Cube Reaction

Is the Cube Reaction a good mountain bike for beginners?

The Cube Reaction is well-suited for beginners, provided the intended use and model variant are a good match. The classic HPA models offer a balanced riding position, predictable steering, and a robust construction. This makes them suitable for initial mountain bike tours, gravel paths, and simple trails. Beginners do not need to get used to the additional rear suspension of a full-suspension bike and can learn basic riding techniques directly.

An aluminum model is usually the more sensible choice when looking for your first sporty mountain bike. The HPA frame keeps the purchase price lower compared to carbon. This allows the available budget to be invested in components that are noticeably effective while riding. These include a responsive suspension fork, hydraulic disc brakes, reliable shifting, and grippy tires.

If you primarily ride on forest trails, gravel paths, and simple woodland tracks, a classic Cube Reaction HPA is usually a better fit than a TM model. The sporty, though not heavily descent-oriented geometry makes longer climbs easier and keeps the bike efficient on flat terrain. A suspension fork with moderate travel is sufficient for small roots, potholes, and curbs.

If you already know that you want to frequently ride on steep or technically demanding trails, you should consider the TM version. It offers more suspension travel, wider tires, and a geometry with greater reserves for descents. However, these features increase the weight and make the bike somewhat less agile on long, flat tours.

For your purchasing decision, a clear classification based on usage helps:

• For everyday rides, forest paths, and getting started with mountain biking, a Cube Reaction HPA is an uncomplicated choice.
• For fast cross-country laps and long climbs, a Cube Reaction C:62 is worth it if low weight is important and a higher budget is available.
• For technical trails, steeper descents, and jumps within the intended scope of use, a Cube Reaction TM is a better fit.
• For longer tours with electric assistance, the Cube Reaction Hybrid is the appropriate model family.

Regardless of the equipment, the frame size must be correct. A bike that is too large feels difficult to control in tight corners, while a frame that is too small can become uncomfortable on longer distances. Body height and inseam provide an initial orientation. For the final choice, top tube length, reach to the handlebars, and personal seating position are also relevant.

With the HPA frame, Cube shapes the aluminum tubes so that material is used only where it is needed for stability and stiffness. Smooth-welded seams ensure clean transitions between the tubes. Aluminum is an attractive option for budget-conscious riders because it enables a durable construction at a lower price point.

The C:62 frame is crafted from carbon fibers and resin. The Twin Mold process allows for control over fiber orientation and frame shape during production. This enables targeted reinforcement of high-stress areas without increasing the overall bulk of the frame. The result is reduced weight with high rigidity.

What does the additional suffix TM mean for the Cube Reaction?

At Cube, TM stands for Trail Motion. A Cube Reaction TM is not a classic cross-country hardtail focused on minimal weight. It is geared more towards technical trails and controlled descents. The frame geometry and components therefore offer more reserves when the terrain becomes steep, loose, or heavily rooted.

• The Cube Reaction TM comes standard with a suspension fork featuring 130 millimeters of travel. This can absorb larger impacts and keeps the front wheel more controllable on uneven terrain.
• A slack head angle of about 65 degrees extends the wheelbase and ensures greater stability on steep descents.
• A dropper seatpost, wide tires, and powerful brakes make it easier to maintain control in technical sections.

The dropper seat post can be lowered while riding using a handlebar lever. This allows the rider to shift their center of gravity backwards and downwards on descents. On a classic hardtail with a fixed, high seat position, this movement is significantly restricted. Before the climb, the seat post extends again, allowing for an efficient pedaling position.

Wide tires of up to about 2.5 inches increase the air volume and enlarge the contact patch. This improves grip on loose ground and dampens minor impacts on the unsprung rear wheel. The exact tire width depends on the model, the model year, and the available frame clearance.

Depending on the equipment, powerful disc brakes are used for the braking system. Four-piston calipers offer more reserves on long and steep descents than simple two-piston systems. The diameter of the brake discs, the pads used, and the correct adjustment are also crucial.

The Cube Reaction TM is suitable for challenging trails, but remains a hardtail. The rear wheel has no suspension and can lose ground contact more easily on fast, rough sections. Riders must compensate for bumps more actively with their arms and legs. Those who frequently ride on very steep terrain, perform large jumps, or visit bike parks should consider whether a full-suspension bike might be better suited for their needs.

On flat routes, the trail-oriented equipment also comes with disadvantages. Wide tires roll harder, the long suspension fork raises the front end, and the more robust components increase the weight. For predominantly relaxed tours, a classic Reaction is therefore more efficient. The TM is worthwhile when the proportion of technical descents is the deciding factor.

Retrofitting a luggage rack to a Cube Reaction

Many Cube Reaction HPA frames feature mounting points for mudguards and luggage racks. This allows the hardtail to be equipped for commuting, longer tours, or short shopping trips. Cube and their accessory brand ACID offer components that are tailored to specific frames and mounting systems. Before purchasing, check that the frame, luggage rack, and wheel size are compatible with one another.

There is no factory-equipped "FE" version of the non-motorized Cube Reaction. Everyday accessories must always be retrofitted to the HPA frame independently.

On the Cube Reaction C:62, the installation of a classic luggage rack is often restricted or not intended. Carbon frames may only be loaded at the approved points. Clamps or improvised mounts can damage the frame. If the necessary mounting eyelets are missing, no luggage rack should be installed without express approval.

Load limits also apply to the HPA model. The permissible system weight includes the bicycle, rider, clothing, and luggage. A mounted luggage rack does not increase this limit. Those wishing to use panniers for longer tours should therefore observe the weight limits of both the bicycle and the rack.

For sporty day trips, a saddlebag or frame bag may suffice. These do not require a fixed luggage rack and have less impact on handling. However, when using a dropper seat post, the bag must maintain sufficient clearance from the rear tire and the moving part of the post.
