Big days out in the mountains place big demands on bike and rider. Luckily the Stereo 140 SL 27.5 is up for the challenge. Completely redesigned for 2018, this carbon and aluminium all mountain machine's svelte looks aren't its only attraction. Making the most of the frame's sharp handling and efficient power transfer meant speccing some top-grade components. So we began with Fox's 34 Performance fork, and added a matching Float DPS EVOL shock at the rear. Fulcrum's light and strong Red55 EM wheelset boasts a 27mm internal rim width for anchoring big volume tyres, and Shimano's peerless XT 2x11 transmission and brakes take care of stop and go duties. Light, agile, fast and supremely capable on even the toughest of trails, it's almost certainly the mountain companion you've been looking for.
