Understanding Bicycle Stem Length: 90mm vs 110mm
n
Choosing the right stem length for your bicycle can significantly impact your comfort and handling. Two common stem lengths are 90mm and 110mm. But what’s the difference, and which one should you choose? This article breaks down the key considerations to help you make the best decision.
nn
What is a Bicycle Stem?
n
The stem is the component that connects your handlebars to the steerer tube of your fork. It plays a crucial role in determining your riding position and how the bike handles. Stem length is typically measured in millimeters (mm).
nn
90mm Stem: A Shorter Reach
n
A 90mm stem is shorter than a 110mm stem. This means it brings the handlebars closer to you. This can be beneficial if you have a shorter torso or arms, or if you prefer a more upright riding position.
nn
Benefits of a 90mm Stem:
n
- n
- More Upright Position: Reduces reach to the handlebars, making it easier to sit upright.
- Improved Comfort: Can alleviate back and neck pain by reducing strain.
- Enhanced Maneuverability: A shorter stem can make steering feel quicker and more responsive, though sometimes described as ‘twitchy’ (Source 0).

110mm Stem: A Longer Reach
n
A 110mm stem is longer than a 90mm stem, positioning the handlebars further away from you. This is often preferred by riders with longer torsos or arms, or those seeking a more aerodynamic riding position.
nn
Benefits of a 110mm Stem:
n
- n
- Aerodynamic Position: Encourages a more stretched-out, aerodynamic posture.
- Increased Stability: Can provide a more stable feel, particularly at higher speeds.
- Efficient Power Transfer: May allow for a more powerful and efficient pedal stroke for some riders.

Key Differences & Considerations
n
The difference between a 90mm and 110mm stem might seem small, but it can have a noticeable impact on your ride. Here’s what to consider:
nn
- n
- Reach: The most obvious difference is the reach. A 90mm stem shortens the reach, while a 110mm stem lengthens it.
- Handling: Shorter stems can make steering feel quicker, while longer stems can provide more stability.
- Comfort: Your stem length affects your riding posture, which directly impacts comfort.

How to Choose the Right Stem Length
n
There’s no one-size-fits-all answer. The ideal stem length depends on your body proportions, riding style, and bike geometry. Here’s a step-by-step approach:
nn
- n
- Start with Bike Fit: Getting a professional bike fit is the best way to determine the optimal stem length for your body.
- Consider Your Riding Style: If you prioritize comfort and control, a shorter stem might be better. If you want a more aggressive, aerodynamic position, a longer stem might be preferable.
- Experiment: If possible, try riding with different stem lengths to see what feels best. Many bike shops will allow you to test ride bikes with different setups.

The Impact on Bike Handling
n
A shorter stem can make the steering more responsive, sometimes even described as ‘twitchy’. Conversely, a longer stem often provides a more stable feel, especially at higher speeds (Source 0). It’s important to find a balance that suits your preferences and riding conditions.
nn
Stem Length and Frame Size
n
Bike manufacturers often equip bikes with stems that are appropriate for the frame size. Road bikes typically come with stems ranging from 80mm to 120mm. Size medium bikes often have 100mm or 110mm stems (Source 4). However, this is just a starting point. You may still need to adjust the stem length to achieve your ideal fit.
nn
The “Sweet Spot” Myth
n
While some say the “sweet spot” for road bike stem length is 100mm to 120mm (Source 2), that doesn’t mean it’s right for everyone. Don’t be afraid to deviate from this range if it improves your comfort and performance.
nn
Can You Feel the Difference?
n
Yes, you should feel the difference between a 90mm and 100mm stem (Source 3). The change in reach and handling will be noticeable. However, the stem length doesn’t affect stiffness or handling in terms of frame performance, just the rider’s position and control.
nn
Adjustable Stems: A Useful Tool?
n
Adjustable stems can be helpful for experimenting with different stem lengths and angles. They allow you to fine-tune your riding position without having to purchase multiple stems. However, some riders prefer the stiffness and lighter weight of a fixed-length stem once they’ve found their ideal fit.
nn
Final Thoughts
n
Choosing between a 90mm and 110mm stem is a personal decision based on your individual needs and preferences. Consider your body proportions, riding style, and handling preferences. If possible, get a professional bike fit or experiment with different stem lengths to find the perfect fit for you.
