Cannondale Topstone Neo Carbon 1 Lefty Disc Electric Gravel Road Bike 2021
The Cannondale Topstone Neo Carbon 1 Lefty Disc Electric Gravel Bike is an all-purpose gravel explorer that is destined for the greatest of adventures deep into the wilderness thanks to an exhaustive collection of design features and technologies.
The discreet but efficient Bosch motor system provides power assistance and longevity to facilitate deeper and higher exploration and this is amalgamated seamlessly into Cannondale’s finest carbon gravel bike chassis. This bike has an electric assisted speed limit of 15.5 mph / 25 km/h. The nimble and responsive frame configuration features a specific composite layup and Kingpin LockR suspension to deliver an ultimately accurate and smooth ride across even the most technical of surfaces. The Lefty Oliver fork then supplements with its carbon construction and 30mm of plush travel delivering line precision and control for when the paths are at their most unforgiving.
The WTB alloy rims are reliable and sturdy and are laced to robust hub shells by 32 stainless spokes to deliver a wheelset primed for the rough stuff. The 650b arrangement of these wheels then matches perfectly with the voluminous 42mm wide tyres to provide confidence and traction even over the loosest of paths.
Any topography can be conquered thanks to the huge range of ratios provided by the 12-speed cassette with this being flicked through with aplomb by the wireless, electronic SRAM AXS groupset. A hydraulic brake system then provides powerful stopping within a composed manner no matter the conditions or terrain.
The build is then rounded off perfectly by the internal cable routing that is aesthetically pleasing and maintenance-friendly, full mudguard eyes for when the skies open and dropper post compatibility for technical riding situations.
