There’s no definitive answer to the question of how much steerer tube should be above your stem, but there are a few things to keep in mind when making your decision. First, the amount of steerer tube that’s above the stem will affect the bike’s handling. A taller stack height will make the bike more stable, while a shorter stack height will make the bike more agile.
Second, the amount of steerer tube that’s above the stem will also affect the bike’s fit. If you have a long torso, you’ll likely need a taller stack height to get the bars in the right position. Conversely, if you have a short torso, you may need a shorter stack height to avoid feeling too stretched out.
Finally, keep in mind that most stems have a minimum insertion mark that indicates how much steerer tube must be above the stem to avoid damaging the fork.
If you’re looking for a general rule of thumb, most people say that you should have at least 2 inches of steerer tube above your stem. This gives you enough room to make any necessary adjustments, and also provides a little bit of wiggle room in case you need to make a quick change on the trail. Of course, there are always exceptions to the rule, so be sure to consult your bike’s owners manual before making any changes.
How To Cut A Road Bike Steerer Tube
How short should you cut your steerer tube?
It’s generally recommended that you leave about 3-5mm of steerer tube above the top of your stem. This will give you some wiggle room in case you need to make adjustments, and it also helps to prevent your stem from slipping. If you cut your steerer tube too short, you may not be able to make any adjustments, and your stem could slip, which could be dangerous.
So, err on the side of caution and don’t cut your steerer tube too short.
Do you need spacers above stem?
No, you do not need spacers above stem. Stem spacers are used to keep the stem from coming into contact with the steerer tube, which can damage the steerer tube. Stem spacers also help to keep the stem from slipping on the steerer tube.
What length steerer tube do I need?
If you’re not sure what length steerer tube you need, there are a few things you can do to figure it out. First, you’ll need to know the make and model of your bike, as well as the type of forks you have. You can usually find this information stamped on the bottom of your forks.
Once you have that information, you can look up the recommended steerer tube length for your bike.
If you’re still not sure, or if you can’t find the information you need, you can always measure the steerer tube on your current bike. To do this, you’ll need to remove the fork from the frame.
Once the fork is removed, measure the steerer tube from the top of the crown race to the bottom of the steerer tube where it meets the fork crown. That measurement will give you the minimum length steerer tube you need.
How do you measure a steerer tube stem?
When you go to buy a new stem, the first thing you need to do is measure the steerer tube on your bike. The steerer tube is the metal tube that sticks up out of the frame and holds the fork in place. The stem attaches to the steerer tube and extends out to the handlebars.
Most steerer tubes are either 1 inch or 1 1/8 inches in diameter, but there are a few different sizes out there. To measure the steerer tube, you will need a tape measure and a ruler or a caliper.
First, find the top of the steerer tube.
It should be level with the top of the headtube. If it is not, you will need to measure from the top of the headtube to the top of the steerer tube. Once you have found the top of the steerer tube, measure the diameter of the steerer tube using the tape measure.

Maximum steerer tube length
If you’re looking to upgrade your mountain bike, one of the first things you’ll need to consider is the steerer tube length. The steerer tube is the part of the fork that extends up into the frame, and its length will dictate how much travel your bike has.
Most mountain bikes have a steerer tube that is between 120 and 140mm long.
If you’re looking to increase the travel on your bike, you’ll need to get a fork with a longer steerer tube. For example, a 150mm steerer tube will give you an extra 10mm of travel.
When choosing a new fork, it’s important to make sure that the steerer tube will fit into your frame.
If it’s too long, you won’t be able to install the fork properly. If it’s too short, you’ll decrease the amount of travel your bike has.
Conclusion
In order to answer how much steerer tube should be above the stem, we need to know a few things. The stem is the part of the bicycle that connects the fork to the handlebars. The steerer tube is the part of the fork that goes through the stem.
The headset is the part that connects the steerer tube to the frame.
The amount of steerer tube that should be above the stem depends on the type of bicycle and the type of stem. A road bicycle with a quill stem will have less steerer tube above the stem than a mountain bicycle with a threadless stem.
A stem that is raised or angled up will require more steerer tube above it.
If the steerer tube is too short, the stem will not be able to be raised high enough. This can cause the handlebars to hit the rider in the chest in a crash.
