The Stereo Hybrid ONE77 HPC frame – with 170mm travel front and rear and a mullet wheel setup with 29in front and 27.5in rear – is all you need for big days out on big mountain trails. But, as with all CUBE designs, the devil is in the detail. So, for example, we added Integrated Cable Routing for super-clean looks, and then threw in an angle-adjustable headset so that you can tweak the handling to your taste. The 800Wh PowerTube battery sits unobtrusively in the carbon down tube, just above the Bosch CX drive. A UDH dropout on the aluminium rear triangle is tough and future-proof, and we also added a Direct Mount chain guide to keep you driving forwards even when the going gets rough.
The Stereo Hybrid ONE77 HPC AT's distinctive Actionteam livery gives a hint of this bike's serious intent. With a mullet wheel set-up, CUBE carbon frame tech, Bosch drive with 800Wh battery and Shimano XT ABS Pro hydraulic disc brakes, it's all set for big days out in big mountains..

Key Highlights
ABS Pro Braking: The most significant safety advancement for 2026. It allows for maximum braking force on the front wheel while preventing tucking or sliding, especially on wet roots and loose gravel.
Factory-Level Suspension: The "Full Kashima" setup isn't just for show; the gold coating reduces friction (stiction), providing unmatched small-bump sensitivity.
Shimano XT Di2: Features "Free Shift" technology, allowing the motor to rotate the chainring slightly so you can change gears while coasting—perfect for pre-selecting a gear before a sudden climb after a descent.
Mullet Agility: By using a smaller 27.5" rear wheel, Cube gives the bike a shorter effective chainstay, making it significantly easier to whip through tight corners than a full 29er.
