Cannondale Topstone CAAD 1 GRX 1x Bicycle – Aluminum Gravel Bike

Cannondale Topstone CAAD 1 GRX 1x: Always Ready for Adventure

The Cannondale Topstone CAAD 1 GRX 1x is a high-performance aluminum gravel bike designed for those who love exploring new horizons, riding less-traveled roads, and tackling daily commutes with greater dynamism. The premium SmartForm C1 aluminum frame, all-carbon fork, and 12-speed Shimano GRX drivetrain offer a combination of strength, control, and versatility, ideal for mixed terrain and long distances.

The single-ring configuration simplifies gear management and makes pedaling intuitive on different types of terrain. The 40-tooth Shimano GRX crankset, paired with the 12-speed Shimano SLX 10-51 cassette, provides a wide range of gears for tackling both fast sections and the most challenging climbs.

The WTB ST i25 TCS 2.0 wheels and 700x45c WTB Vulpine TCS Light tires ensure a balance between rolling efficiency and grip. The carbon fork helps keep the weight down and improve comfort, while the Cannondale Conceal system keeps the handlebar area clean and integrated.

Thanks to the rear tire clearance of up to 52 mm and 56 mm at the front, measured according to the manufacturer's specifications, and the numerous mounting points for water bottles and accessories, the Cannondale Topstone CAAD 1 GRX 1x is ready for sporty gravel rides, multi-day adventures, and daily commutes.

A Complete Guide to Bike Sizes

Foreword: Not all bike sizes are the same

Each type of bike has a specific frame and often uses a different size scale. For example, a road bike with a 54cm frame might be considered a medium size by one brand, but a large by another.

Bicycle adjustment margins

Some types of bikes, like gravel bikes, offer a wide range of adjustments, adapting to different body types. Other models, however, have limitations in this regard. This is an important aspect to consider.

How to use size charts

We've created a simple guide to help you find the right bike size:

1. Check out our size charts for each bike type.

Size Charts: Find Your Perfect Bike

Gravel and road bikes

Sizes are based on the length of the top tube (in cm), which determines the reach of the bike.

For gravel, measurements may vary slightly due to different geometries, but remain similar.

Mountain bike

MTBs are measured in inches, based on the seat tube.

Sizes also vary depending on the type of MTB: full-suspension , hardtail or fat bike .
