One of the most significant changes to your ride is switching stems. There are many reasons to do so, and one is mostly for comfort. Others are performance. But it would be best if you always considered safety first.

Here is another example of a stem not installed correctly. Installing a stem incorrectly can cause the stem to fail and you to crash. Just imagine that you’re flying done that favorite hill 30-40mph, and then your bars pop off the bike. Your weight has you crashing forward, and all in a blink of an eye, you’re tumbling to the ground. Scary!

Stack height is something so simple can be overlooked. When looking at the top bolt of the stem, and how it is over the edge of the fork’s steer tube. This means that the stem only has one bolt clamped and at an awkward position. The fix is to remove one of the spacers or flip the spacer to the top so the stem bolts are both under the rim of the fork steer tube. Always make sure the binder bolts of the stem are always under the rim of the fork steer tube. Yes, you lose a couple of mm in stack height, but look for a different stem or extender if you are still not high enough.
