Bicycle gears are an inseparable piece of equipment that makes it easier and easier to ride a bike on any type of road. It is worth devoting a moment to their right choice and learning how to properly change gears.
How to change gears?
In the context of changing the bicycle gear, one must remember about a few basic rules:
- for higher climbs it is recommended "soft" (lower) gears
- for stricter descents should choose "harder" (higher) gears
- you can not change gears during intensive pedaling
- Gradually reduce gear ratios
In order to avoid overloading the derailleur to the bicycle and tearing the sprockets, one must think ahead of time, anticipating given situations. Changing gears during a sharp downhill or driveway is very unfavorable to the gear mechanism. When you see the elevation, you must change gear before. Thinking forward, cycling will be more fluid, and by the way will not hurt the drive!
What's more, having a bicycle with derailleurs above all you cannot cross the chain, because it will cause a faster clash of teeth on the discs of the cartridge and the crank set. In addition, such a ride will also slow down the pace of the cyclist.
In road bikes, the gear shift paddle makes it easier to select the ratio by using the half-gears that are used to trim the front derailleur. Thanks to this, you do not have to change the whole run.
How to adjust the derailleurs?
Adjusting the derailleur in the bike requires the use of an Allen key and a cross-head screwdriver. Before adjusting the front or rear derailleur, first check the condition of the derailleur cable and lubricate it a little. In addition, you can look at the derailleur hook and armor. If any of the elements is damaged, it must be replaced.
Adjusting the rear derailleur
If you want to adjust the rear derailleur you should:
- dump the chain on the smallest sprocket on the back with the shifter and the largest sprocket on the front,
- loosen the screw holding the gear cable,
- the derailleur discs must be in the same line as the smallest sprocket - if this is not the case, turn the H-bolt that fits in the bracket body,
- then move the derailleur towards the wheel and with the other hand put the chain on the largest cassette sprocket - here you use the L screw to adjust the position,
- finally, you can turn the crank of the bike - if the chain returns to the smallest sprocket, it means that everything works smoothly and just pull the cable back and tighten the clamping screw.
Adjusting the front derailleur
Adjusting the front derailleur in the bike:
- The most convenient will be to put the bike on a bicycle stand, then place the chain on the center rack of the cassette. To this loosen the screw from the cable to the front derailleur and set the smallest disc on the front,
- using the l screw should establish the derailleur guide to the position perfectly in the middle of the front disc, after which you can pull the derailleur cable and tighten the screw,
- Then it is recommended to set the derailleur on the largest disc and crank the crank until the chain is there. Then screw will be used for adjustment
- verifying the gears one should observe the chain when changing the location from the middle dial to the smallest one,
- if necessary, depending on the position on the disc, tighten the h or l screw,
- if there are no problems, you can pull the cable back into the derailleur and tighten the bolts.
In addition to adjusting the derailleur, it is also recommended to clean the chain from the black sediment accumulated on it.
What gears for the bicycle?
Cyclists should choose one of two types of bicycle gears:
- External derailleurs - they are lighter, have a simpler construction and are easier to service. They perform very well on difficult off-road tracks, and provide a larger range of gears. Most often, therefore, they are equipment for mountain and road bikes.
- Internal derailleurs - they are heavier, more complicated and harder to repair. Instead, they make it possible to change gears when stationary, they are mounted in the hub, so they are great for city bikes. In addition, they enable the installation of a chain cover that protects the chain against weather conditions and protects the clothing.
When selecting the gearbox, also remember about the throttle. In city and tourist bicycles rotary or rotating levers are ideal. Road clerics are on the roadside.
In summary, the gears in the bike, despite their inconspicuous size, are an essential element of the bicycle propulsion system, which is responsible for changing the gears in the bike. They can significantly facilitate the ride and increase the cyclist's comfort. The basis for this is their regular adjustment and knowledge of shifting rules.
