A reliable seat post - a guarantee of a comfortable ride
The seat post is a partbicycle, which acts as a connecting link between the frame and the seat of a two-wheeled vehicle. Depending on the design, the element can be fixed with a bolt or eccentric clamp. The upper part of the seat post contains a lock, which serves as a means for fixing the seat guide.
Materials of manufacture
- aluminum alloys - are now actively used to produce a wide variety of pin models, from the lowest level to the top products;
- steel - the simplest option, which can be seen on cheap bicycles;
- Carbon plastic is a strong and light material that is used in the manufacture of seatposts for modern highway and cross-country bicycles;
- titanium - an effective solution for the production of structures that are installed on high-level bikes (due to high cost, it often becomes the choice of professional athletes);
- scandium - an unused, but at the same time, high-strength and lightweight material, from which the seat pins of the highest class are made.
Hard Pin
Integrated pin
It is a monolithic construction connected to the bicycle frame. Most often, the material used is carbon.
Often an integrated seat postcast once, specifically in accordance with the parameters of the body of the owner of a two-wheeled vehicle. Therefore, this design does not allow you to adjust the height of the landing.
Specific in nature, the technology is designed primarily to ease the bicycle. In operation, functionality and convenience are somewhat affected.
Pin with automatic height adjustment
The adjustable seat post is useful, first of all, to the owners of the downhill bikes, who need a quick change of the saddle position with extreme, high-speed off-road driving.
Seatpost with shock absorber
It is based on the application of a mechanism thatprovides softening of blows when the cyclist performs jumping tricks and overcoming difficult sections of the trails. A seat post with a shock absorber enables extreme sportsmen to feel more comfortable when traveling.
According to the design can be lever or telescopic. The main production material are lightweight aluminum alloys.
Types of locks
The lock is an element of the seatpost that servesto connect the upper base of the structure with the saddle, adjust its longitudinal displacement and inclination. It can be presented as a separate part, which is suitable for installation on various options of pins or be integrated with the saddle.
According to the design, the locks are divided into the following types:
- Single-bolt - provide the possibility of fairly rough adjustment of the position of the saddle.
- Double-bolt - allows you to perform precise adjustment of the inclination and displacement of the platform for landing a cyclist
- Locks of the original design - patented, complex products of individual manufacturers. Differ in specific assembly and functionality.
Service
Lubricate the seatpost pin is recommended asat least once in the off season. Initially, the holding eccentric is loosened or the bolted connection is opened. The seatpost for the bike is released from the frame opening. Subsequently, the old grease is removed and a new one is applied. Before performing the procedure, the surfaces are pre-cleaned of accumulated impurities.
At the end of the pin is installed back into the frame of the bike. The seat position is adjusted, the eccentric or bolt fastener is securely fastened.
Finally
There are several bike accessorieswhich is not worth saving. These include steering columns, brake systems, fasteners. There is no exception and seatpost, which plays the role of vital details. The latter should be selected depending on the type and purpose of the bike, riding style, needs, goals and objectives of the bike owner. An unexpected component breakdown can cause serious consequences in the form of injury or the creation of a potentially dangerous situation on the road.
