Description

CUBE Reaction TM ONE – Trail Hardtail Perfected

Welcome to the Trail Motion family. The CUBE Reaction TM ONE represents a new breed of hardtail mountain bike – one that doesn’t just dabble in trail riding but fully commits to it. With geometry borrowed from enduro bikes, proper trail components, and thoughtful details throughout, this is a hardtail that rides like it means business.

Trail Motion Geometry – Built for Aggressive Riding

The TM (Trail Motion) designation isn’t just marketing – it’s a geometry philosophy that changes how a hardtail performs on demanding terrain:

Long, Low & Slack:
  • 65° head tube angle – Confidence-inspiring stability on steep descents
  • 73.5° seat tube angle – Efficient climbing position despite the slack front end
  • Low standover height – Easy to move around on technical terrain
  • Short 408-427mm chainstays – Snappy handling and superior rear-wheel traction
  • Reach-focused sizing – Modern proportions for better weight distribution

This geometry makes the Reaction TM ONE feel planted and predictable when the trail gets rough, yet still agile enough to thread through tight singletrack.

CUBE Aluminium Lite Frame – Tough & Trail-Ready

The foundation is CUBE’s Aluminium Lite frame, constructed from heat-treated 6061 aluminium with AMF (Advanced Mechanical Forming) and Double Butting for optimal strength-to-weight ratio.

Trail-Specific Frame Features:
  • ISCG05 chain guide mount – Secure your chain on rough descents
  • Boost 148x12mm rear axle – Increased stiffness and wheel strength
  • UDH™ (Universal Derailleur Hanger) – Future-proof compatibility with next-gen drivetrains
  • 2.6″ tyre clearance – Run proper trail rubber for maximum grip and cushioning
  • Moulded chainstay protector – Quiet running and frame protection
  • Internal cable routing – Clean aesthetics and protected cables
  • Dropper post routing – Factory-installed internal routing for the included dropper
  • Tapered head tube – Precision steering and front-end stiffness
  • Smooth welded construction – Beautiful finish and enhanced durability

SR Suntour XCR34 Air Fork – 140mm of Trail Control

The SR Suntour XCR34 2CR Air fork with 140mm travel is a significant upgrade from typical XC forks:

  • 140mm travel – More cushioning for bigger hits and rough terrain
  • Air spring – Easy adjustment to suit your weight and riding style
  • 2CR damper – Compression and rebound control for tuned performance
  • Tapered steerer – Precise steering and robust construction
  • 15x110mm Boost axle – Stiff, confident front end
  • 34mm stanchions – Adequate stiffness for aggressive trail riding

This is the sweet spot for trail hardtails – enough travel to smooth out the rough stuff without feeling wallowy or disconnected.

Dropper Post Included – Game-Changing Control

Here’s where the TM ONE earns serious trail cred: it comes with a CUBE Dropper Post already installed:

  • Factory-fitted dropper post – Ready to ride from day one
  • Internal cable routing – Clean installation with handlebar-mounted lever
  • 30.9mm diameter – Strong and reliable
  • Variable travel by size – 120mm (XS), 150mm (S), 170mm (M/L/XL)
  • Instant seat height adjustment – Drop the saddle for descents, raise for climbs

A dropper post transforms how you ride trails. No more stopping to adjust your seat – just drop it before the descent and raise it for the climb. This alone adds massive value to the package.

Shimano Cues 1×11 Drivetrain – Simple & Capable

Shimano Cues represents the latest in affordable, reliable mountain bike drivetrains:

  • Shimano Cues RD-U6000-GS rear derailleur – Smooth, accurate shifting
  • Shimano Cues SL-U6000 Rapidfire Plus shifters – Positive, tactile gear changes
  • Shimano Cues FC-U6000-1 crankset – Single 32T chainring for simplicity
  • Shimano Cues CS-LG400 cassette – Massive 11-50T range (454% gear range)
  • KMC xGlide chain – Durable 11-speed chain

This 1×11 setup eliminates the front derailleur for simplicity, weight savings, and improved mud clearance, while the huge cassette range means you’ll never run out of gears.

Magura MT Thirty Brakes – Powerful German Engineering

Magura MT Thirty hydraulic disc brakes deliver serious stopping power:

  • 203mm front rotor – Maximum heat management and power on long descents
  • 180mm rear rotor – Balanced braking with excellent modulation
  • Hydraulic actuation – Superior power and feel
  • German engineering – Magura’s reputation for reliability
  • Tool-free reach adjust – Easy customization to hand size

The oversized 203mm front rotor isn’t overkill – it’s essential for confident braking on steep, technical descents where control matters most.

Schwalbe Trail Tyres – Magic Mary & Big Betty

The tyre combination is perfect for trail riding:

Front: Schwalbe Magic Mary 2.4″
  • Legendary cornering grip
  • Excellent braking traction
  • Performance compound balances grip and durability
  • Confident lean-angle performance
Rear: Schwalbe Big Betty 2.4″
  • Excellent climbing traction
  • Strong braking grip
  • Slightly faster rolling than Magic Mary
  • Durability for extended trail abuse

Both tyres run on ACID SLX 30 tubeless-ready rims, so you can convert to tubeless for lower weight, better traction, and fewer punctures.
