Cannondale Topstone CAAD Lefty 

Cannondale Topstone CAAD Lefty: Gravel Meets Suspension

The Cannondale Topstone CAAD Lefty is designed for riders who want to go beyond traditional gravel routes. The SmartForm C1 aluminium frame combines strength and precision with the ability to tackle rough terrain, while the Lefty Oliver suspension fork provides an extra level of control on technical sections and challenging gravel roads.

CAAD Frame: Strength and Precision

The SmartForm C1 aluminium frame represents Cannondale's heritage in designing high-performance frames. Its geometry is engineered to combine stability at high speeds with manoeuvrability through tighter sections. Multiple mounting points also allow you to configure the bike for long rides, touring and adventures with bags and accessories.

40 mm Lefty Oliver Fork

The standout feature of this model is the Lefty Oliver fork, with 40 mm of travel, a lockout system and air suspension. Designed specifically for gravel riding, it helps absorb bumps and maintain front-end control over uneven terrain. The 55 mm offset contributes to stable, precise handling without sacrificing the responsiveness needed on more technical sections.

12-Speed Shimano GRX Drivetrain

The Shimano GRX drivetrain combines the GRX 822 rear derailleur and GRX 610 shifters with a 40-tooth chainring. The Shimano SLX 10-51 cassette provides a wide gear range, ideal for tackling demanding climbs, long distances and varied gravel routes. Shimano GRX 410 hydraulic disc brakes complete the setup, delivering controlled and reliable braking.

Tubeless-Ready Wheels and 45 mm Tyres

The WTB ST i25 TCS 2.0 rims are tubeless-ready and paired with WTB Vulpine TCS Light 700x45c tyres. This setup offers a balance of rolling efficiency, grip and comfort, allowing you to tackle different surfaces with confidence.

Ready for Your Most Ambitious Adventures

The Topstone CAAD Lefty features multiple mounting points for bottles and accessories, as well as compatibility with racks, mudguards and a kickstand. Internal cable routing contributes to a clean, streamlined appearance, while the BSA threaded bottom bracket simplifies maintenance.

This is a gravel bike designed for riders seeking greater control on rough terrain, a versatile drivetrain and the freedom to explore routes beyond the tarmac.
