Description

CUBE Reaction Pro – Where Trail Performance Meets Value

The CUBE Reaction Pro represents the ideal balance of function, reliability, and performance in a modern hardtail mountain bike. Designed with trail-ready geometry and equipped with dependable components from industry leaders Shimano and RockShox, this bike empowers you to react confidently to whatever the trail throws your way.

Intelligent Frame Design – Aluminium Lite Technology

At the heart of the Reaction Pro is CUBE’s Aluminium Lite frame, crafted from heat-treated 6061 aluminium that’s stiff, fatigue-resistant, and naturally corrosion-resistant. Advanced manufacturing techniques including Double Butting reduce weight without compromising strength, while Smooth Welding creates seamless tube junctions that look stunning and minimise load peaks for enhanced durability.

Key Frame Features:

  • Tapered Head Tube – Increases front-end stiffness for more confident, precise handling
  • Internal Cable Routing – Protects cables from contamination and damage while cleaning up aesthetics
  • Threaded Bottom Bracket – Easier maintenance and more durable than press-fit alternatives
  • Flat Mount Disc Brake – Integrated, low-profile brake mounting for cleaner lines
  • SIC Mount – Semi-Integrated Carrier mounting for easy rack installation
  • FM Kickstand Mount – Secure, unobtrusive mounting for practical everyday use
  • Mudguard & Carrier Mounts – Integrated ACID mounting points for versatile use
  • Size Split – The Right Wheel for Your Frame Size

CUBE’s innovative Size Split philosophy ensures optimal fit and handling across the size range:

27.5″ wheels (XS, S frames) – More agile handling and better proportions for shorter riders
29″ wheels (M, L, XL, XXL frames) – Fast-rolling efficiency and obstacle-conquering capability for taller riders
This intelligent approach means every rider gets a bike that feels custom-built, with geometry that suits their stature perfectly.

Trail-Ready Geometry

The Reaction Pro’s geometry strikes the perfect balance between climbing efficiency and descending confidence:

  • Lower top tube – Easier standover and more room to move
  • 68.5° head tube angle – Stable and confidence-inspiring on descents
  • 73.5° seat tube angle – Efficient pedaling position for climbing
  • Clearance for 2.25″ tyres – Room for wide, grippy rubber for maximum traction
  • Dropper post compatible – Upgrade path as your skills progress
  • Shimano XT 1×12 Drivetrain – Precision Shifting

The legendary Shimano XT groupset is renowned worldwide for accuracy, durability, and performance:

  • Shimano XT RD-M8100-SGS rear derailleur – ShadowPlus technology for quiet, reliable shifting
  • Shimano XT SL-M8100 shifters – Crisp, precise gear changes
  • Shimano Deore CS-M6100 cassette – Enormous 10-51T range for steep climbs and fast descents
  • Shimano FC-MT511 crankset – 32T chainring with Boost spacing for optimal chainline
  • KMC X12 chain – Smooth, durable 12-speed performance

This 1×12 setup eliminates the front derailleur for simplicity and weight savings while providing all the gears you need for any terrain.

RockShox Judy Silver Air Fork – Smooth & Adjustable

The RockShox Judy Silver TK Air fork with 100mm travel brings sophistication to your ride:

  • Air spring – Easy adjustment to suit your weight and riding style
  • PopLoc remote lockout – Control fork compression from the handlebar for efficient climbing
  • 100mm travel – Perfect for cross-country and trail riding
  • Proven reliability – RockShox engineering you can trust

Shimano Hydraulic Disc Brakes – Confidence-Inspiring Control

Shimano BR-MT410 hydraulic disc brakes deliver consistent, powerful stopping in all conditions:

  • 180mm front / 160mm rear rotors – Optimal heat management and modulation
  • Hydraulic actuation – Superior feel and less hand fatigue than cable brakes
  • All-weather performance – Reliable braking in wet, muddy, or dusty conditions
  • Low maintenance – Self-adjusting pads and sealed system
