What is the removal of a bicycle wheel?

takeaway called part oblong shape, which is intended to connect the steering column and the beam. The official name of the component - the steering bracket.

Tap Install to bicycles to create the right user landing on two-wheeled transport. The correctness of its adjustment largely depends on the comfort of the cyclist during the movement, pedaling efficiency, and safety.

It is worth noting that they brought the set is not for all bike models. Representation of the items are not available in the majority of bikes are intended for the youngest users. Quite often, there is no removal of the bicycle wheel in the simplest road and recreational models. The design of these types of two-wheeled transport steering slat connected directly to the steering column.

Type

There are unregulated and regulated removal of a bicycle wheel. Details of the first type are connected with the steering pin with bolts. Sometimes the fixing elements is done by welding. Unregulated models are distinguished by their static structure, the position of which can not be changed.

In terms of controlled offsets, such models make it possible to adjust the angle and height of the steering bar. Some samples are shown sliding and foldable design that lets you zoom in or remove the wheel relative to the body housing. Certain models include the installation of an extension cord Stem bicycle. Experienced athletes are advised not to mount the bike, which is planned to operate for aggressive driving, adjustable fans. Sharp, significant loading on the item may result in a change in its position directly in the course of driving. This represents a potential danger for both the cyclist and others.

The

What is the impact the size of the removal of a bicycle wheel on the behavior of two-wheeled transport during the ride? The length of the structural element is reflected on the user's convenience and landing, correspondingly, the nature bike handling. The more nominated takeaway in the front direction, the horizontal trim athlete. Convenience such a feature creates, if necessary, the organization of long journeys.

Setting short-removal improves maneuverability of the bike. In this case, it is much more convenient to turn the steering wheel. After all, the crossbar is located in close proximity to the cyclist's body. Thick and short take-away, as a rule, are mounted on two-wheeled transport, which is designed for extreme sports, in particular, performance in disciplines such as BMX and downhill.

The length of some bicycle handlebar stem reaches a maximum rate of 14 cm. The average of the parameter of most of such parts is from 3 5 to 10 cm. The choice of embodiment depends on the intended use of the bike, and the anatomical features of the wearer.

The definition of a suitable removal of length

How to choose a bicycle wheel removal that its length is optimal? To do this, follow these steps:

• Set the saddle of the bike in a comfortable position.
• Push the elbow to the nose of the saddle.
• Straighten thumbs.

The ideal length of removal is considered when fingers touch in the above position, the steering bar. A small amount of the allowance of a few centimeters. Only in this case, the cyclist turns out to be the most comfortable in the saddle during movement.

The materials of manufacture

The cheapest products, for example, to make bicycle wheel "Stealth", other domestic models are made of iron and steel. The main drawback of these materials is their considerable weight. The presence of such a component aggravates the design of the bike, and forces the user to spend extra effort.

High-quality products made of aluminum alloys that are processed by cold forging. However, professional athletes often prefer to install on your bike offsets, made of carbon fiber. Such a solution in combination with other components of the plan promotes the greatest possible reduction in the weight of the bike.

Production Technologies

There are several technologies that are manufactured according to the stem:

1. Welding - data by openly made cheaper models. Most of their weak spot are the seams. The welded joints under severe loads on the workpiece often cracks appear.
2. Forging - Tap, which are produced with the use of such technology, enjoy the highest demand. They are characterized by low weight and high safety factor. In addition, there are no welds.
3. Milling - The technology is based on CNC machines cast parts. Clearances are durable and hardy. These components appear ideal in situations where the bicycle wheel will be provided the maximum load.

Features of dismantling and replacing the stem

A suitable replacement of the component appears in situations when the item contains obvious damage, failure could have an impact on the safety of cyclists during the ride. Clearances that contain no moving compounds dismantled directly with the steering fork rod. To separate the part of the steering crossbar enough to unscrew the bolt fasteners. Install a new take-away for the old snap. It is only necessary to select a suitable embodiment, which correspond to compounds of mounting the other parts of the bicycle.

Finally,

As can be seen, take-away stands a pretty functional piece bicycle design. The city and recreational bikes should be used unregulated option. After all, to spend money on the purchase of more expensive models with the ability to change parameters in these cases does not make much sense. If the user is grafted on a mountain bike or a sprint, with a view to adjusting the landing should consider the option of setting the regulated products.

Be that as it may, the removal must be selected correctly on the basis of the parameters of the cyclist's body. Otherwise, the wrong angle and the length of the negative effect on the efficiency and flow of the rider during pedaling effort.
