The CUBE Reaction Pro is designed to deliver a confident, efficient ride whether you’re exploring local trails or clocking up miles on mixed terrain. Its lightweight aluminium hardtail frame balances durability with agility, while the RockShox Judy Silver air fork provides 100mm of smooth, easily adjustable travel to take the edge off rough ground. With modern trail-ready geometry, a tapered head tube and clearance for wide tyres, the Reaction Pro feels composed and predictable when the pace picks up.
Shimano’s proven XT 1x12 drivetrain brings crisp, reliable shifting and a huge gear range, making steep climbs and fast transitions effortless. Matching Shimano hydraulic disc brakes deliver consistent stopping power in all weather conditions, while fast-rolling 2.25in Schwalbe tyres maintain grip and efficiency across hardpack and loose surfaces. Practical touches like internal cable routing, mounts for mudguards and a carrier, and dropper post compatibility make the Reaction Pro a versatile hardtail that’s ready to grow with your riding ambitions.
