XLC Suspension Dropper Post SP-S14 – Two Functions, One Post

Imagine dropping your saddle at the push of a button as the trail pitches downhill, then popping it back up to full height the moment you’re climbing again — all without touching the ground. The XLC SP-S14 Suspension Dropper Post combines the functionality of a telescopic seatpost and a suspension seatpost in one sleek, internally routed package. Paired with the included XLC Blaster Remote Lever, it puts complete saddle control right at your fingertips, so you can focus entirely on the ride.

The SP-S14 is built for riders weighing 50–125 kg and features a flat-profile patent head for a low stack height. The suspension can be tuned by air pressure up to 70 mm of damping travel, adapting to your weight and riding style. Available in multiple diameters, lengths, and travel heights to suit a wide range of frames.

Frequently Asked Questions

What is a dropper post and why do I need one?

A dropper post lets you lower and raise your saddle height on the fly using a remote lever on your handlebar. This is especially useful on mountain bike trails where you want a low saddle for descents and a high saddle for efficient pedalling on climbs — without stopping to adjust manually.

Does the SP-S14 come with a remote lever?

Yes — the XLC SP-S14 includes the XLC Blaster Remote Lever as standard. It mounts to your handlebar and allows you to drop or raise the post with a single click.

How is the cable routed?

The SP-S14 uses internal cable routing, meaning the cable runs through the inside of your frame for a clean, uncluttered look and reduced risk of snagging on trail obstacles.

What diameter seatpost do I need?

The most common sizes are 27.2 mm, 30.9 mm, and 31.6 mm. Check your frame’s seat tube inner diameter before ordering. If you’re unsure, contact us and we’ll help you find the right fit.

What rider weight is the SP-S14 suitable for?

The XLC SP-S14 is designed for riders weighing between 50 and 125 kg. The air-pressure suspension can be tuned within this range to match your weight and riding style.

How much travel does this version have?

This listing (SKU 2502080040, Ø27.2 mm / 340 mm) offers 80 mm of travel. Other variants with 100 mm and 120 mm travel are also available — see the variant list above.

Is this post compatible with e-bikes?

Yes — the SP-S14 is test-certified to Category 3 MTB XC/MA (EPAC 120), making it suitable for use on e-bikes in that category.
