CUBE REACTION PRO is a versatile and performance-focused hardtail mountain bike designed for trail riding, fitness, fast off-road adventures and everyday use. Its lightweight Aluminium Lite frame combines modern trail-ready geometry with a high-quality Shimano XT drivetrain and an adjustable RockShox air suspension fork.

The RockShox Recon Silver RL Air fork provides 100 mm of travel, helping maintain comfort and control over roots, rocks and uneven terrain. Air-spring adjustment allows the fork to be tuned to the rider, while the PopLoc remote lockout lets you lock the suspension directly from the handlebar for more efficient riding on smooth surfaces and climbs.

The Shimano XT 1x12 drivetrain combines an XT rear derailleur and shifter with a wide-range 10–51T Shimano Deore cassette. This provides a broad gear range for steep climbs and faster trail sections while keeping the drivetrain simple with a single 32T chainring.

Shimano BR-MT410 hydraulic disc brakes provide reliable stopping performance, with a larger 180 mm front rotor for additional braking power. The bike rolls on ACID EX25 Tubeless Ready wheels with Boost thru-axles and Schwalbe Racing Ray / Racing Ralph 2.25" tyres.

The Reaction frame also offers practical upgrade options. Internal cable routing keeps the appearance clean, the 30.9 mm seat tube is prepared for a remote dropper post, and mounting points are provided for compatible CUBE SIC carriers, ACID mudguards, a kickstand and accessories beneath the top tube.
