Cannondale Topstone Carbon Lefty 1 Disc Gravel Bike 2021

CANNONDALE TOPSTONE CARBON LEFTY 1 DISC GRAVEL ROAD BIKE 2021

The Cannondale Topstone Carbon Lefty 1 Disc Gravel Road Bike has been conceived via a brand new project with the aim of creating the ultimate gravel adventure bike. Blending a comprehensive gamut of advanced materials and technologies the Topstone Lefty furthers exploration into the previous unknown.

The frame is constructed from BallisTec Carbon to naturally afford a snappy and responsive ride. This material is laid within a specific pattern across each tube section to custom-tune the ride sensation by size before an innovative Kingpin suspension design is seamlessly integrated into the rear triangle configuration. This dampening arrangement offers up to 30mm of travel but, thanks to its LockR Pivot system, guarantees reactive forward drive with every pedal stroke. The Lefty fork then compliments by offering bump-taming compliance within a stiff and lightweight structure for optimally precise handling, even across the most technical of surfaces.

The wheelset is born from Cannondale's own composite knowledge and features a carbon rim layup that grants strength, low weight and rough surface compliance. A 23mm internal width ensures that big volume tyres can be seated with increased sidewall support before DT Swiss hub internals provide smooth spinning and robust bearings. 650b x 47mm WTB tyres then offer maximum traction, cornering grip and plush levels of comfort via their capacious air volume.

Any topography can be conquered thanks to the vast range of gears provided by the 12-speed cassette and these are actuated with preciseness by the SRAM AXS wireless, electronic groupset. A fully hydraulic brake system provides modulated and powerful stopping within any conditions before a carbon Hollowgram finishing kit and mudguard compatibility complete a thoroughly comprehensive gravel package.
