The Cube Reaction TM One is built to tackle the kind of trails that make you grin from ear to ear. Designed under Cube’s Trail Motion philosophy, it takes the proven versatility of their Reaction hardtail and injects it with more aggressive geometry, burlier components, and serious trail intent.

The Aluminium Lite frame uses Cube’s Advanced Mechanical Forming (AMF) technology for strength, precision, and reduced weight. Its Trail Motion Geometry features a 65° head angle and 73.5° seat tube angle, giving you a stable, confident ride when the descents get steep and the surface gets rough. Short chainstays keep the handling sharp, while the low standover height boosts confidence on technical terrain. There’s even clearance for tyres up to 2.5” wide and integrated stealth dropper routing for clean looks and function.

Up front, the SR Suntour XCR34 2CR Air fork delivers 140mm of plush, adjustable suspension, perfectly suited for rough trail surfaces and fast, flowing descents. Its tapered steerer and 15x110mm Boost axle ensure stiffness and precise steering when pushing hard through corners.

The Shimano Cues 11-speed drivetrain provides smooth, reliable shifting with a wide 11–50T cassette, giving you all the range you need to climb steep hills and power through descents. Complementing that, the Magura MT Thirty 4-piston hydraulic disc brakes — with a large 203mm rotor up front — deliver powerful, consistent braking control in all conditions.

Rolling on ACID SLX 30 tubeless-ready wheels and Schwalbe Magic Mary (front) and Big Betty (rear) 2.4” tyres, the Reaction TM One offers superb traction and control over roots, rocks, and loose ground. It’s a setup that inspires confidence whether you’re attacking descents or tackling technical climbs.

A CUBE dropper post comes as standard, letting you adjust your saddle height on the fly for steep descents or seated climbs. Practical features like an ISCG-05 chain guide, UDH hanger, and durable moulded chainstay protector add reliability and future-proofing to the package.

From big trail days to bike park sessions, the Cube Reaction TM One is a hardtail that thrives where others hesitate — combining strength, control, and trail-ready geometry in one capable, confidence-inspiring ride.
