2021 Cannondale Topstone Carbon Gravel Bike, Size M (≈54cm), HollowGram Carbon Wheels

The Cannondale Topstone Carbon is a versatile and fast gravel bike built for riders who want efficiency on pavement and confidence once the road turns rough. With Cannondale’s lightweight carbon frame and carbon fork, this bike balances comfort, stiffness, and durability, making it an excellent choice for long gravel rides, mixed-surface adventures, and even endurance road use.

This setup features a dependable Shimano Ultegra 2x11 drivetrain with a wide 46/30 chainring combo and 11/34 cassette, giving you plenty of range for steep climbs while still maintaining speed on flats. The bike rolls on HollowGram 22 carbon wheels, which significantly improve acceleration and ride feel compared to alloy wheels, and it’s set up tubeless with Vittoria Terreno Dry 38C tires for grip and efficiency on gravel and hardpack.

With under 1,000 miles, this bike is in good pre-owned condition and 100% ride-ready. The only note is some visible sealant on the rear rim, which is purely cosmetic and just needs a quick cleanup. Everything is mechanically sound and ready to go.

Why we love it

We love the Topstone because it’s one of the most well-rounded gravel bikes ever made. It’s light, fast, and comfortable, yet still capable of handling real gravel and mixed terrain without compromise. The HollowGram carbon wheels are a huge upgrade, the Ultegra drivetrain is smooth and reliable, and the geometry makes it easy to ride all day. This is the kind of bike you can train on, explore with, and still line up for gravel events without feeling underbiked.
