How Are Road Bike Stems Measured
Road bike stems are measured from center to center. This means that the measurement is taken from the center of the stem clamp to the center of the steerer tube. This is important to know when you’re looking for a new stem, as you need to make sure that the stem you choose will fit your bike.
How to Measure Your Road Bike Stem for the Perfect Fit
To measure your road bike stem, you will need a ruler or tape measure and a bike that is in good working order.
1. Stand over the bike with your feet flat on the ground.
2. Place the ruler or tape measure on the top of the head tube, just below the stem.
3. Measure from the center of the stem to the center of the handlebars.
4. Repeat steps 1-3 for the other side of the bike.
5. Add the two measurements together to get your total stem length.
Your stem length should be between 80mm and 130mm, depending on your height and riding style. If you are unsure of what stem length is right for you, consult with a bike shop professional.
How are Road Bike Stems Measured?
The Different Stem Measurements
There are three main measurements to consider when choosing a road bike stem:
Stack height: This is the vertical distance from the center of the steerer tube to the top of the stem.
Reach: This is the horizontal distance from the center of the steerer tube to the center of the handlebar clamp.
Angle: This is the angle of the stem, measured from the horizontal.
Choosing the Right Stem Measurements
The best way to choose the right stem measurements for your bike is to experiment with different combinations until you find a setup that feels comfortable and allows you to control the bike effectively.
Here are a few things to keep in mind when choosing stem measurements:
Your height and reach: The taller you are, the longer your reach will be, and the shorter your stem will need to be.
Your riding style: If you ride in a more upright position, you will need a shorter stem. If you ride in a more aggressive position, you will need a longer stem.
The type of bike you ride: Road bikes with shorter wheelbases typically require shorter stems, while road bikes with longer wheelbases typically require longer stems.
Stem Height and Reach Calculators
If you’re not sure where to start, there are a number of online stem height and reach calculators that can help you find a starting point. These calculators typically ask for your height, inseam, and riding style, and then they generate a recommendation for stem measurements.
Here are a few popular stem height and reach calculators:
