Big days out in the mountains place big demands on both bike and rider. Luckily the Stereo 140 HPC SL 27.5 is up for the challenge. This carbon and aluminium all mountain machine's svelte looks aren't its only attraction. Years of experience building full-suspension bikes have gone into details like the hidden rocker pivots, neat internal cable routing, superbly efficient kinematics and confidence-inspiring Agile Trail Geometry. Making the most of the resulting sharp handling and efficient power transfer meant, of course, speccing some top-grade components. Read more... We began with a RockShox Pike Select+ fork and paired it with a RockShox Deluxe Select+ shock at the rear, for total control over bump absorption at any speed. Newmen's light, strong Evolution wheelset provides a solid base for anchoring a pair of Schwalbe's big-volume, grippy tyres and Shimano's 1x12 XT transmission and hydraulic disc brakes take care of stop-and-go duties. Add it all up, and it makes for a light, agile, fast and supremely capable companion on even the toughest of trails. Go explore - but make sure you take the Stereo 140 HPC SL with you for the ride.
