The Stereo Hybrid ONE77 HPC AT is built with big mountains in mind. To that end, we fitted Fox's Float 38 Factory fork and Float X2 Factory shock – because when you're making full use of 170mm of travel, you need to know you're in good hands. Shimano's XT Di2 1x12 gears select with uncanny electronic precision, getting your power to the trail with help from Bosch's CX drive, the 800Wh PowerTube battery, a Kiox 400C top tube-mounted display and an ACID carbon crank. We added a remote dropper seatpost for extra confidence and manoeuvrability on tough trails, while Shimano XT hydraulic disc brakes with ABS Pro ensure you can safely keep your speed in check. And Newmen Beskar 30 wheels – in mullet configuration – with Schwalbe 2.5in Magic Mary and Albert tyres – keep you rolling, whatever obstacles lie in your path.

Frame description
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.
