When it comes to road bike frame height, this topic encompasses much more than merely the height of the frames used for road bikes. After all, sporty riding has become so enormously popular in recent years (if not in recent decades) that when it comes to frames, you can’t really talk about road bike frames anymore. After all, these frames are used for fixies, cyclocross bikes, and gravel bikes, among others. The road bike (or rather road bike-like bikes) is increasingly used in cities and also on longer tours – because whenever it comes to riding down a longer route, the road bike is the winner among the bike types. What makes the road bike frame above all is the sporty seating position, which is due to the frame geometry of the road bike. Depending on the frame height (and also a variety of other factors), the sitting posture on the bike changes. That is why the fit of the frame to the rider is so enormously important when you are interested in a road bike. How to find the right size road bike and more, here in our guide.
Frame Geometry Road Bike
Since choosing the right frame is about a lot more than just frame height, we’ve collected the frame geometry sizes of 30 different road bike frames. Among the manufacturers of these frames are Scott, Cinelli, Ritchey, Focus, Bianchi, Koga, BMC, Rose, and many more.
With the help of these values, we have created the following table, where you can see the average dimensions for the frame geometry of road bikes. If you compare your own bike to it, you can see how your road bike differs from the average.
|Frame Height||Stacks||Reach||StR Quotient||Head Tube Angle||Seat Tube Angle||Wheelbase|
Tips For Frame Geometry On A Road Bike
When riding a road bike, the main focus is on a relaxed riding position. The most important thing is that the back is straight and the seating position does not cause the rider to hunch back (or cat hump). That would lead to back pain on longer rides. Top tube length is more of secondary concern (is generally much shorter than MTB). We have found that a sufficiently long head tube is usually more important. The head tube has a decisive influence on the seating position, as this is usually decisive for the cant (difference in height between saddle tip and handlebar height). A too strong superelevation – caused by a too-short head tube – sometimes decisively impairs the seating comfort. A suitable cant usually leads to an ergonomically optimal riding position in which you can ride for hours without discomfort – at least as long as your endurance lasts.
Frame Height Road Bike
The frame height generally determines the frame geometry of the bike. As frame height increases, so do all other sizes on the road bike. Therefore, if you can find the right frame height, you will usually already get a suitable road bike. This is the classic approach to finding the right road bike and for the vast majority of cyclists, this already gives you enough information to find the right bike.
But to find the really optimal frame height is not so easy. Because the frame height should not only be determined on the basis of the body size – it is much more about the stride length. And if you want it to be a bit more precise, you have to deal with the stack and reach sizes of the bike.
The sitting posture on the bike is not only influenced by how tall the bike is, but how tall the rider’s stride length is compared to the rest of their body. Using the table above, you can see if you are more of a long-legged rider or a sitting giant in terms of proportions. The table below shows you how the stack reach factor of the bike affects your sitting posture.
Calculate Frame Height
Once you have measured your stride length, you can use our calculator to calculate the appropriate frame height. Since you know the actual length of the rider’s legs based on the stride length, this is the easiest and most effective way to find a suitable bike. This calculator is specifically set for road bikes and is only suitable for bikes with a sporty riding style (road bike, cyclocross, gravel bike, fixie, etc). Basically, your stride length is multiplied by 0.665.
