in areas subject to high loads. For the Stereo C:62 SLT, the top model in the series, the manufacturer claims a total weight of around 13.6 kilograms – a remarkably low figure for a 150 mm trail bike.

The Stereo HPC variants combine a C:62 carbon main frame with an aluminum rear triangle. The travel, basic geometry, and adjustable headset remain the same. The entry-level Stereo HPC Race model brings the new 150/145 mm platform to market starting at around 1,999 euros.

The angle-adjustable headset allows the head tube angle to be adjusted between approximately 64.2 and 64.8 degrees. This moves the new Stereo geometrically closer to a thoroughbred trail bike than the previous One44 generation, which ranged between 65.4 and 66 degrees depending on the headset position. In frame size L, the reach increases from the previous 473/474 mm to 478/480 mm, and the chainstays grow from 434 to 439 mm.

The storage compartment in the down tube remains an integral part of the platform and is larger on the 2027 model. A spare tube, CO₂ cartridge, or tools can be stowed directly in the frame. In addition, there is more room for long dropper seat posts – up to 200 mm of travel is possible in frame sizes L and XL.

Cable routing on the new Stereo can be chosen flexibly, which can make maintenance easier compared to fully internally routed cables.

UDH (Universal Derailleur Hanger) and ISCG05 mounts remain standard features. A damaged derailleur hanger is thus easier to replace, and the ISCG mount allows for the installation of a chain guide if needed.

A modular computer mount is now anchored into the frame design, creating a uniform, tidy cockpit look.

Wheel size on the new Stereo is 29 inches throughout – with the exception of the small frame sizes, where 27.5 inches continues to be used.

The top model, the Stereo C:62 SLT, features a Fox 36 Factory fork with GRIP-X2 cartridge and 150 mm of travel at the front, and a Fox Float X Factory shock at the rear. Shifting is handled electronically by the Shimano XTR Di2 M9250, complemented by a Race Face ERA crankset, XTR brakes, and a Fox Transfer Factory dropper post. This configuration is priced at 5,499 euros.

The fundamental material technology has not changed compared to previous models: C:62 stands for a 62 percent carbon fiber content in the composite material. The remaining portion consists of the resin system, which binds the fibers, holds them in shape, and transfers forces between the layers. A controlled ratio of fibers and resin is an important part of lightweight construction—too much resin increases weight without increasing the desired properties of the fibers to the same extent.

For C:62, Cube uses an increased proportion of high-modulus fibers with high stiffness, especially in areas that should deform as little as possible under load: the bottom bracket, the transition to the down tube, the head tube, and the pivot points of the rear triangle.

In the Advanced Twin Mold process, the carbon is layered in an outer mold while a rigid inner core supports the layers during curing. This is intended to prevent fibers from shifting or wrinkling, and allows for a more targeted distribution of material in highly stressed areas.

The resin system contains finely dispersed nanoparticles intended to increase the composite material's resistance to external forces. This does not change the fact that a carbon frame must be carefully inspected after a hard crash. Deep scratches, visible cracks, soft spots, or unusual noises require attention in a specialist workshop.

The high stiffness of a carbon frame does not mean that the entire bike rides harshly or uncomfortably. Tire width, air pressure, wheels, suspension, and frame kinematics have a much greater influence on comfort. On the Stereo 2027, the suspension—now featuring a horizontally mounted shock and new linkage—handles the majority of shock absorption, while the frame is designed to guide the pivot points precisely in relation to one another.

• Start with your usual travel distances, not the largest travel category available. The new Stereo already covers a wide range with 150/145 mm without sacrificing much uphill efficiency.
• Check if you lean more towards enduro. For regular bike park days or rough trails, it’s worth comparing with the Fritzz instead of pushing a Stereo to its absolute limits.
• Choose between C:62 and HPC depending on how much you notice the extra weight of the aluminum rear triangle variant in everyday use and how much the weight savings are worth to you.
• Use the adjustable headset. The slacker position offers more stability on steep descents, the steeper position more direct handling on winding trails. Test both settings on familiar routes.
• Consider the increased reach and chainstay values. Compared to the previous models, the new platform in size L has become slightly longer – a test ride or a consultation on the right frame size is worthwhile.
• Compare the components according to your intended use. For long descents, powerful brakes, sturdy tires, and a well-tuned suspension are often more important than the final weight advantage between C:62 and HPC.

The new Cube Stereo makes the most sense if you are looking for a versatile trail bike that masters long climbs as confidently as demanding descents – without being as uncompromisingly downhill-oriented as the Fritzz. Anyone who spends most of their time in the bike park or consistently seeks out rough terrain is better served by the Fritzz and its 170 mm of travel.
