Wspornik siodła zwany sztycą, poza łączeniem siodełka z ramą umożliwia regulację pozycji góra-dół, przód-tył oraz kąta nachylenia. Każda firma stosuje własne rozwiązania regulacji i mocowania siodełka do sztycy. ale generalnie można rozróżnić dwa typy: z zaciskiem umiejscowionym w osi rury podsiodłowej, (bezpośrednio nad tą rurą), i z zaciskiem cofniętym w stosunku do pionowej osi rury podsiodłowej. Wybór ma znaczenie raczej dla osób uprawiających wyczynowa jazdę - decyduje to bowiem o położeniu siodła w osi poziomej roweru.Mocowanie i regulacja odbywa się za pomocą jednej, lub dwóch śrub imbusowych. Rozwiązania z dwoma śrubami pozwalają na dokładniejszą regulacje pochylenia siodełka.
Klasyczna sztyca - mocowanie z jedną śrubą
Starsze typy
W starszych i tańszych rowerach można spotkać inną konstrukcję mocowania siodła składającą się z rury (zazwyczaj stalowej) oraz z jarzma (patrz zdjęcie obok) ściskającego pręty siodełka poziomą śrubą z sześciokątną nakrętką. Regulacja takiego mocowania jest trudniejsza niż w obecnie stosowanych wspornikach jednoczęściowych z zintegrowanym z rurą jarzmem.
Samo jarzmo ma tez tendencje do wyrabiana się z czasem co powoduje samoistne luzowanie się tej części w czasie jazdy.
Rozmiary sztyc rowerowych
Kupując nową sztyce rowerową musimy wiedzieć jaki rozmiar będzie pasował do naszej ramy. Niestety nie jest tutaj taka prosta sytuacja jak w przypadku kierownic gdzie mamy 3 rozmiary. Jest dostępnych około 17 rozmiarów sztyc od 25 do 32,4 mm. Niektóre z nich różnią się o zaledwie 0,1 mm np: 30,8 mm i 30,9 mm.
Najpopularniejszymi rozmiarami sztyc podsiodłowych są:
27,2 mm
31,6 mm
Jaki zacisk (obejma) do sztycy?
Zacisk blokuje wspornik siodełka w rurze podsiodłowej. Do każdej średnicy sztycy musimy dopasować odpowiednią średnicę zacisku.
Nie ma żadnej ścisłej reguły - że jednemu wymiarowi średnicy sztycy odpowiada jeden rozmiar zacisku (obejmy). Najlepiej samemu sprawdzić dopasowanie. Poniżej tabela najczęściej występujących rozmiarów zacisków i przyporządkowane im rozmiary sztyc.
Średnica sztycy
27,2 mm
30,9 mm 31,6 mm
Zacisk
28,6 mm
30,0 mm
31,8 mm
34,9 mm 35 mm
36,4 mm
38,5 mm
Zaciski (czasami tez określane obejmami) występują w dwóch wersjach: ze śrubą i z dźwignią. W rowerach miejskich - które często zostawiamy przypięte lepiej użyć obejmy ze śrubą. Z kolei w rowerach MTB lepsze są zaciski z dźwignią - ułatwią zmianę wysokości siodełka podczas zjazdów i podjazdów.
Zacisk ze śrubą
Zacisk z dźwignią
Wady
Wymaga użycia klucza do regulacji wysokości siodełka
Nie wymaga użycia klucza do regulacji wysokości siodełka
Zalety
Utrudniona kradzież siodełka
Ułatwiona kradzież siodełka
W krytycznych sytuacjach można zastosować tuleje pośredniczące.
Amortyzacja
Coraz większy popyt na amortyzowane sztyce podsiodłowe sprawiają, że w ofertach firm zajmujących się produkcja sztyc pojawia się coraz częściej ten rodzaj wspornika. Pełnej amortyzacji taki wynalazek z pewnością nie zastąpi, ale na pewno przyczyni się do zwiększenie komfortu oraz przyjemności z jazdy na rowerze.
Regulowana sztyca podsiodłowa
W ostatnich kilku latach furorę robią regulowane sztyce podsiodłowe pozwalające w czasie jazdy zmienić wysokość siodła. Głównie stosuje się je w rowerach górskich - gdzie do podjazdu powinno być ono jak najwyżej, a w czasie zjazdu obniżone.
Do wyboru mamy dwa rodzaje regulowanych sztyc podsiodłowych - z dźwignią do regulacji umieszczona pod siodełkiem i na kierownicy. Z oczywistych względów drugie rozwiązanie jest lepsze i droższe. Dzięki manetce umieszczonej na kierownicy bez odrywania ra możemy zmienić swoja pozycję na rowerze.
Sztyce regulowane są niestety drogie - ceny zaczynają się od 800 zł

12 simple exercises to develop "phenomenal memory":
1. Improve the memorization process
When memorizing something, you need to think about the action, draw parallels with your life. Let's just say, the more associations you make, the more you will be able to remember what you want.
2. Try to remember yourself
There are times when you forgot your partner's phone number, or the name and patronymic of a person with whom you have an important meeting, etc. Do not rush to open your notebook just to read the necessary information. Try to remember it yourself. This information is already "on the shelf in your head", you just have to find it.
3. Create similar looks
If you need to remember something important, try to create an image in your mind that is associated with what you need to remember. It will be easier for the brain to do this.
4. Speak the information received
When you want to remember important information, try retelling it, or explaining it to another person. The memorization process becomes better when you speak the information received.
5. Do arithmetic
how to write a header for an essay <a href="https://essaywriterserv.net/">online essay writing</a> creative ways to write an essay
When you have nothing to keep yourself busy in boring and long lines, try to start solving very simple arithmetic problems in your head. For example, multiply the number of legs of those red chairs by the number of flowerpots on the windowsill. Or count the sum of numbers on the numbers of passing cars ... This practice is actually an excellent memory training. 6. Remember what happened to you during the day
Before going to bed, after the day, scroll through all its details in your head. What did you do throughout the day, what would you do to improve some points. Think back to your day. From now until awakening. Believe me, this is not an easy task! Ask the question: "Which decision I made today was the most effective?"
7. Read more books!
What could be better than spending your free time reading an interesting and useful book? When reading a book, the brain strains to memorize the details. In addition, you turn on your imagination and begin to visualize everything that you read about. This is great for training the brain.
8. Study verses and text passages
At school we were asked to learn poems for a reason. Memorizing rhymed verses and non-rhymed passages of text helps develop memory. So learn the verses. Try to choose those pieces that you really like 9. Don't try to cram!
Remember how at school / university we could memorize the information we needed to get a good grade? Forget about it. This technique does not help develop memory. Dull cramming is ineffective. It tires the brain, and it quickly stops responding to the information it receives. Better ponder on what you read. You need to not only learn, but also understand what you are reading.

10. Repeat
But it's still worth repeating the material covered. Not to cram, but to repeat - to refresh your memory. As they say: "Repetition is the mother of learning." Repeat the information received. Every day, for example, 5 days. Repeat what you learned. This information will be deposited in long-term memory, and you can easily get it from there.
11. Don't be lazy
You will never be able to achieve something and remember something if you are lazy. Laziness is the rust of the mind. Don't let it take over your memory. Resist the temptation to lie idle on the couch. Take a book or turn on some relaxing music. This will force your brain to work and thus improve your memory, while you physically rest. And if you need to remember something, then quickly connect all the resources.

What is MBA education?
essay+writer+service <a href="https://buyessaysfjd.com/">url</a> cuwstom essay writing service
(Master of Business Administration, master of business administration) is not so much a training program as a Manager's degree (in management). Here it is important to have it, which indicates that you have the skills necessary for a middle-and senior-level Manager. To date, there is no single standard that would allow you to divide the degree of proficiency in these skills, so only the fact of having a corresponding diploma is taken into account.
The first version of such a training system began to be used in the United States in the 19th century. for many companies of that time, employees who knew the latest management methods were in demand. With
In our country, the MBA program started at the branch of the Plekhanov economic Institute. Since then, the standard has taken root and MBA education is now considered one of the mandatory for prestigious vacancies in the economic sphere.
What is the" strength " of MBA education?
As with any other type of training for MBA education, there may be pros and cons. So among the main positive qualities can be noted.
8 hr essay writing service <a href="https://buyessaysfjd.com/">buy essays papers</a> essay topics on customer service
The opportunity to gain in-depth knowledge in the field of business, from which you can get practical benefits in your daily work.
Increased chances of becoming the head of a large firm. The owners of this education are guaranteed to move up the career ladder.
Getting first-hand knowledge from world-class businessmen, and perhaps even from Nobel prize winners.
A great opportunity to get a job abroad or in our country, but in an international organization.
In General, MBA education increases the qualification level of a specialist, making it more competitive in the job market. But there are a few disadvantages.
For example, today young professionals who have just graduated from UNIVERSITY are trying to get an MBA right away. The motivation is obvious — they want to immediately get a job in a prestigious company for a high-paying position with a career growth forecast. And there may be no time to get additional education in the future. But here's the problem — the MBA provides practical knowledge in contrast to the usual "HSE", which would be better compared with your own business experience. This is the only way to highlight in the entire course the knowledge that will really help in a particular situation. And without experience, everything becomes nothing more than an interesting educational program.
The second disadvantage is again hidden in the lack of practical experience for most of the owners of MBA crusts. It is difficult for them to apply the existing knowledge in practice, they do it with caution, sometimes being late with responsible decisions. To work successfully in a rapidly changing market, you need to work for many years to develop the skills to solve complex problems on the fly.

Home education pitfalls.
We lived in a provincial town. I was very surprised that before us in a neighboring school from the 8th grade, parents took their son to family training. My father taught me. The headmaster of that school proudly announced that the boy returned a year later: "It was hard." The boy pulled it out, passed it well, but didn't want to do it again.

The first pitfall
What happened to the first boy in family training in our city is the first pitfall. We came across it in the 5th grade. This is the desire of teachers to interrogate (do not ask!) a non-standard student on all issues. No student answers on all topics in all subjects. Only those who are in family training.
I was acutely aware of the teachers ' desire to prove that the system they serve is better. So that others don't get hurt. We found a way out: another school.
Choose the form of training: external. They will impose fewer requirements.
The second pitfall
My mother-in-law worked as a teacher all her life. The students loved her. She took our idea of home education badly. We were lucky to live in different cities.
Once she arrived for 2 days and, as it turned out, did not have time to go to school! I wanted to talk to the class teacher, so that the girl was asked more strictly, so that she didn't want to study at home.
It was a failed betrayal. Sticks in the wheels can be inserted by anyone who does not feel sorry for the child. Such people were always on the way. But my own grandmother...
