Mountain Bike Frame Geometry Explained

Modern bikes favour steeper angles that put the saddle directly over the bottom bracket making pedalling easier and more efficient.

Mountain bike frame geometry explained. The same measurement could also be described as an x small or small medium depending on the manufacturer style of bike or even region the bike is being sold. Most mountain bike manufacturers use classic small medium large sizing. Bicycle frame geometry is particularly important if you re planning on using front and rear loads as. This is the angle of the seat tube relative to the ground.

How are mountain bikes sized. The two most fundamental elements of frame geometry are stack and reach. The long wheelbase and long fork rake will provide additional stability and comfort while riding. Mtb frame geometry explained.

A mountain bike with rear panniers does not actually ride all that different to a touring bike with rear panniers. Experienced mountain bikers already know that frame geometry is important but it s a very complex topic. Welcome to the world s biggest open database of bike geometry. The new standard of stack and reach is the easiest way to start comparing if a bike is going to be long and low or high and short.

If your bike isn t listed yet you can add it. When i m looking at whether a frame geometry is going to fit. Mountain bike geometry explained. A description of the frame size based on this measurement is then allocated for example a manufacturer may measure the seat tube length of a bike as 51cm and then describe it is a small frame.

Mountain bike geometry can be confusing. Find a bike s geometry by name compare different bikes and sizes side by side search for bikes by geometry numbers. For the most part bike frame size is the only thing that changes when you go between sizes things like wheel size suspension and relative geometry number remain the same. What mountain bike frame size should i ride.

You ll commonly hear people say that a bike will do this or that because it has a 65 degree head angle. We look at what chainstay lengths head angles top tube effective virtual seat tubes and how they change a. Knowing the bike s stack how tall a frame is and reach how long a frame is will allow you to compare between different manufacturers and immediately know if it will fit you regardless of how it is described or what the seat tube measurement is. This will help you to better understand the geometry tables of the bikes you are interested in.

But frame geometry can make or break any bike from the outset.
