Key Installation Tips: If you encounter difficulty while turning the fixing bolt for the first time, begin by inserting the post into the bike frame hole and securing the seatpost clamp. This will enable you to easily turn the bolt using a hexagon screwdriver. Once you successfully move the bolt for the first time, adjustments will become simpler.

Micro-Adjustment: This seatpost features a micro-adjustable clamp that allows for fine-tuning the saddle's tilt angle, ensuring it remains level for a comfortable ride.

Measuring and Confirming Seatpost Diameter: To ensure you purchase the correct diameter for your bike, it's crucial to accurately measure the needed size. Here are three ways to confirm the correct fit:

1. Check Your Current Seatpost: Look for a diameter mark on your old seatpost. For example, if you see "Φ25.4," you can purchase a new 25.4mm seatpost.

2. Using a Vernier Caliper: If you have one, measure the diameter of your old seatpost or the inner diameter of the seatpost hole. If the measurement comes to approximately 27.1mm, then selecting a 27.2mm seatpost would be appropriate.

3. DIY Measurement: In the absence of a caliper, use a small stick to measure the inner diameter of the seatpost hole (refer to the accompanying picture).

Important Reminder: The actual measurement of the seatpost diameter will be slightly less than the marked size. For example, a 25.4mm post will generally measure around 25.0 to 25.2mm.

With these guidelines, you can confidently choose the right replacement seatpost for most bicycles, including mountain bikes and road bikes, ensuring a comfortable and adaptable riding experience.
