How to find your Canyon road bike size

Finding your road bike size is easy with just a couple of measurements:

• Your height
• Your inside leg length

Once you have these numbers, use the bike size calculator on each bike's product page to find your perfect fit.

Knowing your road bike size begins by looking closely at the bike's geometry. Head over to our road bike geometry explainer for more information. It's an easy read if you're not familiar with the minutiae of bike size charts. The article is also a great refresher if it's been a while since you bought a bike

Geometry has evolved over the years and bike manufacturers have their own signature style and proprietary technology they incorporate into their bikes. Even the geometry of road bike models from the same manufacturer can differ: an aero road bike has a different geometry to an endurance road bike, for example.

That said, a bike has to look like a bike and function as a bike in order to be a bike, so there’s only so much variation.

Since bike sizing varies, the most useful measurements on a road bike size chart tend to be:

• Seat tube length
• Stack
• Reach

Traditionally, a frame size was based around top tube length. Numbers such as 52, 54, 56, 58 etc correlated to the length of the seat tube. Modern road bikes have varying head tube and seat tube angles and lengths, which are important considerations when sizing up your new road bike. For this reason, a lot of manufacturers including us here at Canyon have changed our sizing method. Instead of numbers, we use letters to indicate the size as shown below.

We're proud to stock one of the largest bike size ranges in the industry. As a general rule of thumb, our bike sizes are split into the following sizes by height:

• 3XS: 152cm - 160cm
• 2XS: 160cm - 166cm
• XS: 166cm - 172cm
• S: 172cm - 178cm
• M: 178cm - 184cm
• L: 184cm - 190cm
• XL: 190cm - 196cm
• 2XL: 196cm - 204cm

We no longer stock women's specific road bikes, however our wide range of sizes means there's a bike out there for every body, no matter your sex. For more information on this, you can read what Canyon’s Road Product Manager Dan Heyder says in our bike sizing article.

Though your physiology will define what size road bike you should ride, sometimes personal preference is important. If you find that your size falls in between bike frame sizes, we recommend reviewing the road bike size chart a little more closely.

On Canyon's bike size charts, you'll also find Stack+ and Reach+. These measurements are more effective numbers and take into account a bike's spacers and supplied stem.

A longer reach means you'll be more stretched out when you ride. A higher stack means a more upright riding position. These two important measurements help you figure out your riding position on the road bike.

At this point in the bike sizing process, you should also consider your own physiology. Think about your flexibility and any previous injuries you've had. Are you able to sustain low, aerodynamic riding positions for long periods of time? If not, you might want to look for a bike with slightly higher stack.

If you're thinking of riding longer distances, a more comfortable bike will be more forgiving.

There are many ways to tweak the size of your road bike to make it a little more comfortable. The main contact points on the bike are the most important parts to get right. Swapping your saddle and its position can improve your comfort and enjoyment of riding straight away.

Other optional adjustments include changing the stem for a longer or shorter reach, and adding spacers to raise your bars for a higher stack. Small changes can result in great differences, so make changes gradually. You can find some alternatives for the contact points in our online shop.

We're confident you will find the perfect size road bike at Canyon. Follow these simple steps to find your ideal road bike size:

• Measure your height and inner leg length (double check it!) and use the calculator on the product page
• Check the Stack+ and Reach+ to make sure you’ll be comfortable
• Consider adjustments you can make to your bike to hone the fit
• Check in with a professional bike fitter for their opinion
• Order your road bike and ride!

If you're between sizes, take a closer look at the geometry chart. If you’re still stuck, we are happy to help you make the right decision. Check our events pages and social media channels for information about test rides in your area.

You can also find a professional bike fitter who can help your find the perfect road bike size. A simple Google search will return your nearest bike fitter. These specialists take into account your overall health, fitness and physiology to provide optimum measurements on your new road bike.
