The efficiency of a bike is dependent on how the components of that bike are structured and utilized. If they are used without the application of proper care, and the right mode of operation, you would eventually discover that the bike has been performing averagely; less than the actual efficiency rate.
For instance, Bikes’ gear which performs smoothly, pinpoint the difference which is showcased in the enjoyment derived from riding a bike, alongside with the effortlessness employed. Gears which are not properly indexed could amount to a high level of frustration which most riders are never comfortable with. Just as brakes perform, gears need the right tuning and the smooth management of the cables to perform optimally.
Gears which are produced these days are indexed, hence, as you hit off the gear lever onto a gear which is positioned on the handlebars, the derailleur fixes the chain on the next cog. This is usually done smoothly.
There are three essential parts which would ensure the proper tuning of your bike. They are Pulley cage, barrel adjuster and the limit screws. The limit screws are two in number, the L and H screws. The L limit screw is utilized for the tuning of the low gears, while the H limit screw is employed in tuning the high gears.
The lone tool which is needed for the tuning of the derailleur is the screwdriver; the standard Philips model.
STEPS IN TUNING A BIKE DERAILLEUR
First and foremost, ensure that the back tire of your bike is above the ground. If you have a bike stand, it could suffice. You can also turn the bike upside down to ensure that the bike rests on the handlebars and seat.
The next step is to check your bike; check the gear cable, and ensure that it is not rusted. If it is, it should be replaced.
Next is to check if the chain has stiff links. You can detect this by making the crank face backward and move it through the pulleys. If it jumps, then there are definitely stiff links which would mean that the chain needs replacement. The alignment of the cage needs to be properly in place, as it must be in line with the gears.
Also, tuning the highest gear is essential. Check the H limit screw to ensure it is properly aligned. The barrel adjuster would also come in handy, as it would be used to regulate the cable tension.
In addition to this, check the shifting which is between the gears, in order to reduce noise and the clanking sound, with the aid of the barrel adjuster. The smooth movement of the chain is a good sign. If otherwise, the cable tension should be adjusted till the smooth movement is gotten.
After this step, the low gear should be tuned, this can be done by making use of the barrel adjuster and the L limit screw in order for alignment to occur, and also placing it directly below, just like the case of the high gear.
Once all these are in place, your bike has been properly tuned, and ready for use.
