• Quieter while coasting and pedaling
• New Hill Hold system and Extended Boost for technical climbs

You can tell from its purposeful stance and mullet wheel sizing that the Stereo Hybrid ONE77 HPC Race 800 means business. But the devil, as always, is in the detail. The Bosch CX drive and 800 Wh PowerTube battery work with Shimano's reliable Deore 12-speed gears to swallow tricky routes whole. Meanwhile, a pair of Magura MT Thirty hydraulic disc brakes and 2.4in Schwalbe Magic Mary and Big Betty tyres have the grip you need to stay in control, whatever the trail throws your way. A Suntour Aion 38X fork and Edge Evo 2 CR shock help keep the rubber side down and rolling. And, with a remote dropper post thrown into the mix, the only question is which line you'll take back down the mountain.

Frame description
The Stereo Hybrid ONE77 HPC frame – with 170mm travel front and rear and a mullet wheel setup with 29in front and 27.5in rear – is all you need for big days out on big mountain trails. But, as with all CUBE designs, the devil is in the detail. So, for example, we added Integrated Cable Routing for super-clean looks and reduced maintenance, and then threw in an angle-adjustable headset so that you can tweak the handling to your taste. The 800 Wh PowerTube battery sits unobtrusively in the carbon down tube, just above the Bosch CX drive. A UDH dropout on the aluminium rear triangle is tough and future-proof, and we also added a direct mount chainguard to keep you driving forwards even when the going gets rough.
