One thing you will think very normal, it takes .... but I think two more words not spoil ever.
Some manufacturers chains such esempiol'italianissima REGINA explains how to deal with a chain:
Cleaning
Normally the operation of chain lubrication is sufficient to ensure at the same time washing.
If, however, excessive accumulation of dirt (sand, earth, asphalt and other debris particles) is necessary to intervene with fuel oil or kerosene and proceed immediately with compressed air drying of the chain.
In the case of off-road, removing mud, dirt or sand with a jet of water and proceed immediately Chain of drying compressed air.
Immediately after washing, the chain is lubricated
again as described in the following chapter.
Lubrication Proper lubrication is the restoration of an operation of great importance for the long term and for the best performance of the chain.
As the function of the lubricant is to reduce friction, a lack of lubricant, or the use of a product does not fit, cause an increase in friction, especially in the work area between pin and bushing.
This absorbs energy, which transformed into heat and leads to rapid wear of the metal components of the transmission. In addition, the increase in temperature makes the fluid lubricant, so it will tend to leak from the joints of the chain, causing a further increase in friction. In this case proceed as soon as the restoration of proper working conditions.
obvious signs of poor lubrication rapid chain elongation, the appearance of reddish areas (index of rust), the presence of transmission noise and squeaks.
Or as written on the website of the KMC (KMC since 1997 began the manufacture of chains for bicycles) a world leader in the field of chains:
When effecting such maintenance of the chain?
Maintenance depends on the type of use, of course use on gravel roads and muddy program requires a more intense use on paved roads and does not require routine monitoring.
Here are some tips for knowing when effecting such maintenance
- reduced flexibility ';
- dirt and external agents (which are deposited on the crank)
- squeaks when you change gear;
- clink of the chain when passing over bumps or use (too dry);
- for every 250 road use km or once a month;
- for off-road per 100 km. 
Cleaning - Clean your chain after each trip, especially when used in wet conditions.
- Always use a dry cloth to clean the chain and its parts.
- If necessary, use an old toothbrush to clean the inside of the mesh.
- Do not forget to clean the teeth of the crank and the freewheel gear.
- To remove mud and sand, use a brush with hot soapy water.
- Never use detergents, acids, these agents can damage the chain and cause breakage.
- Never use a chain cleaner with solvent, and that 'the most' fast
to ruin your chain.
- Avoid the use of solvents that harm the environment as well as removing the lubricant from the bearings.
lubrif ication - lubricate the chain every time you clean the ol 'dry (remember that we do not recommend the use of solvents
)
- before lubrication make sure that the chain is dry;
- use a lubricant which initially both liquid and penetrate into the bearings and
hidden points of the chain, but at the same time it dries quickly so as not to slip away
;
- you can check that the product is suitable for spraying a bit 'on the hand, which notere
initially and 'very liquid (to reach hidden areas), and soon after became
appicicoso (for durability);
- accumulator to avoid excess fat, the fat applied only to the main chain of
(bearings). l 'application of fat helps to reduce wear and noise;
- apply a layer of grease on the chain to prevent rust;
- remove excess grease from the chain;
- for bikes with change, perform the same operations above for the change and the wheel
free;
- after lubrication, use a dry cloth to remove excess lubricant, which prevents
that external agents (dust, sand) kneading it on the chain. Before reconnecting your chain do not forget to clean both ends and make sure that there are no remnants of dirt, also do not forget to grease the pins falsamaglia.
"A chain is not 'just a chain but the heart of your bike"
We hope that reading this booklet will be served to know more' to understand this simple product called chain.
chain and 'probably the most' important of your bicycle, works well when you do not even notice it, but if not then you might suddenly find yourself on foot.
prevent wear chain We can give you the following tips to maximize the life of the chain (except when used for high performance or normal chains): - follow our guidelines for maintenance.
- when you change gear, try to maintain alignment between the crank and the freewheel.
For example, never use a combination of small crank gear teeth with large
free wheel and the opposite.
- when you change gear, try to anticipate situations, for example, before a climb
already prepared 'a proper relationship and efforts to avoid pulling the chain.
- before stopping, put the gear in an ideal position to share. Some people use 2 or 3 chains and change them every week, this method reduces the wear of the crank and the freewheel (which are the most 'expensive).
To control the chain elongation understand easily when it 's time to change the chain because' lose 'its flexibility' and notice problems changed.
A rough way of checking: - put the chain on the more 'big crank, and then lift up the middle. - If you can raise it more 'than 1cm, the chain and change. Often, and unfortunately 'already' too late 'cause you may have already ruined the clutch or crank. KMC has created
a special indicator electronical Elongation of the chain, the 'check chain'.
atrezzo This allows to accurately measure the elongation of the chain, and then change it at the right time (not too early and too late) thus preventing the deterioration of the crank and the freewheel. KMC suger
Generally the following controls: - road use, good weather conditions: for every 500 km - off-road, adverse weather conditions: each 150 km.
Note: the length of the chain varied depending on the product taken from the circumstances in which the use and maintenance that you perform.
- The easiest way to control the
- digital mode to control
- Avoid extreme positions change!
- Proper chain length
Place the chain on the largest 'small crank and freewheel: The chain must be as' close as possible but without touching the return.
What say more is to explain everything word for word what and how do I want to add just a few my comments, for example I abandoned the use of biodegradable products MUC-type OFF, in my opinion just because they do not clean as say I "my" chain, so I relied use kerosene (or white oil), given that polluter, with each wash chain with this product and exchange rate system on the ground of old rags that go to absorb the falling debris during washing, dry cloth as soon as I keep in a ventilated place.
forgot ... I strongly advise against the use of aerosol products for cleaning chains, first because they cost a blunder, it would take an entire second spray to clean a decent chain ... do you ...
I also commend using a classic tool to clean the chain before hand with a brush with hard bristles that will clean the parts (chain, sprockets, gearboxes, front derailleur) and then with my old chain cleaner BARBIERI with over 15 years of loyal service .... Two or three cycles of cycling than thirty times each, and then immediately passed by a compressor, knitted mesh, until completely dry chain and parts coming into contact with the white oil.
And now oil (I use Finish Line of the WET to the green pack, thick oil that does not collect too much dust) mesh knitting, running chain, this end, a few minutes off and then pass the chain on a rag to remove excess oil on the white cloth so that you have to clean the chain , a slim, black / ... will always appear gray unless you change the chain !!!!!! Tranquilli white, for both the clean, you will not see ever ... guaranteed.
... ready for a new ride.
