Szybkozamykacz koła typu quick-release - jak obsługiwać?

Szybkozamykacze czyli zamknięcia piast typu Quick-Release służą do szybkiego i beznarzędziowego odkręcania kół z roweru. Są powszechnie stosowane w rowerach górskich oraz turystycznych już od wielu lat. Czasami znajdziemy je też w rowerach miejskich. Mimo swojej prostoty potrafią sprawić trudność użytkownikom rowerów.

Szybkozamykacz koła typu quick-release

Wątpliwości mogą dotyczyć trzech aspektów:

  • Jak zamontować szybkozamykacz
  • jak mocno należy zaciskać dźwignię
  • w jakiej pozycji powinna być dźwignia szybkozamykacza

Jak zamontować szybkozamykacz

Na początek warto powiedzieć na jakiej zasadzie działa zamknięcie Quick-Release. Dźwignia zastępuje zwykłą nakrętkę, którą normalnie musielibyśmy zakręcać za pomocą klucza. To tak jakby klucz był już na stałe przymocowany do nakrętki. Szybkozamykacz składa się z główki, szpilki, sprężynek  oraz dźwigni. Wbrew pozorom cały ciężar roweru nie spoczywa na tej cienkiej szpicle. Właściwa oś na której opierają się koła znajduje się w piaście i jest pusta w środku. Haki widelca spoczywają na końcach tej osi. Szybkozamykacz dociska nakrętki z obu stron nie pozwalając jedynie na wysunięciu się koła z widełek.

Szybkozamykacz koła typu quick-release

Zauważmy, że dźwignia szybkozamykacza ma napisy po każdej se stron: "Open" - wtedy gdy jest otwarta (poluzowana) i "Close" gdy jest zamknięta. Bardzo ważne jest aby po założeniu koła i zaciśnięciu dźwigni widoczny był napis "Close"

Jak mocno należy zaciskać szybkozamykacz koła

Przechodzimy do kwestii - z jaką siłą trzeba zamykać dźwignię szybkozamykacza? Sprawa jest dosyć prosta: nie trzeba wcale mocno tego robić. Dźwignia powinna zamknąć się z mocnym oporem, ale na tyle małym, aby bez większego problemu docisnąć dźwignię do końca. Wystarczy w tym celu użyć dwóch palców - wskazującego i środkowego i przyłożyć przy tym sporą siłę.

Wbrew pozorom zbyt mocne zaciśnięcie dźwigni nie jest dobre, a nawet jest szkodliwe. Jeśli zrobimy to zbyt mocno - koło może się obracać z większym oporem, a łożyska ulegną szybszemu zużyciu.

W jakiej pozycji powinna być dźwignia szybkozamykacza piasty

Zanim dźwignię zamkniemy, najpierw trzeba ją ustawić w prawidłowej pozycji. Powinna być ona ułożona wzdłuż rurek widelca lub ramy. W przypadku przedniej piasty powinna być skierowana w górę. W przypadku piasty tylnej poziomo. Dlaczego jest to istotne? Jeśli dźwignia będzie skierowana pionowo w dół może się zdarzyć, że się otworzy, gdy najedziemy na przeszkodę typu kamień, wysoki krawężnik, czy pień drzewa. Oczywiście nie jest to duże prawdopodobieństwo, niemniej jednak skutki takiego zdarzenia (otwarcie dźwigni i samoistne wysunięcie się koła z widełek) mogłyby być bardzo bolesne.

Drugim argumentem za takim ułożeniem dźwigni są... wrażenia estetyczne. Dźwignia ułożona wzdłuż widelca i ramy wgląda po prostu ładnie i "profesjonalnie".

Dźwignia szybkozamykacza piasty z lewej, czy prawej strony roweru?

Nie ma to większego znaczenia, ale przyjęło się, że dźwignie montujemy po stronie przeciwnej niż napęd (czyli po lewej stronie roweru). Czasami konstrukcja ramy wręcz wymusza taką lokalizację - inaczej po prostu się nie da prawidłowo ułożyć dźwigni (dotyczy to tylnej osi).

Sprężynki szybkozamykacza piasty

Nie jeden rowerzysta zastanawiał się jakie zastosowanie mają dwie małe - i łatwo się gubiące - sprężynki na szpilce zacisku quick-release. Nie są one niezbędne do działania urządzenia, ale znacznie ułatwiają zakładanie koła. Ich zadaniem jest rozpychanie końców zacisków, tak aby nie przeszkadzały podczas wkładania osi koła do widełek.

Ta czynność jest już prosta - wystarczy odchylić dźwignię do pozycji "open" a następnie odkręcić główkę szybkozamykacza. Nie trzeba robić tego do samego końca. Wystarczy poluzować, tak jak to jest pokazane na filmie.

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
what are five consequences of world war i? write your answer in an essay of at least 125 words. <a href="https://essaywriterserv.net/">high school vs college essay</a> how to write common application 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.
