Challenging trails need a suspension set-up to match, which is why we gave the Stereo Hybrid ONE77 HPC SLX a Fox Float 38 Performance 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 a strong, controllable 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 powerful XT hydraulic disc brakes. Add it all up and, with a remote dropper seatpost, too, it's the perfect formula for big mountain fun.
