The Stereo Hybrid ONE77 HPC SLT leaves nothing on the table in its pursuit of big-mountain riding perfection. The mullet wheelset is built around a pair of Newmen Phase 30 carbon wheels, shod with Schwalbe's tough and tenaciously grippy Magic Mary and Albert 2.5in tyres. That's a good thing, because the Magura Gustav Pro hydraulic disc brakes need all the traction they can get to deliver their safe, predictable stopping power. There's a remote dropper seatpost, of course, so that you can take the more adventurous line. Sram's XX Eagle Transmission 1x12 gears are driven via a Race Face Era carbon crank – and assistance from Bosch's smooth, quiet CX-R drive and 800Wh PowerTube battery – for quick, precise electronic shifts. With Fox's 38 Factory fork and Float X2 Factory shock delivering 170mm of plush, well-controlled travel at each wheel, it's safe to say that the rest comes down to you. Are you up for it?

Frame description
The Stereo Hybrid ONE77 HPC frame – with 170mm travel front and rear and a mullet wheel set-up 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 then threw in an angle-adjustable headset so that you can tweak the handling to your taste. The 800Wh PowerTube battery sits unobtrusively in the carbon down tube, just above the Bosch CX-R drive. A UDH dropout on the aluminium rear triangle is tough and future-proof, and we also added a Direct Mount chain guide to keep you driving forwards even when the going gets rough.
