Cyclocross bikes are generally the same size as road bikes, with a few important exceptions. The main difference is that cyclocross bikes have a higher bottom bracket to allow for more clearance over obstacles, and they also have longer chainstays to accommodate wider tires. Other than that, they should fit pretty much the same as a road bike.
Here is the cyclocross bike size chart:
| Rider Size | Bike Sizes | Bike Size (cm) |
| 155-160 cm | XS | 47-49 cm |
| 160-165 cm | Small | 49-51 cm |
| 165-170 cm | Small/M | 51-53 cm |
| 170-175 cm | Medium | 53-55 cm |
| 175-180 cm | Large | 55-57 cm |
| 180-185 cm | Large/XL | 57-60 cm |
| 185-190 cm | XL | 60-62 cm |
Here are a few other things to keep in mind when sizing a cyclocross bike:
- Cyclocross bikes tend to have a higher bottom bracket than road bikes, so you may need to size up if you’re used to riding road bikes.
- Cyclocross bikes also tend to have longer chainstays, so you may need to size down if you’re used to riding mountain bikes.
- Most cyclocross bikes will have cantilever brakes, which require slightly longer reach levers than disc brakes. You May need to size up if you’re used to riding disc-brake equipped bikes.
What is Cyclocross?
Cyclocross is a type of bicycle racing that is typically held in the fall and winter (the off-season for road racing) on a variety of surfaces including grass, dirt, sand, wooded trails, and sometimes even snow.
Cyclocross courses are typically 1.5-2 miles long, with a variety of obstacles including barriers that riders must dismount and run over, sand pits, and stair runs. Because cyclocross is so varied, it is important to have a bike that can handle all types of terrain and conditions.
key things to look for when choosing a cyclocross bike:
Frame material: Most cyclocross frames are made from either aluminum or carbon fiber. Aluminum frames are typically more affordable, but carbon fiber frames are lighter and offer better power transfer.
Wheel size: Cyclocross bikes usually come with 700c wheels, but some smaller riders may prefer 650c wheels for a better fit.
Tire width: Cyclocross tires range in width from 30mm to 45mm. Wider tires offer more traction and stability on rough terrain, but they also add weight and rolling resistance. Choose narrower tires if you do most of your riding on groomed courses.
Brakes: Cyclocross bikes can be equipped with either cantilever or disc brakes. Disc brakes offer more stopping power in wet or muddy conditions, but they also add weight and can be more difficult to service. Cantilever brakes are lighter and easier to maintain, but they may not offer enough power in extremely muddy conditions.
The Benefits of Cyclocross
Cyclocross races are run on a variety of terrain, from grass to sand to mud, and frequently include obstacles that riders must dismount and navigate on foot.
This makes cyclocross an excellent disciplines for building bike handling skills and overall fitness. The fast-paced, tactical nature of cyclocross also makes it great fun to watch.
The Different Types of Cyclocross Bikes
Cyclocross bikes are designed for a specific type of racing that is held on a short course that features a variety of terrain, including grass, mud, sand, and pavement. These races are typically held in the fall and winter when road racing is not as popular. Cyclocross bikes are different from road bikes in a few key ways.
First, cyclocross bikes have a more robust frame and fork to handle the rigors of off-road riding and racing. They also have wider tires than road bikes, which gives them more traction on loose or slippery surfaces. In addition, cyclocross bikes typically have cantilever or disc brakes to provide better stopping power in wet or muddy conditions.
There are three basic types of cyclocross bikes: race bikes, all-purpose/utility bikes, and adventure/touring bikes. Race bikes are designed for competitive racing and have features that make them lighter and faster, such as lighter weight frames and components, tighter tire clearances, and higher bottom bracket heights for improved pedaling efficiency.
All-purpose/utility bikes are designed for riders who want a bike that can do it all—they’re great for racing, training rides, commuting, gravel grinding, and even light off-road riding. Adventure/touring bikes are designed for riders who want to explore beyond the pavement—they’re equipped with wider tires and more versatile gearing to tackle dirt roads and trails.
If you’re interested in cyclocross racing or simply want a versatile bike that can handle a variety of riding surfaces, a cyclocross bike may be the right choice for you. Use this guide to learn more about the different types of cyclocross bikes and find the perfect one for your needs.
How to Choose the Right Size Cyclocross Bike
Cyclocross bikes are designed for versatility and functionality, with a frame geometry that is somewhere between a road bike and a mountain bike. They usually have wider tyres than road bikes, and are capable of riding on rougher terrain.
When choosing the right size cyclocross bike, it’s important to consider the type of riding you’ll be doing. If you’re mostly going to be riding on the road, then you’ll want to choose a size that is similar to a road bike. If you’re planning on doing more off-road riding, then you might want to size up to a mountain bike.
The other thing to consider is the width of the tyres. Cyclocross bikes can come with either 700c or 650b tyres. The 700c tyres are typically narrower and are better suited for riding on the road, while the 650b tyres are wider and can handle more off-road terrain.
To help you choose the right size cyclocross bike, we’ve put together this handy size chart. Simply find your height in the chart and then match it up to the corresponding cyclocross bike size.
If you’re between sizes, or if you plan on doing a mix of road and off-road riding, then it’s best to err on the side of caution and go with the larger size.
Conclusion
At the end of the day, what bike you buy is up to you and only you. The best thing you can do is go to a local bike shop and talk to them about what bike would be best for your needs. They will be able to help you make a decision based on your budget, riding style, and goals.
