It's time to reassess how good you think a trail hardtail can be. The Acid's SRAM NX Eagle 1x12 transmission is built to deliver quick, precise shifts time after time, over a gear range big enough to make light work of any climb you care to take on. A RockShox Silver air fork serves up 100mm of plush, easily adjustable, trail-taming travel. And powerful Shimano hydraulic disc brakes, with a bigger rotor up front, help keep your speed in check on the descents. Which trail will you tame next?

  • Aluminium Lite AMF ARG frame with internal cable routing
  • Rockshox Judy Silver TK air suspension fork with 100m travel and remote lockout
  • SRAM Eagle 12-speed drivetrain
  • Shimano MT400 hydraulic disc brakes
  • NB: XS and S sizes use 27.5" wheels, M, L, XL and XXL sizes use 29" wheels

They say that the frame is the heart of a bicycle. It's the reason Cube put so much care into the Acid's design, using their Advanced Mechanical Forming process and 6061 aluminium to build a frame that's stiff where it needs to be, but still comfortable and responsive. Complex profile main tubes and a tapered head tube ensure efficient pedalling and accurate steering, and the Agile Ride Geometry puts you firmly in control for a fun, safe ride every time. There are rack and guard mounts for added versatility, and internal cable routing reduces maintenance. It's all in the detail...
