We tested one of the most popular mountain biking platforms at the moment - a 140mm 27.5” trail bike - in the form of the Cube Stereo 140 HPA Pro. This is Cube’s entry level bike in this Stereo range: sporting an aluminium frame, and a mixture of XT, SLX and RaceFace components, along with the Fox Rhythm and Fox Float DPS shock, and Cube’s own proprietary dropper.
