Replace your suspension fork - which fork fits your bike?
Would you like to replace your suspension fork but are unsure which one really fits? Then you've come to the right place.
For the new fork to fit your bike without any problems, there are four key points you need to pay attention to: wheel size, travel, steerer tube, and axle size.
In this guide, we show you step by step how to find the right suspension fork and avoid typical mistakes.
- Check the wheel size
- Compare the travel
- Determine the steerer tube
- Measure the axle size
1. Wheel size - the most important foundation
The wheel size of your new suspension fork must match your wheel.
Typical sizes are:
- 26 inches
- 27.5 inches
- 29 inches
👉 You can find the size directly on the tire or rim.
Important: The wrong wheel size means that the wheel will not fit correctly in the fork.
2. Travel - important for geometry & handling
The travel must also match the existing fork.
This is specified in millimeters and can usually be read directly on the fork.
In our example, the fork has 200 mm of travel.
A significantly different amount of travel changes your bike's geometry and therefore also its handling.
3. Steerer tube - straight or tapered?
There are two variants of steerer tube:
- Straight steerer tube
- Tapered steerer tube
The tapered steerer tube is wider at the bottom than at the top.
👉 This is not always immediately apparent from the outside. It is therefore best to briefly remove the old fork and check.
If the steerer tube becomes significantly thicker toward the bottom, it is a tapered steerer tube.
4. Axle size - often the source of errors
The new suspension fork must of course also fit the axle and the wheel.
To do this, you should briefly remove the wheel and measure two things:
- Distance between the fork ends
- Axle diameter
A typical modern size is:
- 15 x 110 mm → Boost
👉 This means:
- 15 mm axle diameter
- 110 mm axle width
The fork's axle size must match the wheel exactly.

Typical mistakes when buying a suspension fork
- ❌ Wrong wheel size selected
- ❌ Axle size not checked
- ❌ Wrong steerer tube
- ❌ Travel changed significantly
Conclusion
If the wheel size, travel, steerer tube, and axle size match, you can easily install your new suspension fork.
With the right measurements, you can avoid buying the wrong parts and quickly find the right fork for your bike.
