How to Check if This Suspension Seat Post Tube Will Fit Your Bike

To make sure the Adsports ASSP272-300 Suspension Seat Post Tube is right for your bike, you’ll need to check the fit with both your bike frame and your existing saddle clamp.

1. Confirm Seat Tube Internal Diameter

• Remove your current seat post from the bike frame.
• Look for a size marking engraved near the base of the post — if it says “27.2 mm,” this post will fit directly.
• If there’s no marking, measure the outside diameter of your existing post with a vernier caliper. It must measure exactly 27.2 mm.

2. Check Your Saddle Clamp Type

• This seat post tube does not include a rail clamp — it is designed to be used with a separate, compatible clamp.
• Ensure your current saddle clamp fits a 22 mm clamp area diameter and is designed for standard saddle rails (7 mm round rails are most common).
• If you don’t have a clamp or yours isn’t compatible, you’ll need to purchase a separate one before installation.

3. Insertion Depth Requirements

• Your bike frame must allow for at least 100 mm of the post to be inserted for safe riding.
• Do not insert more than the 260 mm maximum to preserve suspension travel and prevent frame damage.

4. Rider Weight Range

• Optimised for cyclists weighing between 50–100 kg.
• Provides best performance across NZ’s varied urban, gravel, and light trail conditions.

Tip: If your frame uses a different seat post size, you may be able to use a shim adaptor to fit this 27.2 mm post tube. Contact us if you’re unsure which shim to use.
