The Topstone CAAD Lefty is the most capable bike in the new aluminium Topstone range, and the one that makes rough gravel feel like fair game. It pairs the premium SmartForm C1 alloy frame with a Lefty Oliver suspension fork, giving you 40mm of gravel-tuned travel up front for more grip, more control and less fatigue when the surface turns loose, rutted or broken.
The frame is built with everything Cannondale has learned from decades of CAAD aluminium: custom-butted and swaged tubes, smooth welds and a lifetime warranty. OutFront Steering Geometry pairs a longer fork offset with a slack head angle, so the bike feels calm at speed but still turns quickly on tight singletrack, and there's room for tyres up to 47mm with the Lefty fitted.
Shimano's GRX 610 1x12 drivetrain keeps things simple, with a 40T chainring and a 10-51 cassette that gives you a proper low gear for steep, loose climbs. GRX hydraulic disc brakes, WTB ST i25 tubeless-ready wheels and 45mm WTB Vulpine tyres complete a build that's ready for big days off the beaten track.
