Summary
The Cannondale Topstone is a versatile gravel bike praised for its balanced handling and superb comfort, making it excellent for technical terrain. It features proprietary suspension like the Lefty fork and Kingpin rear system, offering a smooth ride with some limitations on adjustability. However, it is noted for being an evolution rather than a revolution, with a high price point and maintenance considerations for the Lefty fork.

A carbon frame gravel bike with high-end components and sram rival hydraulic disc brakes.
Kingpin suspension improves comfort and handling with minimal weight penalty
Slack head tube angle, dialed suspension, and upright riding position open up possibilities on single track
Does a great job balancing confidence/capability on technical terrain without sacrificing an energetic/responsive ride feel
Lefty Oliver fork is heavy and has inherent compatibility issues
Riders who prefer more traditional road-inspired geometry may find riding position too relaxed

‘Hey, why has your bike only got one leg?’ It’s a question I was asked on more than one occasion
Distinctive looks
Smooth ride quality
Well-balanced steering
Capable design
Suspension saps reactivity
Carries extra weight over simpler designs
Potentially more complex to maintain

It doesn't matter the label on it, the Cannondale Topstone Lefty is the gravel race bike you actually need.

The Topstone Lab71 frameset takes the Topstone and makes it lighter and sharper. It’s a true all-rounder for any gravel escapade.
Lighter and sharper yet stable handling
Exclusive
Could be lighter still without the myriad fittings
Rubber bungs on the fork leg bosses can drop out

Is it all just marketing, or does the Cannondale Topstone Carbon 1 Lefty really have something to offer? And will it reveal its true gravel potential in our group test?
Lefty and KingPin suspension are cool in-house solutions for a little more compliance
Cleverly integrated light and radar thanks to SmartSense
Very balanced and composed handling
Seems restrained overall, despite its versatility

The Cannondale Topstone was already an awesome gravel bike. Now it's even lighter thanks to LAB71 carbon fiber!

Overall, the Cannondale Topstone Carbon Lefty 3 is a fun bike. Yes, a tad on the heavy side, but with some slight changes could be made lighter. Topstone Carbon Lefty 3...
