The head tube is the part of the frame that extends from the wheel fork up to the handlebar. They are the head tube and the bottom bracket.

The body should lean 40-50 degrees, arms should be parallel and relaxed, and the handlebar should be easy to turn.īefore measuring the reach and stack it is important to locate the two main points on the bike from which these measurements are taken. To choose mountain bike reach, stay seated on the bike saddle with one foot on the pedal, then stretch the arms and hold the handlebar grips. To calculate mountain bike reach, measure the horizontal distance from the top of the center of the head tube to the vertical line that runs from the center of the bike's bottom bracket. Even if you failed geometry in high school, don’t worry this crucial mountain bike geometry is not difficult and when done methodically you can easily use a mountain bike reach calculator to figure things out. Calculating the mountain bike inner-frame length (also known as reach), as well as center point height (known as stack) is the simplest method to avoid discomfort and muscle fatigue when riding.

Measuring your mountain bike properly will help you determine if your bike is correctly sized to your body, as well as the length and angle adjustments you will need to make to obtain optimal comfort and control when riding. Mountain Bike Reach Calculator and Tips/Tricks to Alter Bike Reach
