Challenging trails need a suspension set-up to match, which is why we gave the Stereo Hybrid ONE77 HPC SLX a Fox Float 38 Rhythm fork and Float X Performance shock. Together, they deliver 170mm of rock-swallowing travel front and rear, with loads of adjustment so you can get it dialled. The Bosch CX drive and 800Wh PowerTube battery give your pedalling an unobtrusive but very effective boost, via Shimano's legendary XT 1x12 gears – and the top tube-mounted Kiox 400C display shows you exactly what's going on. Meanwhile, the mullet Newmen Performance 30 wheelset – shod with Continental Argotal and Kryptotal 2.4in tyres – is held in check by Shimano's new XT hydraulic disc brakes. Add it all up and, with a remote dropper seatpost, too, it's the perfect formula for big mountain fun.

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.Custom Build Inspiration
