The hills are calling, and that means you need a bike that's up to the job. The Stereo Hybrid 140 HPC Pro 750's fourth-generation Bosch CX motor and 750Wh battery won't let you down. Paired with the reliable shifting and wide range of Shimano's Deore 1x11 gears, it'll make light work of any climb. And for the way back down you've 150mm of travel from the RockShox Recon Silver air fork up front, paired with 140mm from the RockShox Deluxe Select shock at the rear. Grippy Schwalbe 2.6in tyres hook you up to the trail, while powerful Magura MT Thirty hydraulic disc brakes with four-piston calipers and 203mm rotors ensure you're always in full control. It's up for it. Are you?Evolution never stops. That's why, across all frames in our SizeSplit system, the Stereo Hybrid 140 HPC now features the ability to house up to a 750Wh battery under its dust- and splash-proof cover. It means you can power the fourth-generation Bosch CX drive unit – with 85Nm of hill-devouring torque – on long rides, whatever frame size fits you best. The Boost 148 rear axle, large pivot bearings and All Mountain Geometry deliver assured handling, even when you're exploring the limits of the 140mm rear and 150mm front travel. Sram's UDH gear hanger helps protect against crash damage and is easily replaceable. And Integrated Cable Routing reduces maintenance and complements the clean lines of the full carbon main frame.
