Buy seatposts online – for MTB, road bike, gravel & e-bike

Whether you're looking for a lightweight carbon seatpost for your road bike, want to upgrade to a sturdy dropper seatpost for your mountain bike, or prefer a suspension seatpost for more comfort on long tours: The range covers all common diameters, designs, and insertion lengths. This means ambitious riders, commuters, or touring cyclists can quickly find the right seatpost for their individual needs – conveniently from home.

Types of seatposts

Rigid seatposts made of aluminum or carbon are the classic choice for road bikes, gravel bikes, and lightweight mountain bikes – they score with low weight and direct power transfer. Suspension seatposts with elastomer or steel spring damping noticeably increase riding comfort on rough roads and gravel paths. Dropper seatposts can be lowered and raised hydraulically or mechanically while riding via a handlebar remote – a decisive advantage on technical terrain, descents, and trails with changing surfaces.

Installation, diameter & insertion depth

The correct diameter is crucial for secure clamping in the frame. Common diameters are 27.2 mm, 30.9 mm, and 31.6 mm – the exact value can be determined with a caliper or is stamped on the existing seatpost. Also note the minimum insertion depth specified by the manufacturer, and use appropriate assembly paste or grease during installation to prevent creaking, corrosion, and seizing.

Who is this category for?

The category is ideal for mountain bikers, road cyclists, gravel enthusiasts, trekking riders, and commuters in Switzerland who want to replace, upgrade, or swap their seatpost for a more comfortable or lighter model. E-bike riders who value ergonomic seating comfort, as well as home mechanics and custom builders, will also find a wide selection of suitable seatposts that are often only available to a limited extent in local shops.

Quality, safety & material selection

When buying a seatpost, it's worth paying attention to high-quality materials, precise workmanship, and compliance with the specifications provided by the frame manufacturer – this ensures the seatpost sits securely, clamps reliably, and provides lasting stable support. Carbon seatposts save weight and dampen vibrations, but require careful installation with the correct torque, while aluminum models impress with robustness and an attractive price-performance ratio.

Frequently asked questions

What types of seatposts are there?▾

There are rigid seatposts made of aluminum or carbon, suspension seatposts with integrated damping for more comfort, and height-adjustable dropper seatposts that can be lowered and raised while riding via a handlebar lever – ideal for technical terrain and trail riding.

How do I find the correct diameter for my seatpost?▾

The diameter is usually stamped on the existing seatpost or can be measured in the frame's seat tube. Common sizes are 27.2 mm, 30.9 mm, and 31.6 mm. A caliper helps determine the exact value so that the new seatpost fits precisely and clamps securely.

How do I install a seatpost correctly?▾

Clean the seat tube, apply assembly paste to carbon contact surfaces, or appropriate grease for aluminum-on-aluminum. Insert the seatpost and tighten the seat clamp to the torque specified by the manufacturer. Make sure not to go below the minimum insertion depth.

What is the correct seatpost height?▾

The correct height depends on leg length and riding position. As a rule of thumb: With the leg fully extended on the pedal, the heel should reach the pedal point without the pelvis tilting. Fine adjustments are made in millimeter increments until a comfortable and efficient pedaling position is found.

What are the advantages of a suspension seatpost?▾

A suspension seatpost absorbs shocks and vibrations from the ground before they are transmitted to the spine. This noticeably relieves the back and seating area and increases riding comfort on long tours, on rough gravel, and on uneven roads.

How do I care for and maintain a seatpost?▾

Regularly remove the seatpost, clean the seat tube and post with a lint-free cloth, and apply fresh assembly paste or grease when refitting. For dropper seatposts, also periodically check the mechanism for smooth operation and keep the seals clean.

Which material is better – aluminum or carbon?▾

Aluminum is robust, attractively priced, and resistant to scratches and impacts. Carbon is lighter, dampens vibrations better, and is preferred for weight-oriented builds, but requires more careful handling and exact torque values during installation.

Can I shorten a seatpost?▾

Yes, many rigid seatposts can be shortened, as long as the minimum insertion depth is still maintained after cutting. The cut should be clean and square. With dropper seatposts, shortening is usually not possible due to the internal mechanism, or only advisable with specialist knowledge.
