Measure wear and replace your chain
The chain is one of the key parts of a bike. A worn chain can quickly undermine all transmission. Regular inspection and maintenance will avoid this problem as unpleasant as it is expensive... Here is how to measure and replace your Road and MTB chain.
1/ Measure
Measure the chain wear. If the wear indicator returns to the "0.75" position, only the chain must be replaced. If the tool returns to the "1.0" position, the chain and the cogset must be changed.
2/ Quick fastener opening
Opening of the chain if there is a quick fastener. Disassemble the quick fastener by moving the axiss closer together with a pair of pliers.
3/ Tip
Tip: you can also use a universal spanner by taking the link diagonally (place the edges of the wrench on the part where the axis is conencted to the link).
4/ Opening rivet
Position the chain derivative correctly, the "teeth" of the chain derivative must be in the middle of the chain. Screw in, making sure that the piton of the chain derivative is properly aligned with the chain axis. Misuse of the chain derivative will cause the teeth to break.
6/ Measure
One of the techniques to select the right chain length is to mount the chain on the large sprocket of the cogset without going through the derailleurs then add 2 or 3 links.
6/ Mounting with rivet
Add 2 external and 1 internal links to mount the rivet.
7/ Quick-release mounting
Add 1 inner link and 1 outer link.
8/ Mounting direction
Some channels are designed with a sense of use: bevelled links on one side and flat ones on the other. Be sure to respect it for optimum operation: bevelled links towards you, flat links towards the bicycle.
9/ Inserting the chain axis
The closure rivet consists of a guide linked together with the chain axis. After positioning the rivet with the guide, place the axis using the chain derivative.
10/ Break the guide
Brake the guide using the universal spanner.
11/ Position of the breaking point
We intentionally inserted the rivet from the inside of the bicycle towards the outside; this way the mount generated by the breakage of the rivet is outside and does not rub on the top sprocket of the cogset.
12/ Mounting with quick fastener
Position the two parts of the quick fastener opposite to each other.
