Does a wheel size matter on fixie?

Yes, wheel size does matter on a fixie. The size of the wheel affects several factors, including:

1. Rolling Resistance: Larger wheels have lower rolling resistance, which means they roll easier and require less effort to maintain speed. This can be advantageous for long-distance rides or racing.

2. Acceleration: Smaller wheels accelerate faster than larger wheels. This can be useful for track racing or urban commuting, where frequent starts and stops are required.

3. Handling: Larger wheels provide better stability and handling at higher speeds, while smaller wheels are more agile and easier to maneuver in tight spaces.

4. Geometry: Different wheel sizes can affect the geometry of the bike, such as the bottom bracket height, seat tube angle, and head tube angle. This can impact the bike's handling, comfort, and overall performance.

5. Tire Selection: Different wheel sizes accommodate different tire sizes. Larger wheels can fit wider tires, which provide better traction and shock absorption. Smaller wheels may require narrower tires, which are faster but less comfortable on rough roads.

6. Braking Performance: Larger wheels have more rim surface area for the brakes to grip, resulting in better braking performance. Smaller wheels have less rim surface area, which can reduce braking power.

7. Visual Aesthetics: Wheel size can also affect the bike's overall aesthetic appearance, with different sizes creating distinct visual characteristics.

Ultimately, the best wheel size for a fixie depends on the individual rider's needs and preferences, considering factors such as riding style, terrain, distance, and personal preferences.
