Challenging trails need a suspension setup to match, which is why we gave the Stereo Hybrid ONE77 HPC SLX 800 a Fox Float 38 Rhythm Grip 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 800 Wh PowerTube battery give your pedalling an unobtrusive but very effective boost, via Shimano's legendary XT 1x12 gears. Meanwhile, the mullet Newmen Performance 30 wheelset – shod with Schwalbe Magic Mary and Tacky Tan 2.4in tyres – is held in check by Shimano's powerful, progressive XT hydraulic disc brakes. Add it all up and, with a remote dropper seatpost too, it's the perfect formula for big mountain fun.
