Cannondale's attention to detail on the Topstone is excellent, and they've made some really interesting design choices to stand out in an increasingly-crowded category. Apparently they've succeeded -- the Topstone 105 has been the third most popular bike on all of 99 Spokes this year.
Well balanced
Descends well
Good power transfer
No mount points on the fork
Cheap bottom bracket

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 2 L is the second version of the brand’s general-remit gravel bike. Cannondale has the SuperSix Evo
Kingpin creates comfort without complication
Confident handling
Solid spec
Modifiable design
Weight
Messy front end cable routing
Debatable application of SmartSense

Go-anywhere gravel bike with on-road manners
Fun, inspiring handling
Comfort via Cannondale's Kingpin suspension
Integrated lights for road riding or commuting
Integrated lights aren’t to everyone’s taste or powerful enough for off-road riding

I tested the Topstone with a Lefty Oliver fork while road riding, gravel cycling, and underbiking around Aspen, Colorado.

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...

Fast, light gravel ripper with top-notch equipment and useful suspension tech
Suspension a genuine benefit off road
Fast and fun ride
Dropper and mudguard compatible
Fiddly front wheel removal
Tyres not up to technical stuff
Costs large amounts of money
Sep 2020 · James Stout
Tons of fun - though we'd like a little more tyre clearance for techy trails, please
Fork is excellent
Balanced and responsive handling
Lefty hub limits wheel choice
Would like more clearance
