Cannondale Topstone Carbon 1 AXS Gravel Bike

Designed for riders who never turn back, the Cannondale Topstone Carbon 1 AXS is a true all-round gravel bike built for endless exploration. From rocky singletrack to flowing fire roads, this bike delivers confidence and capability with every pedal stroke.

At its heart is a lightweight full carbon frameset, complete with Kingpin rear suspension for extra traction and comfort over rough terrain. Proportional Response construction ensures each frame size is tuned for optimal performance, while the StashPort downtube storage keeps essentials close without disrupting the ride.

SRAM’s Rival XPLR AXS 13-speed wireless groupset delivers smooth, intuitive shifting, and the Reserve 40|44 GR carbon wheels with DT Swiss 350 hubs provide responsive handling and durability across every surface. WTB Vulpine 45c tyres grip confidently whether the path is dry, loose or muddy.

Comfort is enhanced by Cannondale’s SAVE carbon seatpost and Easton EA70 AX flared bars, while the integrated Wheel Sensor connects with the Cannondale App to track ride stats, route details and service intervals with precision.

I’m really pleased with the Cannondale Topstone Carbon 1 AXS Gravel Bike, and the sale price made it an even better value. The bike feels smooth and efficient on tarmac, and it’s equally composed and sure‑footed when the terrain gets rougher, which has made my early rides genuinely enjoyable. The build quality and overall feel inspire confidence, which is exactly what I was hoping for in a gravel bike. Big thanks to Ian for the great service throughout the process - he was helpful, straightforward, and made the whole purchase experience stress‑free from start to finish.

1 question answered

  1. What is the weight for size 54cm

    Asked by Steff (Birmingham) —

    1. Hi Steff, I'm afraid Cannondale don't publish a per-size weight for the Topstone Carbon 1 AXS, so we can't give a confirmed figure for the 54 cm. For the exact weight, the surest route is to get in touch via https://www.sigmasports.com/contact-us and we can check with Cannondale for you. Many thanks Joe W
