Fans of this sport face a problem of the bent bicycle wheel regularly and that every time not to pay the decent sum of money for its elimination, have to know how to correct the eight by bicycle independently.
How it is correct to correct the eight on a bicycle wheel?
There is an easy way helping both to correct the eight on a back wheel, and to eliminate similar breakage on front. To use it it will be necessary to find the following tools and devices:
- Spoke a key by means of which fastenings of needles will be weakened and be tightened. It can be got in specialized shop, such tool costs not much, and will serve long therefore you do not stint and spend money for it.
- Piece of chalk or water marker, they will need to put marks at breakage elimination.
- Universal crow bars from plastic which are also on sale in specialized shops.
After the tool is assembled, to correct the eight on a bicycle wheel becomes a matter of time. The first that should be made, it by means of crow bars to remove tires and to define where the eight begins and where it comes to an end, that is it is necessary to find the center of breakage and the main needle in it. Now we define the party of a blockage of the eight, will depend on it from what needle we will begin to work. For an example let's consider how to correct the eight on a wheel with a blockage to the left:
- Having found damage, we define an opposite needle and we tighten it on 1 turn of a spoke key.
- We choose two nearby the damages of a needle standing the place, we weaken them a little, approximately is twice less, than tightened previous.
- We move to the opposite side, we find a needle which was tightened before, two nearby standing it too a little tightened.
- We move to the party with damage, we find on one needle near what was weakened before, and too we weaken them a little.
It is necessary to repeat this sequence of actions (Paragraphs No. 2-4) until all needles of a wheel are not corrected. Consider that whether it is necessary to trace constantly the situation became worse if still big deformation is observed, it is necessary to return to already tightened or weakened needles and to reduce or increase quantity of turns. You do not hurry whether it will be possible to correct the eight by bicycle independently in many respects to depend on whether there will be enough at you patience constantly to keep track of quantity of turns and if necessary to return and redo work.
We define quantity of turns during the work with a key
Experts at elimination of such breakages are guided by the simple rule – what further the needle is located from the defeat center, those should do smaller quantity of turns. It is necessary to begin work always about less than 1 turn, each subsequent needle has to be tightened or weakened approximately twice less, than previous. In order that it was more convenient to you to work, use a piece of chalk, note on a wheel rim how many turns you made a key, so you will definitely not get confused even if you for a while will interrupt process of easing or tightening of needles.
Do not forget that after completion of works the wheel needs to be scrolled several times, this kind of test will allow you to understand whether correctly structural elements around an axis move now. If results of check are unsatisfactory, then everything should be remade anew as it means that you after all somewhere too tightened or weakened fastenings of needles.
