Choosing the right mountain bike size is vital for comfort and performance. Follow our guide to find your fit and avoid mistakes!
Finding the perfect size is key to comfort and performance. A well-fitted bike prevents injury and ensures a great ride. Ready? Follow these steps to find the mountain bike size that is right for you.
Before choosing the right mountain bike size, it's essential to measure yourself accurately.
Right, so you now know your size! Now, with the measurement you’ve taken, the simplest step is to refer to the size guide that matches your MTB style.
There are specific size guides depending on your mountain biking discipline: Are you more into trail, cross country or all mountain mountain bike riding?
Quick tip: To ensure the frame fits, mount the bike and place your feet flat on the ground. The bottom of your inseam should be six to eight centimetres above the top tube of the frame.
The mountain bike sizes we recommend are indicative and are specifically tailored for Rockrider MTB models. These sizes may vary depending on your body shape or be adjusted with steering components (like the stem or seat post).
Some MTB models do not offer XS or S sizes. Be sure to check the size availability either on the website or in-store.
Don’t worry, it's not a problem! To help you choose between two MTB sizes, consider your riding style.
Trail MTB or All-Mountain MTB:
If you're looking for comfort and ease of handling, go for the smaller size, which will give you a more upright riding position.
If you want to optimize your performance and pedalling efficiency, choose the larger size, which will offer a more extended riding position.
Cross-Country MTB:
Opt for the exact recommended size to enhance your performance and stability.
If you're looking for a more precise size for your mountain bike, another useful measurement is your inseam. Since your torso and leg lengths may vary, measuring your inseam can provide a more accurate indication of the right MTB size for you.
- Just like when you measured your height, stand upright, barefoot, with your back and heels against the wall, and your legs slightly apart.
- Place a book between your legs, as high as possible, with the book’s spine making contact with your perineum (the part that touches the saddle when you’re sitting on the bike).
- Measure the distance from the floor to the top of the book, making sure the measuring tape is parallel to the wall to avoid skewing the result (it's best to have someone help you with this step).
Get your calculator out!
To calculate the correct frame height (FH) for your MTB based on your inseam (IS), you can use the following formula:
IS X 0.56 = FH
Match the result obtained to your MTB. To do so, measure the frame height by measuring the distance between the bottom bracket and the top of the frame following the vertical tube.
Your body shape and riding style determine the right size. Measure carefully to ensure comfort and efficiency. You are now ready for a successful ride!
