Fast, light, tough
The 2027 Cube Reaction range blends the low weight and efficiency of an XC race bike with the everyday versatility of a trail hardtail. The carbon frames are tuned for stiffness, comfort and precise handling. Every model is dropper‑post ready and includes practical mounting points for accessories. It is a true all‑rounder for riders who want pace, control and reliability on mixed terrain.
XC pedigree
The Reaction C:62 and C:68X frames take their cues from Cube’s experience on the race circuit. Agile Ride Geometry gives quick handling and confident stability. Advanced Twin Mold construction keeps weight low and strength high. Whether you are racing or exploring local trails, the Reaction platform rewards riders who like to push the pace.
