About the Pinnacle Lithium 1 Part tourer and city bike, part adventurous mountain bike, part flat bar gravel bike. The Pinnacle Lithium 3 Hybrid Bike is your go anywhere ride. If you\\\'re enjoying the adventures of different terrains then you need an adaptable bike which is why the Lithium\\\'s alloy frame is stiff enough to feel responsive while light enough not to hold you back. The robust alloy feel continues through the light and responsive Hi-Ten fork with the added compatibility for mudguards. Keeping you smoothly moving is the Shimano Acera 3x8 Speed Drivetrain, offering up fast, reliable and accurate shifting with enough range to tackle any gradient. Enough space for 2.2 MTB tyres means it\\\'s adaptable for the byways and tracks of country exploration where it feels just as at home as it does on rough UK roads, that come with their own lumps and bumps. If you\\\'re going to be riding all year round then a bike that can tackle the British elements is key. The Lithium comes equipped with Tektro Auriga Hydraulic Disc Brakes giving powerful, controllable and consistent stopping power in all conditions.
