Summary

It features a refined design with improved suspension, including the Lefty Oliver fork and Kingpin rear system, providing a smooth and controlled experience over rough surfaces.

Aug 2025
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

Cannondale's Topstone Lefty has always lived in its own category; part gravel bike, part specific race bike, part drop-bar MTB experiment.

‘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
May 2025 · Josh Ross
It doesn't matter the label on it, the Cannondale Topstone Lefty is the gravel race bike you actually need.

Mar 2025 · Warren Rossiter
The new 2025 Topstone Carbon delivers a class-leading technical-terrain gravel ride, but are the small updates enough to justify an upgrade?
Extremely balanced handling
Superb comfort
Great control over technical terrain
Udh dropouts
Stash port
Big tyre clearance
Not enough of an upgrade over the current bike to justify a change

Mar 2025 · Calvin Zajac
The 2025 Cannondale Topstone Carbon is designed to be the ultimate gravel weapon – but can it deliver on the trail with all its technical sophistication?
Excellent compliance thanks to Lefty Oliver and KingPin
Playful and intuitive handling
High versatility
Downtube storage compartment
At 9.88 kg, it’s on the heavier side for a gravel bike
Lefty Oliver fork limits tire clearance
