Conquer Any Trail with the Reaction TM: Designed for Ultimate Control and Confidence

For riders who crave adventure, the Cube Reaction TM Mountain Bike is your ticket to tackling tough trails with confidence. Engineered with a 65° head angle, 73.5° seat tube angle, and a low standover height, this bike is built for stability and reassurance when the trail throws its toughest challenges at you. Its short chainstays enhance handling and traction, while generous clearance supports tyres up to 2.5 inches for maximum grip. Features like stealth dropper post routing, a UDH hanger for future-proof gearing, a durable moulded chainstay protector, and an ISCG chain guide keep everything dialed in, making your ride smooth and worry-free.

Whether you're navigating technical descents or cruising flowy singletrack, the Reaction TM is built to deliver precision and performance. With a 140mm travel fork, a dropper post, and robust frame geometry, this hardtail is ready for anything.

CUBE Aluminium Lite: Lightweight, Strong, and Reliable

Crafted from heat-treated 6061 aluminium, CUBE Aluminium Lite delivers exceptional stiffness, fatigue resistance, and natural corrosion protection. This lightweight material ensures a nimble and responsive ride without unnecessary bulk, offering the perfect balance of strength and agility for your trail adventures.

SizeSplit: Perfect Fit for Every Rider

No matter your height, SizeSplit ensures your Reaction TM fits like a glove. Smaller sizes come with agile 27.5-inch wheels, while taller riders benefit from fast-rolling 29-inch wheels. This tailored approach guarantees a confident and comfortable ride for every rider.

Internal Cable Routing: Sleek, Clean, and Low-Maintenance

Cube's Internal Cable Routing keeps your bike looking sharp while reducing maintenance. By protecting cables from dirt, water, and abrasion, your gears and brakes perform flawlessly, ride after ride.

Trail Motion Geometry: Engineered for Adventure

Optimised for thrilling trail rides, Trail Motion Geometry delivers a confident, maneuverable ride. With extended front suspension, a rider-friendly cockpit, and precision-selected components like brakes and wheels, this design is tailored for fun and performance.

Dropper Post Ready: Elevate Your Control

Experience unparalleled confidence on descents with a dropper post. Cube's Dropper Post Ready frames are prepped with internal cable routing, making this upgrade seamless and functional for tackling steep terrain.

Smooth Welding: Strength Meets Style

Smooth Welding not only gives the Reaction TM its sleek, seamless look but also enhances frame durability by minimising stress points in welded areas. It’s a marriage of aesthetics and functionality.
