The road bike frame size guide is an essential element to finding the right bike for you. Whether you’re just getting into cycling or a seasoned pro, knowing what size road bike frame you should get makes a world of difference in how much enjoyment you get out of riding.
Road bikes are generally measured by the size of the frame (measured from the center of the bottom bracket to the center if the top tube). This measurement is commonly referred to as the standover height. The standover height helps to determine the frame size category that will best suit your body size and cycling goals.
Your bike frame should be size-specific based on your height and skill level. A rider’s height will vary significantly according to their inseam, which will determine the optimal standover height for the frame you choose. It’s best to get fitted for a bike before buying, as the frame size should be tailored to fit the individual’s needs and goals.
To figure out what the best road bike frame size for you should be, first measure your total height – from the floor to the top of your head – and your inseam. Once you have these measurements, the following are some general rules of thumb for selecting the most appropriate frame size based on your height:
If your height is under 5’1”, you should opt for an extra-small bike frame with standover heights ranging from 25.5” to 27”.
If you’re between 5’1” and 5’7”, a small road bike frame with a standover height of 28” to 30” is ideal.
For riders 5’7” to 5’11”, a medium bike frame with standover heights of 30.5” to 32” is usually best.
If you’re between 5’11” and 6’3”, you want a large frame with a standover height of 32.5” to 34”.
Riders taller than 6’3” should choose an extra-large bike frame with standover heights between 34.5” and 36”.
If you measure yourself correctly and use the above guide to select the right frame size, you should have no problem finding the road bike frame that fits your body perfectly and allows you to enjoy the best cycling experience possible.
In addition to the above sizing guidelines, most experienced riders suggest choosing a frame size that’s one size larger than your height suggests. This is recommended for two reasons:
1. First, a larger frame provides most riders with greater maneuverability and stability on the bike.
2. Second, it gives you room to make your bike more comfortable over time. When you upgrade your bike components, you may need to move the seat and handlebars a bit more, and this is easier with a larger frame size.
Protip: You should consider the type of riding you intend to do before selecting your frame size. For competitions, such as triathlons, you’ll want a frame that’s slightly smaller for extra speed and maneuverability. If you’re more interested in touring, you may opt for a larger frame than what you need for a road race scenario.
Whatever the case, the most important factor is that the frame size fits your body and you’re comfortable on your bike. To ensure this happens, it’s best to get professionally fitted by a knowledgeable cycling professional or retailer who can help you find the best fit for your body and the type of cycling you’ll be participating in.
Ultimately, it’s up to you to find the right road bike frame size guide that will suit your body and biking goals. With proper measuring, research, and guidance from professionals, you can find the frame size that fits the type of biking you’ll enjoy most.
