The Stereo Hybrid ONE77 HPC AT 800 is built with big mountains in mind. To that end, we fitted Fox's Float 38 Factory GripX2 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. Sram's XO Eagle Transmission 1x12 gears select with uncanny electronic precision, getting your power to the trail with help from Bosch's smooth, quiet CX drive and the 800 Wh PowerTube battery. We added a remote dropper seatpost for extra confidence and manoeuvrability on tough trails, while Shimano XT hydraulic disc brakes ensure you can keep your speed in check. And Newmen Beskar 30 wheels – in mullet configuration – with Schwalbe 2.4in Magic Mary and Tacky Tan tyres – keep you rolling, whatever obstacles lie in your path.
