Absolutely, the obsession with conventional wheel sizes in mountain biking is worth questioning. Different wheel sizes do have unique advantages and disadvantages, and it's crucial to consider these when choosing the right wheel size for your riding style and terrain.
Smaller wheel sizes, such as 26" or 27.5", offer better maneuverability and quicker acceleration, making them ideal for tight, technical trails. They also require less effort to lift off the ground, which can be beneficial for tricks and jumps.
On the other hand, larger wheel sizes, such as 29", offer increased rollover ability and stability, making them ideal for more open, rough terrain. They can also maintain speed better on flat sections, and are generally better at carrying momentum over obstacles.
However, it's important to note that wheel size is just one factor to consider when choosing a mountain bike. Other factors, such as frame geometry, suspension design, and tire choice, can also have a significant impact on performance and versatility.
Ultimately, the best wheel size for you will depend on your individual needs and preferences. Don't be afraid to experiment with different wheel sizes and setups to find what works best for you!
