Seatposts & Clamps

Seatposts made of aluminum or carbon?

The simplest type of seatpost for both mountain bikes and road bikes is a post made of aluminum both. The material has the advantage that it is very light compared to steel and does not rust. In addition, aluminum seatposts are available in many different colors; so you can set beautiful color accents on your bike.

Carbon offers another weight advantage over aluminum and also looks better. With carbon seatposts, however, you should always pay attention to the specified tightening torques and tighten the bolts only with a torque wrench. If you tighten the seat clamp too tight, the carbon can quickly damage.

Advantage of spring-loaded seatposts?

Flex or spring seatposts bring a great gain in comfort, especially for hardtails or road bikes. To achieve flexibility while maintaining stability, UD Carbon is the solution for carbon suspension seatposts. UD is the abbreviation for unidirectional, which means that all carbon fibers were installed in only one direction, in the case of seatposts in a vertical direction. Since the transverse fibers in the carbon are missing, UD Carbon is very flexible in the horizontal direction and can still withstand high compressive loads. Another approach to ensure flexibility in the horizontal direction is to slit or split the suspension seatpost along its length. The 2 resulting parts now act as a kind of leaf spring, so the seatpost becomes inherently flexible and can also absorb horizontal forces.

Lowerable seatposts

They can be adjusted in height, so before going downhill, you no longer have to dismount to lower the saddle. With lowerable seatposts with remote, you simply press a button on the handlebars and you can lower the post. Especially for mountain bikers who alternately ride uphill and downhill, a worthwhile purchase.

Seat clamp as an indispensable component on the bike

The seat clamp must absolutely prevent twisting or slipping of the seat post in all riding situations. But not only the function distinguishes the smart component. Thanks to countless designs and a wide variety of colors, the bike can be visually upgraded with a few simple steps and a very low cost.

In the saddle clamps must be distinguished in two groups: With and without quick release lever.

A very uncomplicated adjustment of the saddle height ensure saddle clamps with a quick-release lever. Especially in mountain biking, it may be necessary to vary the saddle height without tools depending on the situation. While a high saddle position ensures particularly efficient and joint-friendly pedaling, a lower saddle position favors driving safety in technically demanding passages. When transporting the bike, the quick-release lever can also prove very useful.

A fixed clamping offers the saddle clamp without quick release. A big advantage of this saddle clamp variant is the better protection of the saddle and the seatpost against theft: tools are necessary to release the saddle clamp! In areas of use where the height of the saddle does not have to be varied, the installation of a saddle clamp without quick release can thus pay off. Characteristic of this type of saddle clamp is the usually very smart look. Not only in the field of road cycling and cross-country, the seat clamp without quick release is a very good choice, but also when using a Vario seatpost.

Seat clamp made of aluminum or carbon?

Most seat clamps are made of Alumium. Who places the highest value on an extremely low weight, can fall back on carbon saddle clamps - in the best case with titanium screw.

What should be considered when buying a saddle clamp?

For proper clamping of the seat post, it is essential to use a perfectly fitting seat clamp. For the purchase, therefore, the size or the inner diameter of the seat clamp must be known or determined if necessary. The size of the seat clamp is based on the outer diameter of the seat tube, not the seat post! An exact measurement of the seat tube allows a caliper gauge. For this purpose, the measuring legs of the caliper are guided to the stop on the seat tube. The exact diameter can now be read off the scale.
