Cannondale Topstone Carbon Lefty 3 Disc Gravel Road Bike 2021

A company project that researched the specific requirements of gravel riding has conceived the Cannondale Topstone Carbon Lefty 3 Disc Gravel Bike. Designed from the ground up, the Topstone Lefty Carbon delivers the pinnacle of performance to all adventure riders who have an unsatisfied desire to explore further and higher into the previously uncharted.

The frame utilises BallisTec Carbon and this material is configured within a size-specific pattern to grant a reactive and positive ride experience. Integrated into this main chassis is the Kingpin suspension configuration that, thanks to the amalgamated specific tube profiles and LockR Pivot system, provides 30mm of plush travel to absorb impacts and increase rear wheel traction. The Lefty Oliver fork then compliments the chassis with its lightweight and stiff suspension construction increasing ride accuracy and control over even the harshest of roads and paths.

The 650b wheelset features WTB alloy rims that are burly and composed with their circumference permitting the use of the ultra-wide 47mm tyres. This tyre width provides all of the grip and control necessary for the heaviest of gravel roads before a robust hubset ensures of low-maintenance and reliability within the harshest of conditions.

Any landscape, from fast roads to technical off-road climbs, can be conquered thanks to the wide-ranging 11-speed cassette with this being actuated by the reliable and crisp gear changes of the Shimano GRX groupset. The consistent and efficient forward drive is then provided by the revered Cannondale crank arms before the fully hydraulic brake system ensures powerful but controlled stopping through any conditions.

The already comprehensive features list is then crowned with a vibration killing Cannondale carbon seatpost, aesthetically pleasing and maintenance-friendly cable routing and full mudguard compatibility for when wet weather protection is required.
