Product Information

Full details

The Cube Reaction TM Pro Mountain Bike is designed for riders seeking fun and stability on challenging trails. Its key benefit is a progressive frame geometry paired with robust components that offer confidence and control. A potential caveat is that its aggressive trail focus may be more than needed for casual cross-country riding. This hardtail mountain bike features a lightweight Aluminium Lite frame, 140mm suspension fork, and reliable Shimano hydraulic disc brakes, making it ready for demanding terrain.

FAQs

What is the purpose of Trail Motion Geometry?

Trail Motion Geometry is designed to provide a more stable and confidence-inspiring ride on descents and technical terrain. It typically involves a lower bottom bracket, slacker head tube angle, and longer reach, which helps keep the rider centered and in control.

Is this bike suitable for long-distance cross-country riding?

While the bike is efficient due to its hardtail design and lightweight frame, its aggressive trail geometry and 140mm fork are optimized for descending and technical terrain. For purely long-distance, less technical cross-country riding, a bike with less travel and a more XC-oriented geometry might be more suitable.

What size wheels does this bike come with?

The Cube Reaction TM Pro utilizes a size-split system. Smaller frame sizes (like XS, S) typically come with 27.5" wheels for better agility, while larger sizes (M, L, XL) come with 29" wheels for better rolling speed and momentum.

Can I convert this bike to tubeless tires?

Yes, the Newmen Performance 30 wheels and Continental Kryptotal tires are listed as Tubeless Ready (TLR). You will need tubeless rim tape, tubeless valves, sealant, and a tubeless-compatible tire or rim, along with a way to seat the tire bead.

What kind of riding is this bike best suited for?

This bike is best suited for aggressive trail riding, enduro riding (as a hardtail option), and general mountain biking on varied and challenging terrain. It excels on descents, through rocky sections, and on singletrack where stability and control are paramount.

What is the benefit of internal cable routing?

Internal cable routing keeps the cables and hoses protected from the elements, reducing the risk of damage and wear. It also contributes to a cleaner aesthetic and can make it easier to keep the bike clean.

How do I know if I need to bleed my brakes?

If your brake levers feel soft, spongy, or pull all the way to the handlebar without firm resistance, it generally indicates that air has entered the hydraulic system and the brakes need bleeding.

Troubleshooting

Brakes feel spongy or lack stopping power

The hydraulic brake system may need bleeding. Check for obvious leaks. Consult a bike mechanic for bleeding or if issues persist.

Gears are not shifting smoothly or are skipping

Check derailleur hanger alignment. Ensure the derailleur cable is properly tensioned and free of debris. A tune-up by a mechanic might be necessary.

Suspension fork is stiff or not responding well

Ensure the fork's air pressure is set correctly for your weight. Check for any stanchion damage or dirt. Refer to the Marzocchi manual for basic maintenance or contact a service center.

Dropper post installation query

The bike is 'dropper post ready' with internal routing. Consult the specific dropper post manufacturer's installation guide or a qualified bike mechanic for fitting and setup.

Excessive noise or creaking from the bike

Identify the source of the noise. Common areas include the bottom bracket, headset, seatpost clamp, or pedals. Ensure all bolts are tightened to the correct torque specifications.

Pros and Cons

Pros

  • Offers excellent stability and control on technical trails due to its geometry and suspension.
  • Lightweight and strong Aluminium Lite frame provides efficient pedaling and durability.
  • Reliable Shimano components ensure consistent performance and stopping power.
  • Dropper post readiness enhances maneuverability and confidence on descents.
  • Internal cable routing simplifies maintenance and provides a cleaner aesthetic.

Cons

  • May feel over-specced or less efficient for riders who primarily use their bike on smooth, cross-country trails.
  • As a hardtail, it lacks the rear suspension comfort of a full-suspension bike on very rough terrain.
  • The aggressive geometry might feel less nimble on tight, switchback climbs compared to a more XC-oriented bike.

Setup, Compatibility & Care

When you receive your Cube Reaction TM Pro, it will require some final assembly and adjustments by a qualified bicycle mechanic to ensure safety and optimal performance. This typically includes fitting the handlebars, pedals, and front wheel, and checking brake and gear adjustments. The bike is dropper post ready, meaning it has the internal routing for a dropper post cable, but the dropper post itself is usually an aftermarket purchase and installation. Ensure compatibility with standard 1 1/8" to 1.5" tapered steerer tubes for potential fork upgrades. The bike uses standard Boost 148mm rear hub spacing and a PressFit bottom bracket.

Care Instructions:

  • Cleaning: Regularly clean the bike with mild soap and water. Avoid high-pressure washers, especially around bearings and suspension seals. Dry thoroughly after washing.
  • Drivetrain: Keep the chain clean and lubricated. Use a degreaser for thorough cleaning periodically. Check for wear on the chain, cassette, and chainring.
  • Brakes: Inspect brake pads for wear. Ensure brake levers have a firm feel; if spongy, the brakes may need bleeding.
  • Tires: Maintain recommended tire pressure for optimal grip and to prevent pinch flats. Check tires regularly for cuts or excessive wear.
  • Suspension Fork: Refer to the Marzocchi Bomber Z2 manual for specific lower leg cleaning and lubrication recommendations. Avoid spraying water directly into the fork seals.
  • Storage: Store the bike in a dry place, away from direct sunlight and extreme temperatures.
